APPLICATION NOTE 4418
IC Interface Connects Compact Flash Card to Microcontroller
By: Fons Janssen


Abstract: This application note explains how to use an IC I/O extender to connect a compact-flash (CF) card
to the IC interface of a microcontroller. The software commands for reading and writing data are explained.
The MAX7311 I/O port extender is featured in the design circuit.

This design idea appeared in the September 1, 2006 issue of EDN magazine.

Data logging usually requires considerable memory for storing the measured data, especially when the number
of monitored channels is large. As a furthe……
