The STLED325 is a compact LED controller/driver that interfaces microprocessors to LED displays through a serial I2C interface. It drives LEDs connected in a common anode configuration and includes keyscanning for an 8 x 2 key matrix, which automatically scans and debounces a matrix of up to 16 switches. Furthermore, the STLED325 provides standby power management to the host. It also integrates a low-power, highly accurate RTC and a remote control decoder. All functions are programmable using the I2C bus. Low power consumption during standby.
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).
