The Teridian 73S8014R is a single smart card (ICC) interface circuit, firmware compatible with 8024-type devices for configurations where only asynchronous cards must be supported.
The 73S8014R Smart Card Interface IC from Teridian provides a cost‑effective solution for set‑top‑box and other conditional‑access applications. It integrates a low‑dropout regulator, card voltage selection (3 V/5 V) and full ISO‑7816‑3/EMV 4.0 compliance, reducing external component count.
Key features include a maximum card current of 65 mA, 6 kV ESD protection on the card pins, a 20‑pin SO package, and a wide operating temperature range of –40 °C to +85 °C. The device interfaces to a host processor via digital I/Os and provides an interrupt line for card presence and fault reporting.
