x MATRIX LED DRIVER DESCRIPTION The ISFL77 is a general purpose LEDs matrix driver with / cycle rate. The device can be programmed via an IC compatible interface. Each LED can be dimmed individually with 8-bit PWM data which allowing 6 steps of linear dimming. ISFL77 features Auto Breathing Modes which are noted as ABM-, ABM- and ABM-. For each Auto Breathing Mode, there are timing characters which include current rising / holding / falling / off time and loop characters which include Loop-Beginning / Loop-Ending / Loop-Times. Every LED can be configured to be any Auto Breathing Mode or PWM mode individually. FEATURES Supply voltage range from.7v to.v Programmable (8 RGBs) matrix size with de-ghost function Auto Breath Modes and PWM Mode Auto breath offers 8 steps gamma current, interrupt and state look up registers 6 steps global current setting Individual PWM control 6 steps Individual open and short error detect function QFN-0 (6mm 6mm) package RECOMMENDED EQUIPMENT.0V, A power supply ABSOLUTE MAXIMUM RATINGS.V power supply Caution: Do not exceed the conditions listed above, otherwise the board will be damaged. PROCEDURE The ISFL7 evaluation board is fully assembled and tested. Follow the steps listed below to verify board operation. Caution: Do not turn on the power supply until all connections are completed. ) Short J to connect VO and. ) Short J to connect P and U. ) Connect the VDC power to the connector (J&J). ) Turn on the power supply/plug in the Micro USB Pay attention to the supply current. If the current exceeds A, please check for circuit fault.

x MATRIX LED DRIVER EVALUATION BOARD OPERATION The ISFL77 evaluation board has three animation display modes. Press K to switch configurations. ) Line- rotate animation ) Money animation ) Butterfly animation ) All led turn on Note: ISFL77 solely controls the FxLED function on the evaluation board. SOFTWARE CONTROL J default setting is closed (short). If it is set to open, the U (LDO) will stop working and all the V, including the supply of MCU will be cut off, all the MCU's IO will be high impedance (open-drain) and external control is allowed. The ISFL77 can set its IC bus interface logic threshold based on the voltage on the pin. An external voltage in the range of.8v can be applied after removing (open) the J jumper. The board comes with J default setting closed (short). If it is set to open, the user can connect an external voltage supply, the external voltage is recommended to equal to ex-iic s high logic. Follow the steps listed below for external control. ) Open J to disconnect the power of U, disable the V0 (.0V). ) Open J to disconnect the to V0, and connect an external MCU to. ) Pull-up the SDB to. ) Connect the VDC power to the connector (J&J). ) Turn on the power supply/plug in the Micro USB Pay attention to the supply current. If the current exceeds A, please check for circuit fault. 6) Start external IIC control. Caution: If J is closed (shorted), user can t connect the user s MCU to directly, otherwise the user s MCU (maybe.8v) will connect to evaluation bard s (.0V) and maybe damaged.
