73S8010C-IM/F

The 73S8010C-IM/F is a single smart card interface IC in 32 pin QFN package. It provides full electrical compliance with ISO-7816-3 and EMV 4.0 specifications. Interfacing with host is done through two wire I2C bus. Data exchange with card is managed from system controller using I/O line (and eventually the auxiliary I/O lines). An on-chip oscillator using an external crystal or connection to clock signals coming from system controller can generate card clock signal. The 73S8010C IC incorporates an ISO-7816-3 activation/deactivation sequencer that controls card signals. Level shifters drive card signals with selected card voltage (3V or 5V) coming from an internal DC to DC converter. The 73S8010C is a cost effective solution for any smart card reader application to be powered from single 2.7V to 3.6V power supply with its high efficiency DC to DC converter. Hardware support for auxiliary I/O lines, C4/C8 contacts is provided.
