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
