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.
FEATURES
• LCD controller/driver
: Can display up to 75 segments.
1/3 duty, 1/3 bias, frame frequency: 325.5 Hz
• Key scan circuit
: Can read up to 30 (5 × 6) keys.
• LED output
: 1 pin
• 3-wire serial communication mode : CLOCK, DATA, and LOAD pins
• Supply voltage
: VDD = 4.5 to 5.5 V
• System clock
: fX = 8 MHz

2. CONFIGURATION OF KEY MATRIX
2.1 Layout of Key Matrix
The µPD17202AGF-011 can be used to configure a key matrix of up to 30 keys, KEY0 through KEY29, by using
the KS0 through KS4 pins (key source pins) and K0 through K5 pins (key return pins).
Keys KEY0 through KEY29 are allocated as shown below. The details of each key can be set arbitrarily.
