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. 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.
