Part number:73S8024RN
Function:Interface and Interconnect
Description:Low-Cost Smart Card Interface The 73S8024RN is a single smart card interface IC, compliant to the electrical requirements of ISO 7816-3, EMV 4.0, and NDS 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, VCC card voltage monitoring, and power system supplies voltage monitoring and die overheating. The 73S8024RN generates the smart card power supply (VCC) with an LDO regulator. Consequently, the IC requires two distinct power supplies, whereas the 73S8024C and 73S8023C implement a step-up converter (utilizing an external inductor), and the IC requires a single +3.3V standard power supply. The three devices are firmware compatible with the industry-standard TDA8024, while offering significant advantages in terms of both performance and cost. The 73S8023C is also firmware compatible with the former TDA8002 circuit, widely used in POS and payment terminals.
