73S8009R-IM/F

The 73S8009R-IM/F is a low cost versatile smart card interface in 20 pin QFN package. The device includes a level shifter interface between a 3.3V (typical) logic circuitry (host microcontroller) and an ISO-7816/EMV smart card. 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. Typical applications include set to p-box conditional access and pay-per-view, SIM card readers in DECT and GSM phones, GPRS, WIFI and VOIP devices, point of sales & transaction terminals and general purpose smart card readers.
