1.2 General Information
The Texas Instruments LP5562EVM evaluation module (EVM) helps designers evaluate the operation and
performance of this device. The LP5562EVM uses the LP5562 LED driver to create special lighting effects
for RGB LEDs and/or WLEDs. Information about LED driver characteristics and current ratings of LP5562
can be found in the datasheet.
In order to facilitate ease of testing and evaluation of this circuit, the EVM contains a TI MSP430
microprocessor to provide easy communication via USB. EVM also contains an external power supply
connection for the VIN and VEN. Test points for all of the signals can also be found on the evaluation
board.
For evaluation purposes, the EVM has been tested over a 2.7V to 5.5V input range. This voltage range is
within the absolute maximum input range of the LP5562. Users are cautioned to evaluate their specific
operating conditions and choose components with the appropriate voltage ratings before designing this
support circuitry into a final product.

2.3 Power Sequences
2.3.1 Startup
The LP5562 is started when VDD is above POR threshold (1.9V typ.), EN signal is high and chip_en bit is
set high. Allow 1 ms wait before sending data to the LP5562 after the rising edge of the EN signal. After
setting chip_en bit high startup delay is 500 µs (typ).
2.3.2 Shutdown
The LP5562 is shut down if EN signal is set low. When EN signal is set low, chip_en bit is set to 0. If VIN
voltage drops below 1.9V (typ.), the device is reset. Reset can also be applied from RESET register by
writing FFh.
If the device temperature rises too high, the Thermal Shutdown (TSD) disables the device operation, and
the device is in STARTUP mode, until no thermal shutdown event is present.

LP5562 Evaluation Module
3.1 Setup
The LP5562 EVM is connected via USB to the computer. The EVM is controlled with special evaluation
software. An MSP430 microcontroller is used with the EVM to provide easy I2C™ communication, external
32 kHz clock control, and EN -pin control with the LP5562 via USB. The EVM board and LP5562 device
are powered by default via USB.
When the board is connected to a computer, Windows should recognize it automatically and start to install
the driver. A “Found New Hardware” dialog box will prompt you to locate the missing driver. Select “No,
not this time” and continue with “Next”. Select “Install from a list or specific location (Advanced)” to install
the driver. Select the directory where the TI_CDC_Virtual_Port driver is. Windows should now install the
driver, and the PC can communicate with the evaluation module using a virtual COM port. If Windows
cannot find the driver, you need to manually install the TI_CDC_Virtual_Port driver from the Device
Manager. There should be a "USB OK" message on the status bar at the bottom of evaluation program,
and the red LED should blink on the evaluation board, when the board is recognized. In case the board is
not recognized, check the USB address from Windows Control Panel. The USB address should always be
less than or equal to 9 (from COM1 to COM9) (see Appendix D). Also switching to another USB port might
solve the issue.
A connector for external VDD and VEN is also provided. I2C communication can be controlled from an
external source using pin headers. Test point for all of the signals is provided.
3.2 Evaluation Hardware
The LP5562 evaluation hardware consists basically of two sections:
LP5562 and the application components: LEDs and input capacitor
MSP430 microcontroller and its support components

By default the LP5562 is controlled by the MSP430 microcontroller via USB. VDD and VEN voltages come
from USB, and the I2C traffic is controlled with microcontroller. The evaluation hardware may also be
externally controlled. The VDD and VEN can be fed externally via a connector and with jumper selection.
The I2C traffic, EN-pin, and CLK_32K control can be changed from MSP430 control to external control
using a pin header. LED driver control can be changed from RGB LED to WLED LEDs, except for the W-
LED channel. The pin header enables current measurement to the LED drivers. Device I2C address
selection can also be changed with a pin header. For each device pin, there exists a test point (header).
3.3 Evaluation Software
The LP5562 evaluation software helps user to control the evaluation hardware connected to the computer.
The evaluation software consists of three sections: tab selection, register selection and register control
section. In the tab selection user can switch between Manual, Program and History tabs. In the left-hand
side of the evaluation program the register view (see Figure 3-2) is always visible. From this view user can
see the register addresses, register names and register values. User can select the register that needs to
be changed. Selected register is marked with red X beside the register value. When user selects the
register, the selected register can be viewed in detail at the bottom of the evaluation software (see
Figure 3-3). This view tells the register address, register name, register default value, register bits and
current register value. User can also read and write the register bits by pushing the RD-button (read) and
Write-button (write).

Running
When downloading a program into the LP5562, user must first select the file to be downloaded. Pushing
the leftmost button over the "Master control" section Open file dialog opens (Figure 3-6. User can select
the program code (a hex-file) (see Figure 3-7) and push the Open button. After "Open file" dialog
disappears, push the Download program into the LP5562 –button (middle button). This automatically sets
the Program Execution Engines into right modes and the program gets written into SRAM memory. Also,
the Program Execution Engine Program Counters are set to 0. The correct I2C writes for engine modes,
and program counters can be seen from the History tab, but the SRAM writes are not visible there. Note
that setting the "Load" mode from the Master control section does not download the opened code. If user
wants to use the Master control Load option, the "Code Memory" map in Manual tab must be used.

In the Program tab there is Master control for all 3 engines and separate controls for each engine. The
radio buttons (Disable, Load, Run, Direct Control) control the engine operation mode. The four buttons
(Stop, Step, Execute Command and Free Run) control the engine execution states. See tables Table 3-1
and Table 3-2 for operation mode and execution state descriptions.
These same buttons are also available for each individual engine, thus enabling individual control of each
engine; i.e., each engine can be run separately. In the same section as the individual engine controls
there is a checkbox. When this box is checked the Master control affects that engine. If it is unchecked,
the Master control has no effect on that engine.
If user wants to write a program directly to SRAM memory the engine must be set to Load mode. The
writes to the SRAM memory are done from the Manual tab. When the address is selected from the table,
the data is displayed in the indicator's Address and Data. These can be edited, and the value is updated
by pressing the "Update" button. Note that this Update does not write the program memory. The program
memory is written by pushing "Write memory" button. With the "Read memory" button, program memory is
read to the table. Note that the program memory addresses does not comply with the SRAM I2C
addresses.

3.3.3 History Tab
The "History" tab (see Figure 3-12) provides information on the I2C writes used to configure/control the
LP5562 device. This is a good way of debugging or finding out what writes/reads have been done.
However, the history tab does not record the SRAM memory writes when downloading a program.
Figure 3-12. History Tab
3.4 Command Compiler
A command compiler is used to write LED sequences for the LP5562. The command compiler is a simple-
to-use Windows program with a graphic-user interface.
User can write his own memory files by using command compiler’s editor or any text editor (file must have
.src extension). Command compiler translates ASCII memory files into binary file (.bin), or hex files (.hex
and .he2). In the "Format" menu user can select between .bin, .he2 and .hex formats. Evaluation software
uses .hex format, but .bin and .he2 formats can be used for user's own applications. To start command
compiler, double-click the compiler icon (compiler.exe). Source file can be opened from File/Open menu.
Source files have .src extension. When source tab has been selected, the source code is visible and can
be modified, compiled, and saved. File must be created first to be able to edit it using the File/New menu
or, for example, to open some demo sequence, and save with another name. Below is the syntax and
explanation for command compiler commands. Program can be compiled to binary or hex formats with
compile menu. After compilation, command list can be seen by clicking "List" tab. Compilation generates
binary/hex/he2 file and list file. Compiled file has 16 commands for each channel for a total of 48
commands. File represents the whole SRAM program memory content.

3.4.1 Syntax
Comment – Line starting with “#” symbol. Example: # engine 1 section start
Sections – Engine1, engine2 or engine3 section starts with: .ENGINE1, .ENGINE2 or .ENGINE3.
Example: .ENGINE1
Labels – Any words with colon (:) as ending symbol. Example: label1:
3.4.2 Commands
Ramp: Ramp command generates a PWM ramp from current value. Ramp command has two
parameters – first is time in milliseconds (floating point format, maximum execution time tMAX = (1000 ms x
number of steps) - 1 ms) and second is number of steps (positive or negative, integer 2-128) separated
with comma. Example: ramp 20.5,6
Wait: With wait command program execution stops for time defined. Command has one parameter, time in
milliseconds (floating point format, maximum 999). Example: wait 50.5
Branch: Branch command loads step number to program counter. Branch command has two parameters,
loop counter (integer 0-63, 0 means infinite loop) and label separated with comma. Label must be
predefined before using in a branch command. The following example loops 5 times commands between
label1 and branch command: Example: label1: … branch 5,label1
Set_PWM: Set_pwm command sets PWM output value. Command has one parameter, PWM value
(integer 0-255). Example: set_pwm 23
Start: (Go to) Start command resets program counter and continues executing from the beginning of
section. No parameters used. Example: start
Trigger: Trigger command sets wait or send trigger. Command has two parameters, wait trigger channel
and send trigger channel. Channels are defined as: 1 = engine1, 2 = engine2, 3 = engine3. Examples:
trigger s1 => (Send trigger to engine1); trigger s2 => (Send trigger to engine2); trigger s3 => (Send trigger
to engine3); trigger s23 => (Send trigger to engine2 and engine3); trigger w1 => (Wait trigger from
engine1); trigger s1,w3 => (Send trigger to engine1 and wait trigger from engine3)
End: End command ends program execution. Also interrupt signal can be send or program counter can be
reset. Command can have up to two parameters. I = interrupt send, R = reset program counter. Examples:
end I; end R; end R,I; end I,R (same as earlier); end
3.4.3 Errors
If there is an error during compilation an error message is generated. Error messages are as follows:
1 = engine section error
2 = syntax error
3 = ramp parameter error
4 = SRAM memory overflow
6 = ramp step error
7 = branch error
9 = set_pwm parameter error
11 = wait parameter error

Command Compiler
3.4.4 Files
There are five files that can be created with the command compiler. The source file has .src extension and
is in source code format. During compilation listing file with .lst extension is created always. Also binary file
with .bin extension or hexadecimal files with .hex and .he2 extension can be generated during compilation.
What file from *.bin, *.hex or *.he2 is compiled can be selected from Format menu. File name for the list,
binary, and hexadecimal files is the same as for source file name.
List-file (*.lst) contains command address, command in hex format and commands in compiler format.
This format can be seen also in evaluation program Program tab, when the code is loaded into the
LP5562. Below is an example of a beginning from a program code list file:
1. ===blink_3s_wait.lst===
2. 1 # engine 1 section start
3. 2 00 .ENGINE1
4. 3 loop1:
5. 4 00 40FF set_pwm 255
6. 5 01 4D00 wait 200
7. 6 02 01F2 ramp 5, -115
Binary-file (*.bin) contains all commands in a 16-bit binary format. Each command is on its own row.
Below is an example of a beginning from a program code binary file (8 commands visible):
1. 0100000011111111
2. 0100110100000000

Programming Considerations
B.1 Wait/Ramp Command
The ramp command generates either an increasing or decreasing PWM ramp, for which execution time
and number of steps can be defined. In one ramp command PWM value can be incremented or
decremented up to 128 steps from the present PWM value. The maximum PWM value is 255 which
means the engine's mapped current source(s) is constantly active. Ramp command maximum execution
time tMAX = (1000 ms x number of steps) - 1 ms.
Figure B-1 illustrates ramp and wait command usage. The program has been made with the command
compiler. The first ramp command increases PWM value from 0 to 100 in 150 ms. The second ramp
command will increase PWM value from 100 to 200 in 150 ms. PWM value is kept constant during the
next 300 ms wait cycle. Program then continues by ramping down PWM from 200 to 100 in 50 ms. During
the 450 ms wait cycle PWM value is kept constant, and the last command decreases PWM value from
100 to 0 during 100 ms.
Figure B-1. Ramp and Wait Command Example
By combining the ramp and wait commands the number of program commands can be reduced.Figure B-
2illustrates this situation. Ramp begins from PWM value 231 and saturates to 255 in 100 ms. After PWM
is saturated to maximum, ramp command changes to wait command for the rest 450 ms. Falling ramp
saturates similar way to 0 PWM value. After the saturation, the rest of the command execution will be wait
time.

Wait/Ramp Command
Figure B-2. Combined Ramp and Wait Command Example
Wait command maximum time is 999 ms on the command compiler; if longer wait time is required, then
branching (looping) can be used. Branch command is explained in this application note. Also ramp
command can produce the desired wait time if PWM level during wait cycle is either 0 or 255. Ramp
command maximum execution time tMAX = (1000 ms x number of steps) - 1 ms on the command compiler,
so maximum wait time with ramp command is 127 999 ms. On Figure B-3, PWM is first set to 255, and
1200 ms wait cycle is produced with a ramp command that increases PWM level by 127 in 1200 ms.
Since PWM is already at maximum, this command will only produce wait time. Similarly, falling ramp can
be used as a wait command if PWM level is 0.

B.2 Set PWM Command
Set_pwm command adjusts the PWM level with 8-bit control from 0 to 255. PWM level is adjusted to new
value in 0.488 ms (typ.).
B.3 Go-To-Start Command
Go-to-start command resets program counter, and program execution will be started from the beginning of
the program. Go-to-start can be interpreted as an infinite loop. By default, all program memory locations
are reset to zeros, which implies go-to-start command. In command compiler syntax this command is
Start. If program memory is fully occupied, and last command is ramp, wait, set_pwm or trigger, program
execution will be continued from the beginning of the program.
B.4 Branch Command
Branch command can be used to loop certain sequences in program. Figure B-4 illustrates branch
command. Program ramps up PWM level from 0 to 127 in 200 ms. PWM level is kept at a constant 200
ms, then ramped down to 0 in 200 ms. PWM is kept at 0 during the next 500 ms. The whole sequence is
executed 6 times. Loop start location is defined with label (loop1).

Figure B-4. Branch Command Example
The maximum loop count is 63 in one branch command, but the LP5562 supports loop inside loop i.e.
nested looping. Nested looping is illustrated in the following example. 1600 ms blinking cycle is repeated
10 times. LED is active 200 ms during the cycle and rest of the cycle 1400 ms is wait time. The program
has two loops loop1 and loop2. Loop1 repeats the whole sequence 10 times and loop2 creates 1400 ms
wait time.

B.5 End Command
End command stops program execution. There are two parameters which can be defined with an end
command: interrupt and reset. Interrupt can be used to notify the processor that program execution is at
the end. Status bits in register address 0CH inform which engine (1, 2, 3) has caused the interrupt. Status
bits will be cleared when status register 0CH is read. Reset parameter resets program counter to 0,
changes engine mode to hold from run mode, and sets PWM output to 0. If no parameters are defined,
engine will be changed to hold mode and PWM value will remain.
B.6 Trigger Command
Triggering is efficient way of controlling program execution between LP5562 engines (1,2,3). The following
example describes basic triggering concept. Each engine (1,2,3) have identical 100 ms LED pulse and
100 ms delay period after the pulse. Engine 1 begins the sequence by generating pulse and at the end
sends trigger to engine 2. Engine 2 continues program execution, and at the end of the program sends
trigger to engine 3 program.
Figure B-6. Basic Triggering Example
One engine can send multiple triggers in one command. Figure B-7 shows that engine 1 triggers both
engine 2 and 3. Engine 2 and 3 programs are identical.

Automatic Power-Save Functionality
C.1 Power Save With Engine Execution
Automatic power-save mode is enabled when PS_EN bit in register address 08H is 1. Almost all analog
blocks (including internal oscillator) are powered down in power save, if external clock is used. However, if
internal clock has been selected, only LED drivers are disabled during power save. Program execution
engine remains active during power-save mode.
During program execution the LP5562 can enter power save if there is no PWM activity in LED outputs
mapped to engines. To prevent short power-save sequences during program execution, the LP5562 has
command look-ahead filter. In every instruction cycle engine commands are analyzed, and if there is
sufficient time left with no PWM activity, device will enter power save. In power save program execution
continues uninterruptedly. When a command that requires PWM activity is executed, fast internal startup
sequence will be started automatically. Table C-1 describes commands and conditions that can activate
power save. All engines need to meet power-save condition in order to enable power save. Note that if a
LED output is mapped to the I2C register control and has PWM, it prevents power save even though
engine execution would allow power save.
Table C-1. Power-Save Condition With Operation Mode
LED controller operation mode Power save condition
(ENG1/ENG2/ENG3_MODE)
00b Disabled mode enables power save
01b Load program to SRAM prevents power save
Run program mode enables power save if there is no PWM activity and
10b command look ahead filter condition is met
11b Direct control mode enables power save if there is no PWM activity
Table C-2. Power-Save Condition With Commands
Command Power save condition
No PWM activity and current command wait time longer than 50 ms. If
Wait prescale = 1 then wait time needs to be longer than 80 ms. (see Figure C-1
and Figure C-4)
Ramp command PWM value reaches minimum 0 and current command
Ramp execution time left more than 50 ms. If prescale = 1 then time left needs to be
more than 80 ms (see Figure C-2)
Trigger No PWM activity during wait for trigger command execution (see Figure C-3)
End No PWM activity or Reset bit = 1 (see Figure C-3)
Enables power save if PWM set to 0 and next command generates at least 50
Set PWM ms wait
Other commands No effect to power save
