24-RGB MATRIX LED DRIVER DESCRIPTION RECOMMENDED EQUIPMENT The IS31FL3746A is a general purpose 18n (n=1~4) 5.0V, 2A power supply LED Matrix programmed via 1MHz I2C compatible interface. Each LED can be dimmed individually with ABSOLUTE MAXIMUM RATINGS 8-bit PWM data and 8-bit DC scaling (Color Calibration) data which allowing 256 steps of linear PWM dimming 5.5V power supply and 256 steps of DC current adjustable level. Caution: Do not exceed the conditions listed above, otherwise the board will be damaged. Additionally each LED open and short state can be detected, IS31FL3746A store the open or short information in Open-Short Registers. The Open-Short PROCEDURE Registers allowing MCU to read out via I2C compatible The IS31FL3746A evaluation board is fully assembled interface. Inform MCU whether there are LEDs open or and tested. Follow the steps listed below to verify short and the locations of open or short LEDs. board operation. Caution: Do not turn on the power supply until all connections FEATURES are completed. Supply voltage range: 2.7V to 5.5V 1) Connect Pin1 and Pin2 in JP6 to enable the 18 current sinks control of board MCU (default status). Support 18n (n=1~4) LED matrix configurations 2) Connect Pin2 and Pin3 in JP5 to connect the VIO Individual 256 PWM control steps to 3V. Individual 256 DC current steps 3) Connect Pin1 and Pin2 in JP1 (ADDR2) / JP2 Global 256 current steps (SDA) / JP3 (ADDR1) / JP4 (SCL). SDB rising edge reset I2C module 4) Connect the 5VDC power to VCC/GND of TP4, or 29kHz PWM frequency plug in the USB power input to micro-USB. 1MHz I2C-compatible interface 5) Turn on the power supply, pay attention to the State lookup registers supply current. If the current exceeds 1A, please Individual open and short error detect function check for circuit fault. De-Ghost QFN-32 (4mm4mm) package EVALUATION BOARD OPERATION QUICK START The IS31FL3746A evaluation board has three display modes. Press K1 to switch configurations: 1) (Default mode) Colors breathe change. 2) Rainbow. 3) Half cycle colors change. Note: IS31FL3746A solely controls the FxLED function on the evaluation board.

Lumissil Microsystems www.lumissil.com 1 Rev. B, 08/26/2019 24-RGB MATRIX LED DRIVER SOFTWARE SUPPORT The steps listed below are an example using the Arduino for external control. Pin1 and Pin2 of JP6 is default shorted. If the jumper is opened or move to Pin 2 and Pin 3, the on-board MCU The Arduino hardware consists of an Atmel microcontroller with a bootloader allowing quick will configure I2C pins and SDB pin to high impedance. External I2C and SDB signals can be connected to firmware updates. First download the latest Arduino Integrated Development Environment IDE (1.6.12 or TP4 (Above Lumissil Logo) to control the IS31FL3746A LED driver. greater) from www.arduino.cc/en/Main/Software. Also download the Wire.h library from www.arduino.cc/en/reference/wire and verify that pgmspace.h is in the directory program Files(x86)/Arduino/hardware/tools/avr/avr/include/avr /. Then download the latest IS31FL3746A test firmware (sketch) from the Lumissil website
