Sunnyvale, Calif. Oki Semiconductor’s new ML675050 ARM7TDMI-based Advantage Microcontroller for Smart Card reader/writers meets ISO-7816 and EMV (Europay, MasterCard, Visa) IC Card standards.
The 32-bit ARM7-based ML675050 provides designers of Smart Card applications with an MCU that has a comprehensive set of peripherals, a variety of serial interfaces, QVGA B/W STN LCD controller, full-speed USB host and device controllers with integrated PHY. The MCU also includes a Modulo Calculation Accelerator designed for enhancing RSA encryption/decryption. This accelerator achieves a performance increase of up to 10 times over execution of RSA software.
According to David Pelavin, senior director, logic business development, Oki Semiconductor, “ML675050 is the ideal solution for designers of Smart Card devices who need an off-the-shelf, low-cost 32-bit MCU that incorporates the latest encryption/decryption technology, as well as a robust set of peripherals to meet their design requirements.”
Smart Card technology is rapidly changing the way goods and services are acquired by consumers. In North America an increasing number of merchants and consumers are taking advantage of the speed and convenience Smart Card devices offer them when conducting transactions at retail and grocery stores, gas stations, restaurants, theaters, hospitals and clinics, and public transit systems. For merchants and other business owners, the implementation of Smart Card devices helps to increase revenues by lowering overhead costs, providing faster transaction times, and more convenience for consumers.
Among the features of the ML675050 is the 64 MHz ARM7TDMI core with 8 Kbytes of unified cache, the MCU’s Modulo Calculation Accelerator for enhancing RSA encryption/decryption and its random number generator. There are 16 Kbytes of RAM, 2 Kbytes of battery backup RAM for storing crypto-key data as well as full-speed USB host and device support. Serial interfaces include I2C (2 channel), SPI (2 channel), UART (2 channel) and SIO. Also packed into the unit is an 8-chanel, 12-bit A/D converter and and LCD controller with 10 Kbytes of frame buffer.
For details of the processor, see block diagram below.
Sample code for the ML675050 is available in ARM Development Suite and ARM RealView Development Suite formats. Additional sample code from IAR Systems will be available in the third quarter of 2006. The ML675050 is available now for $6.63 in quantities of 100,000.
