Low-Cost Versatile Smart Card Interface

The 73S8009R is a very low-cost level shifter, single smart card (ICC) interface IC. The device includes a level shifter interface between a 3.3V (typical) logic circuitry (host microcontroller) and an ISO 7816/EMV smart card. The 73S8009R is designed to provide full electrical compliance with ISO 7816-3, EMV4.1 (EMV2000), and GSM11-11 specifications.

In normal operating mode, for maximum designer flexibility, the host microcontroller is responsible for card activation and deactivation. The 73S8009R incorporates an ISO 7816-3 deactivation sequencer that controls the card signals in case of fault detection and card removal. Card presence and faults are reported to the host through an interrupt output. When the 73S8009R is ready to support a card with the selected voltage, a RDY signal informs the host it can initiate the card activation sequence.
