The 73S8024C is a single smart card interface IC, compliant to the electrical requirements of ISO 7816-3 and EMV 4.0 electrical specifications. The host processor handles handling the ISO 7816 UART and associated protocol layers. The 73S802x chip family has a card activation and deactivation state machine that can be managed by the host. Hardware fault detection includes smart card extraction, true card overcurrent, V_CC card voltage monitoring, and power system supplies voltage monitoring and die overheating. The 73S8024C implements a step-up converter (utilizing an external inductor), and the IC requires a single +3.3V standard power supply. The device is firmware compatible with the industry-standard TDA8024, while offering significant advantages in terms of both performance and cost.
