NOTES:

1) VDD = 2.7V to 5.5V DC.

2) VPC = 4.75V to 5.5V DC

3) Required if external clock from uP is used.

4) Required if crystal is used.

5) R1 and R3 are external resistors that adjust the VDD

normally open

fault voltage. Can be left open.

Low ESR (<100mohms) C1

C1 should be placed near the SC

connecter contact

CLK track should be routed

far from RST, I/O, C4 and

C8.
