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.

Notice: The ML69240-C49 was designed to conform to ISO/IEC 7816-3 second edition 1997 with the following limitations: 1) The ML69240-C49 operates under Class A (5V) only, hence the class indicator in the ATR is received but not examined. 2) The asynchronous clock provided is fixed at 3.5795 MHz and Clock stop is not supported. 3) The supported ICC data rate is fixed at 9600 baud. It is recommended that the host to IFD communication speed be kept at 19200 baud and above to avoid under or overruns. 4) The Vpp line is kept in the Pause state once the card is powered up under asynchronous conditions, but does not supply any programming power. 5) The ML69240-C49 uses the host to buffer the data, hence it supports the maximum block size, but requires the host to participate in error recovery and retransmission of T=1 blocks as well as the reception of blocks with the chaining flag set. 6) The NAD is fixed at 0. As OKI cannot guarantee proper operation with any type of IC-card, we strongly recommend to evaluate the functional and electrical characteristics in combination with the possible ICcards before design-in.
