www.DataSheet4U.com Rev. 1.2, Aug. 2000 _____________________________________________________________________________________________ ML69240-C49 - Preliminary - _____________________________________________________________________________________________ Intelligent Microcontroller Driven Dual Smartcard Reader IC _____________________________________________________________________________________________ Designed and developed by Applied Card Technologies Ltd in association with Taiko Electronics _____________________________________________________________________________________________ General Description The ML69240-C49 can control two sockets for ISO7816-3 IC-cards. It is based on an 80C51type microcontroller-core. Multiple asynchronous and synchronous protocols are supported. In addition, other peripheral modules like keypad and LC-Display can be connected and controlled by ML69240-C49. Interfacing with the host is done via simple commands that are transferred over a RS232 serial port. Due to the simple structure of the command set and the full support of the peripheral components, the software and hardware design for a card reader system based on ML69240-C49 is easy to realise.
