ML69240-C49
Intelligent Microcontroller Driven Dual Smartcard Reader
Designed developed Applied Card Technologies association with Taiko Electronics
General Description
ML69240-C49 control sockets ISO7816-3 IC-cards. based 80C51type microcontroller-core. Multiple asynchronous synchronous protocols supported. addition, other peripheral modules like keypad LC-Display connected controlled ML69240-C49. Interfacing with host done simple commands that transferred over RS232 serial port. simple structure command full support peripheral components, software hardware design card reader system based ML69240-C49 easy realise.

Notice: ML69240-C49 designed conform ISO/IEC 7816-3 second edition 1997 with following limitations: ML69240-C49 operates under Class (5V) only, hence class indicator received examined. asynchronous clock provided fixed 3.5795 Clock stop supported. supported data rate fixed 9600 baud. recommended that host communication speed kept 19200 baud above avoid under overruns. line kept Pause state once card powered under asynchronous conditions, does supply programming power. ML69240-C49 uses host buffer data, hence supports maximum block size, requires host participate error recovery retransmission blocks well reception blocks with chaining flag set. fixed cannot guarantee proper operation with type IC-card, strongly recommend evaluate functional electrical characteristics combination with possible ICcards before design-in.
