NOTES:

47K

1) VDD = 2.7V to 5.5V DC.*

2) VPC = 4.75V(ISO)/4.85V(NDS) to 5.5V DC*

VDD

3) Required if external clock from uP is used.

R4

4) Required if crystal is used.

1K

Y1, C2 and C3 must be removed if external clock is used.

Card detection

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

switch is

normally open

fault voltage. Can be left open.

* Do not begin a NDS card session until VPC > 4.85V and VDD > VTH (VDD fault threshold)

Smart Card Connector

NDS, EMV & ISO7816=1uF

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.
