306 DOTS MATRIX LED DRIVER DESCRIPTION RECOMMENDED EQUIPMENT The IS31FL3742 is a general purpose 306 LED 5.0V, 2A power supply Matrix programmed via an I2C compatible interface. Each LED can be dimmed individually with 8-bit PWM ABSOLUTE MAXIMUM RATINGS data and 8-bit scaling data which allowing 256 steps of linear PWM dimming and 256 steps of DC current 5.5V power supply adjustable level. Caution: Do not exceed the conditions listed above, otherwise Additionally each LED open and short state can be the board will be damaged. detected, IS31FL3742 store the open or short information in Open-Short Registers. The Open-Short Registers allowing MCU to read out via I2C compatible PROCEDURE interface. Inform MCU whether there are LEDs open or The IS31FL3742 evaluation board is fully assembled short and the locations of open or short LEDs. and tested. Follow the steps listed below to verify board operation. FEATURES Caution: Do not turn on the power supply until all connections are completed. Supply voltage range from 2.7V to 5.5V 30 Current Sink 9 SW matrix size: drive up to 1) Short J4 and EXT (Open=Ext control). 180 LEDs or 60 RGBs 2) Short J1 and SDA (Connect SDA to U2). Individual 256 PWM control steps 3) Short J2 and SCL (Connect SCL to U2). Individual 256 DC current steps 4) Short J3 and SDB (Connect SDB to U2). Global 255 current setting 5) Turn on the power supply/Plug in the Micro USB SDB rising edge reset I2C module Pay attention to the supply current. If the current exceeds 1.5A, please check for circuit fault. Interrupt and state lookup registers Individual open and short error detect function EVALUATION BOARD OPERATION De-ghost QFN-48 (6mm6mm) package The IS31FL3742 evaluation board has three animation display modes. Press K1 to switch QUICK START configurations. Rainbow wave 1 1) Rainbow wave 2 2) Rain 3) 4) Visor Note: IS31FL3742 solely controls the FxLED function on the evaluation board.

Integrated Silicon Solution, Inc. www.issi.com 1 Rev. A, 03/09/2018 306 DOTS MATRIX LED DRIVER SOFTWARE SUPPORT firmware updates. First download the latest Arduino Integrated Development Environment IDE (1.6.12 or J4 and 3V default setting is closed (jumper on). If it is greater) from www.arduino.cc/en/Main/Software. Also open (no jumper), the on-board MCU will configure its download the Wire.h library from own I2C/SDB/ADDR pins to High Impedance status www.arduino.cc/en/reference/wire and verify that so an external source can driver the I2C/SDB signals pgmspace.h is in the directory program to control the IS31FL3742 LED driver. Files(x86)/Arduino/hardware/tools/avr/avr/include/avr /. Then download the latest IS31FL3742 test firmware The ADDR pin is pulled low via R34 setting the device (sketch) from the ISSI website address of IS31FL3742 to 0x60.
