STMicroelectronics STLED325 LED Controller/Driver Datasheet
The STLED325 is a compact LED controller/driver designed to interface microprocessors to LED displays via a serial I2C interface. It drives LEDs in a common anode configuration and supports up to 40 discrete LEDs in an 8-segment/5-digit setup. The device integrates keyscanning for an 8x2 key matrix, standby power management for the host, and a low-power real-time clock (RTC).
