MOS INTEGRATED CIRCUIT
µPD17202AGF-011
4-BIT SINGLE-CHIP MICROCONTROLLER
WITH LCD CONTROLLER/DRIVER AND KEY SCAN CIRCUIT
FOR FPC (FRONT PANEL CONTROLLER)
The µPD17202AGF-011 is a CMOS microcontroller for the FPC (Front Panel Controller) of a car stereo system.
This microcontroller is housed in a 64-pin QFP and is provided with an LCD controller/driver and key scan circuit,
enabling the reduction of the amount of wiring between the front panel of the car stereo system and the master
microcontroller.
