The 73S1210F is a versatile and economical CMOS System-on-Chip device intended for smart card reader applications. It features primarily an ISO-7816 / EMV interface and a generic asynchronous serial interface. It is delivered with turnkey Teridian embedded firmware, which forms a ready-to-use smart card reader solution that can be seamlessly incorporated into any microprocessor-based system where a serial line is available.
The 73S1210F integrates an 80515 high‑performance core with a full ISO‑7816/EMV smart‑card interface, a 5×6 keypad, eight user I/Os, analog voltage detection and an on‑chip DC‑DC converter. It can be powered from either a 5 V bus or a battery and includes an ON/OFF switch with sub‑µA power‑down mode.
The device offers up to 24 MHz CPU clock (24 MIPS), 32 KB flash, 2 KB XRAM and 256 B IRAM, and is supplied in 68‑pin or 44‑pin QFN packages. Teridian provides turnkey firmware and a full set of EMV/ISO‑7816 software libraries for rapid development.
