Smart Card Reader 68-Pin QFN EP

<P>The 73S1210 is a versatile and economical CMOS System-on-Chip device intended for smart card reader applications. The circuit is built around an 80515 highperformance 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.</P> <P>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 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.</P> <P>In addition, the 73S1210 features a 5x6 PINpad interface, 8 user I/Os, 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.</P> <P>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).</P> <P>The circuit requires a single 6MHz to 12MHz crystal.</P> <P>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.</P> <P>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.</P> <P>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 chip automatically powers-up the DCDC 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.</P> <P>In OFF mode, the circuit typically draws less than 1µA, which makes it ideal for applications where battery life must be maximized.</P> <P>Embedded Flash memory is in-system programmable and lockable by means of on-silicon fuses. This makes the 73S1210 suitable for both development and production phases.</P> <P>Teridian Semiconductor Corporation offers with its 73S1210 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.</P> <P>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</P> <ul><li>80515 Core: <ul><li>1 clock cycle per instruction (most instructions)</li><li>CPU clocked up to 24MHz</li><li>32KB Flash memory (lockable)</li><li>2kB XRAM (User Data Memory)</li><li>256 byte IRAM</li><li>Hardware watchdog timer</li></ul></li><li>Oscillators: <ul><li>Single low-cost 6MHz to 12MHz crystal</li><li>An Internal PLL provides all the necessary clocks to each block of the system</li></ul></li><li>Interrupts: <ul><li>Standard 80C515 4-priority level structure</li><li>9 different sources of interrupt to the core</li></ul></li><li>Power Down Modes: <ul><li>2 standard 80C515 Power Down and IDLE modes</li><li>Sub-µA OFF mode</li><li>ON/OFF Main System Power Switch:</li><li>Input for an SPST momentary switch to ground</li></ul></li><li>Timers: <ul><li>(2) Standard 80C52 timers T0 and T1</li><li>(1) 16-bit timer</li></ul></li><li>Built-in ISO-7816 Card Interface: <ul><li>Linear regulator produces VCC for the card (1.8V, 3V or 5V)</li><li>Full compliance with EMV 4.1</li><li>Activation/Deactivation sequencers</li><li>Auxiliary I/O lines (C4 and C8 signals)</li><li>7kV ESD protection on all interface pins</li></ul></li><li>Communication with Smart Cards: <ul><li>ISO 7816 UART 9600 to 115kbps for T=0, T=1</li><li>(2) 2-Byte FIFOs for transmit and receive</li><li>Configured to drive multiple external Teridian 73S8010x interfaces (for multi-SAM architectures)</li></ul></li><li>Voltage Detection: <ul><li>Analog Input (detection range: 1.0V to 2.5V)</li></ul></li><li>Communication Interfaces: <ul><li>Full-duplex serial interface (1200 to 115kbps UART)</li><li>USB 2.0 Full Speed 12Mbps Interface, PC/SC compliant with 4 Endpoints:</li><li>Control (16B FIFO)</li><li>Interrupt IN (32B FIFO)</li><li>Bulk IN (128B FIFO)</li><li>Bulk OUT (128B FIFO)</li></ul></li><li>I2C Master Interface (400kbps)</li><li>Man-Machine Interface and I/Os: "<ul><li>6x5 Keyboard (hardware scanning, debouncing and scrambling)"</li><li>(8) User I/Os</li><li>Single programmable current output (LED)</li></ul></li><li>Operating Voltage: <ul><li>Single supply 2.7V to 6.5V operation (VPC)</li><li>5V supply (VBUS 4.4V to 5.5V) with or without battery back up operation (VBAT 4.0V to 6.5V)</li><li>Automated detection of voltage presence - Priority on VBUS over VBAT</li></ul></li><li>DC-DC Converter: <ul><li>Requires a single 10µH Inductor</li><li>3.3V / 20mA supply available for external circuits</li></ul></li><li>Operating Temperature: <ul><li>-40°C to 85°C</li></ul></li><li>Package: <ul><li>68-pin QFN, 44 pin QFN</li></ul></li></ul>
