73S8009R-IM/F

Low Cost Versatile Smart Card Interface

Teridian Semiconductor Corporation 

73S8009R Data Sheet

DS_8009R_056

• 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
