STFPC320 - Front panel controller/driver

General Description

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.

Key Features

  • IC front panel VFD controller driver Standby power management to the host 3.3 V (VDD) and down to -30 V (VSS) supply for the IC IR remote control decoder Multiple display modes (12 seg. and 16 digits to 20 seg and 8 digits) High voltage outputs (VDD - 33.3 V max) No additional external resistors required for driver outputs (P-CH. open drain + pull-down resistor outputs) Key scanning (up to 12 x 2 matrix = 24 keys) LED ports (4 channels 20 mA max each) S.
