NOTES:
1) VDD = 2.7V to 5.5V DC.*
NDS, EMV & ISO7816=1uF
Low ESR (<100mohms) C1
should be placed near the SC
connecter contact
2) VPC = 4.75V(ISO)/4.85V(NDS) to 5.5V DC*
3) Required if external clock from uP is used.
4) Required if crystal is used.

1K
Y1, C2 and C3 must be removed if external clock is used.
5) R1 and R3 are external resistors that adjust the VDD
fault voltage. Can be left open.
Card detection
switch is
normally open
CLK track should be routed
far from RST, I/O, C4 and
C8.
* Do not begin a NDS card session until VPC > 4.85V and VDD > VTH (VDD fault threshold)
