System-on-chip for EMV smartcard terminals

12 February 2003 DSP, Micros & Memory

TDK Semiconductor says its 73S1121F smartcard terminal controller integrates all the functionality for implementing a complete range of smartcard terminals for network access security, e-purse terminals, payphones, vending machines, and inexpensive POS applications. It includes an 8052 processor, a USB interface, two built-in smartcard interfaces with a dedicated hardware ISO7816 UART, multiple development software layers, extensive I/Os, 64 KB of Flash, 4 KB of user-RAM, a PIN pad interface, on a single chip. A low level Application Programming Interface (API) is provided for device control and a high level API includes protocol layers for both asynchronous cards and full-speed USB, plus PIN-management functions for security. With two built-in ISO7816/EMV smartcard interfaces the chip incorporates an intelligent 5x6 keyboard interface, a USB port, and additional I/Os to connect an external LCD driver. Also included are several analog inputs, reserved user I/O lines, and a GPIO port.
