73S1217F

The respective 73S1217F embedded memories are; 64KB Flash program memory, 2KB user XRAM memory, and 256B IRAM memory. On top of these memories are added independent FIFOs dedicated to the ISO7816 UART and to the USB interface. The chip incorporates an inductor-based DC-DC converter that generates all the necessary voltages to the various 73S1217F function blocks (smart card interface, digital core, etc.) from any of two distinct power supply sources: The +5V USB bus (V BUS , 4.4V to 6.5V), or a main battery (V BAT , 4.0V to 6.5V). The chip automatically powers-up the DC-DC converter with V BUS if it is present, or uses V BAT as the supply input. The Teridian Semiconductor Corporation 73S1217F 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 - slave) and a 5x6 PINpad interface. Additional features include 8 user I/Os, multiple interrupt options and an analog voltage input (for DC voltage monitoring such as battery level detection). Other built-in interfaces include an asynchronous serial and an I2C interface. The System-on-Chip is built around an 80515 high- performance core. The feature and instruction set of the 73S1217F is compatible with the industry standard 8051, while offering one clock-cycle per instruction processing power (most instructions). The OFF mode can be alternatively initiated from the controller (firmware action instead of ON/OFF switch). In OFF mode, the circuit of the 73S1217F typically draws less than 1A, which makes it ideal for applications where battery life must be maximized. 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. With a CPU clock running up to 24MHz, it results in up to 20MIPS 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 6 to 12 MHz crystal. An optional 32kHz crystal can be connected to a sub-system oscillator with a real-time- clock counter to enable stand-alone applications to access an RTC value. Alternatively, the pin V PC can support a wider power supply input range (2.7V to 6.5V), when using a single system supply source. Wake-up of the controller upon USB cable insertion is supported. Embedded Flash memory is in-system programmable and lockable by means of on-silicon fuses. This makes the Teridian 73S1217F suitable for both development and production phases. Teridian Semiconductor Corporation of the 73S1217F offers with its 73S1217F a very comprehensive set of software libraries, including the smart card and USB protocol layers that are pre-approved against USB, Microsoft WHQL and EMV, as well as a CCID reference design. Refer to the Teridian Semiconductor Corporation 73S12xxF Software User's Guide for a complete description of the Application Programming Interface (API Libraries) and related Software modules. 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).
