Data Sheet U14126EJ1V0DS00

PIN CONFIGURATION (Top View)

• 80-pin plastic QFP (14

× 20 mm, 0.8 pitch)

µPD178023GF-×××-3B9, 178024GF-×××-3B9

Cautions 1. Directly connect the IC (Internally Connected) to GND.

2. Keep the voltage at VDDPORT and VDDPLL at the same voltage as VDD.

3. Keep the voltage at GNDPORT and GNDPLL at the same voltage as GND.

4. Connect each of the REGOSC and REGCPU pins to GND via 0.1-

µF capacitor.
