System Controller Interface
Five signal images of the card signals
(RSTIN, CLKIN, IOUC, AUX1UC, AUX2UC)
Two inputs select card voltage (CMDVCC%,
CMDVCC#)
Two Interrupt outputs (OFF, RDY) inform the
system controller of card presence / faults
and the interface status
Chip select input (CS)
Power down input (PWRDN)
Regulator Power Supply (VPC):
Class A-B-C readers: 5V, 3V and 1.8V
cards: 4.75 V to 6.0 V
Digital Interface (VDD): 2.7 V to 3.6 V
6 kV ESD protection on the card interface
SO28 or QFN20 package
