73S1113F

    General Description

    The second member of the Teridian Semiconductor 73S11xx family of smart card terminal controllers, the 73S1113F, is a stripped down version of the full-featured 73S1121F. It shares the same digital platform (80C52 core, with 64kB of Flash program memory and 4kB of user XRAM data memory, ISO7816 UART). It features a single built-in ISO7816 / EMV smart card interface and a USB full-speed interface. Additionally, it has a man-machine interface with a 5×5 PIN-pad interface and 7 dedicated LCD I/Os. The 73S1113F is especially suitable for PC-connected applications for payment or identification.
