73S1215F 80515 System-on-Chip with USB, ISO 7816 / EMV, PINpad and More Simplifying System Integration™ www.DataSheet4U.com DATA SHEET December 2008 GENERAL 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 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 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.
