73S1210F

The circuit requires a single 6MHz to 12MHz crystal. The chip incorporates an inductor-based DC-DC converter that generates all the necessary voltages to the various 73S1210F function blocks (smart card interface, digital core, etc.)from any of two distinct power supply sources: the +5V bus (VBUS, 4.4 to 6.5V), or a main battery (VBAT, 4.0V to 6.5V). 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). Embedded Flash memory is in-system programmable and lockable by means of on-silicon fuses. This makes the 73S1210F suitable for both development and production phases. The chip automatically powers-up the DC- DC converter with VBUS if it is present, or uses VBAT as the supply input if VBUS is not present. Alternatively, the pin VPC can support a wider power supply input range (2.7V to 6.5V), when using a single system supply source. In OFF mode, the circuit typically draws less than 1A, which makes it ideal for applications where battery life must be maximized. The respective 73S1210F embedded memories are 32KB Flash program memory, 2KB user XRAM memory, and 256B IRAM memory. Dedicated FIFOs for the ISO 7816 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 73S1210F Evaluation Board through a JTAG-like interface. The 73S1210F is a versatile and economical CMOS System-on-Chip device intended for smart card reader applications. 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 In addition, the circuit features an ON/OFF mode which operates directly with an ON/OFF system switch: Any activity on the ON/OFF button is debounced internally and controls the power generation circuit accordingly, under the supervision of the firmware (OFF request / OFF acknowledgement at firmware level). The OFF mode of the 73S1210F can be alternatively initiated from the controller (firmware action instead of ON/OFF switch). C interface that allows to drive external electrical smart card interfaces such as Teridian 73S8010 ICs. This makes the solution immediately able to support multi-card slots or multi-SAM architectures. In addition, the 73S1210 features a 5x6 PINpad interface, 8 user I/Os, multiple interrupt options and an analog voltage input of the 73S1210F(for DC voltage monitoring such as battery level detection)that make it suitable for low-cost PINpad reader devices. Teridian Semiconductor Corporation offers with its 73S1210F 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.
