73S1215F Datasheet | Teridian Semiconductor

DESCRIPTION The 73S1215F is a versatile and economical CMOS System-on-Chip device intended for smart card reader applications. The circuit features an ISO 7816 / EMV interface, an USB 2.0 interface (full-speed 12Mbps device) and a 5x6 PINpad interface. Maximum design flexibility is supported with additional features such as 9 user I/Os, multiple interrupt options, up to 4 programmable current outputs (to drive external LEDs), and 1 analog voltage input (suitable for DC voltage monitoring such as battery level detection). Other built-in hardware interfaces include an 2 asynchronous serial UART and an I C interface. The System-on-Chip is built around an 80515 high performance core. Its feature and instruction set is patible 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 20 MIPS 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 crystal, which frequency can be between 6MHz and 12MHz. In addition, a 32768 Hz sub-system oscillator (optional) with an independent real-time-clock counter enables standalone applications to access an RTC value. The respective 73S1215F embedded memories are; 64KB Flash program memory, 2KB user XRAM memory, and 256B IRAM memory. In addition to these memories are independent FIFOs dedicated to the ISO7816 UART and to the USB interface. Overall, the 73S1215F offers a cost effective solution to implement hand-held PINpad smart card readers - USB connected, serial connected, standalone or bo - as well as turnkey smart ® card reader modules, USB or Express Card type. Embedded Flash memory is in-system programmable and lockable by means of on-silicon fuses. This makes the Teridian 73S1215F suitable for both development and production phases. Teridian Semiconductor Corporation offers with its 73S1215F a very...
