STFPC320
Front panel controller/driver with standby Power management and real-time clock
General features

IC front panel VFD controller driver Standby power management to the host 3.3 (VDD) and down to -30V (VSS) supply for the IC IR remote control decoder (Philips, NEC, Thomson, Sony, Matsushita) Multiple display modes (12 Seg and 16 Digits to 20 Seg and 8 Digits) High voltage outputs (VDD - 33.3V max) No external resistors necessary 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 20mA max each) Serial I2C interface (SCL, SDA) communication protocol b Operating speed up to 400 kHz for I2C Programmable hotkeys for IR remote control command Programmable hotkeys for KEYSCAN command Low power consumption in standby mode Dimming circuit (8 steps) Real time clock (accuracy 25secs/month) Wake-up alarm Internal oscillator with external crystal for RTC Available in PQFP-52 package (0.65mm pitch)
PQFP-52

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 functions are programmable using the I2C bus. Low power consumption during standby operation is achieved. The STFPC320 provides the standby power management to the main chipset. STFPC320 is housed in a 52-pin PQFP package. Pin assignments and application circuit are optimized for easy PCB layout and cost saving advantages.

Applications

VCR DVD Recorder Home Theatre with Clock feature Set-top box and other applications that require a compact, integrated solution. HTiB (Home Theater in a Box) Personal Video Recorders (PVRs)

Order codes
Part number STFPC320 Temperature range -40 to 85 C Package PQFP-52 Packaging TBD
