10. PCB LAYOUT GUIDE FOR HEAVY LOADING APPLICATION

To avoid the unexpected noise, which may end up with incorrect CPU operations, the following cares must be exercised while designing a

PCB layout:

1.

Bond all VDD and VSS pins out.

2.

The 0.1uF capacitor placed between VDD and VSS must be as close as possible to IC itself.

3.

Power routes are as independent as possible.

10.1. The PCB layout examples are given as follows

(For GPC3680A~ GPC3256A, GPC3340B~ GPC33256B)
