STFPC320 Front panel controller/driver with standby power management and real-time clock

The STFPC320 is designed to integrate the VFD driving, key-scan matrix, LED driving, infrared (IR) remote control decoding and real-time clock (RTC) into one integrated solution. All the functions are programmable using the I²C bus.

Low power consumption is achieved during standby operation. The STFPC320 provides the standby power management to the main chipset.

The STFPC320 is housed in a 52-pin PQFP package. The pin assignments and application circuit are optimized for an easy PCB layout and cost saving advantages.
