64-pin plastic QFP (14

× 14 mm)

µPD780031AYGC-×××-AB8, 780032AYGC-×××-AB8, 780033AYGC-×××-AB8, 780034AYGC-×××-AB8

•

64-pin plastic LQFP (12

× 12 mm)

µPD780031AYGK-×××-8A8, 780032AYGK-×××-8A8, 780033AYGK-×××-8A8, 780034AYGK-×××-8A8

Cautions 1. Connect the IC (Internally Connected) pin directly to VSS0 or VSS1.

2. Connect the AVSS pin to VSS0.

Remark

When the

µPD780031AY, 780032AY, 780033AY, and 780034AY are used in applications where the

noise generated inside the microcontroller needs to be reduced, the implementation of noise reduction

measures, such as supplying voltage to VDD0 and VDD1 individually and connecting VSS0 and VSS1 to

different ground lines, is recommended.
