PRELIMINARY DATA SHEET

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.

Can read up to 30 (5 × 6) keys.

1 pin

•

Key scan circuit

LED output

3-wire serial communication mode : CLOCK, DATA, and LOAD pins

Supply voltage

System clock

V^DD= 4.5 to 5.5 V

f^X= 8 MHz
