The STFPC320 is a complete front panel controller/driver with standby power management and real-time clock. All functions are programmable using the I2C bus. Low power consumption is achieved during standby operation. The STFPC320 provides the standby power management to the host.
The STFPC320 is an integrated front‑panel controller/driver that combines VFD driving, key‑scan matrix, LED driving, infrared remote‑control decoding and a real‑time clock. All functions are programmable via an I²C interface and it provides standby power management for the host chipset. The device is supplied in a 52‑pin PQFP package and operates from 3.3 V (VDD) down to –30 V (VSS).
The manual includes a block diagram, functional description, pin settings, command set, remote‑control protocol details, real‑time clock operation, electrical characteristics, mechanical data and revision history, providing all information needed to integrate and program the STFPC320 in applications such as VCRs, DVD recorders, home‑theatre systems and set‑top boxes.
