Smart Card Reader ICs 44-Pin QFN

The Teridian Semiconductor Corporation 73S1209 is a versatile and economical CMOS System-on-Chip device intended for smart card reader applications. More generally, it is suitable anywhere a UART to ISO-7816 / EMV bridge function is needed. The circuit is built around an 80515 high-performance core; it features primarily an ISO-7816 / EMV interface and a generic asynchronous serial interface. Delivered with turnkey Teridian embedded firmware, it 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 solution is scalable, thanks to a built-in I2 C interface that allows to drive external electrical smart card interfaces such as Teridian 73S8010R/C ICs. This makes the solution immediately able to support multi-card slots or multi-SAM architectures. In addition, the 73S1209 features a 5x6 PINpad interface, 9 user I/Os, 2 LED outputs (programmable current), multiple interrupt options and an analog voltage input (for DC voltage monitoring such as battery level detection) that make it suitable for low-cost PINpad reader devices. The 80515 CPU core instruction set is compatible with the industry standard 8051, while offering one clock-cycle per instruction processing power (most instructions). With a CPU clock running up to 24MHz, it results in up to 24MIPS available that meets the requirements of various encryption needs such as AES, DES / 3-DES and even RSA (for PIN encryption for instance). The circuit requires a single 6MHz to 12MHz crystal. The respective 73S1209 embedded memories are 32KB Flash program memory, 2KB user XRAM memory, and 256B IRAM memory. Dedicated FIFOs for the ISO7816 UART are independent from the user XRAM and IRAM. Alternatively to the turnkey firmware offered by Teridian, customers can develop their own embedded firmware directly within their application or using Teridian 73S1209F Evaluation Board through a JTAG-like interface. Overall, the Teridian 73S1209 IC requires 2 distinct power supply voltages to operate normally with full support of all smart card voltages, 1.8V, 3V and 5V. The digital power supply VDD requires a 2.7V to 3.6V voltage, and the analog power supply VPC requires typically a 4.75V to 6.0V. While the VDD is used to power up the CPU core and the digital functions of the IC, the VPC voltage is used to supply the proper VCC voltage to the smart card interface: The chip incorporates an low drop-out linear voltage regulator that generates the smart card power-supply VCC from the power supply source VPC. Embedded Flash memory is in-system programmable and lockable by means of on-silicon fuses. This makes the 73S1209 suitable for both development and production phases. Teridian Semiconductor Corporation offers with its 73S1209 a very comprehensive set of software libraries for EMV. Refer to the 73S12xxF Software User’s Guide for a complete description of the Application Programming Interface (API Libraries) and related Software modules. A complete array of development and programming tools, libraries and demonstration boards enable rapid development and certification of readers that meet most demanding smart card standards
