Interfacing the DS5250 with a magnetic stripe card reader

This application note explains how magnetic stripe card reading and decoding can easily be implemented on the DS5250 secure microcontroller. The article also demonstrates how applications can be developed that combine magnetic stripe card reading functions with the higher level security and cryptographic functions of a secure MCU. This example uses the DS5250 evaluation kit to interface to a magnetic stripe card reader. Source code is provided, and can easily be ported to any of Maxim's other 8051-based MCUs.
