STLED325 I²C interfaced LED controller with standby and RTC
The STLED325 is a compact LED controller/ driver that interfaces microprocessors to LED displays through serial I²C interface. It drives LEDs connected in common anode configuration and includes keyscanning for an 8 x 2 key matrix which automatically scans and de-bounces 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 mode is achieved.
The STLED325 controller/driver is ideal as a single peripheral device to interface the front panel display with a single-chip host IC like CPU.
