General Description
The ML69240-C49 can control two sockets for ISO7816-3 IC-cards. It is based on an 80C51-
type 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.
