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.

(Note: Software developed by Applied Card Technologies Ltd)

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 IC-
cards before design-in.
