Dear all:
I want to use compact flash interface of PDA to design circuit.
For instance,I want to design a microprocessor(8051 or AVR or MSP)
I/O control circuit.
The circuit must has compact flash interface to connect to PDA,and
PDA can use uart method control the compact flash I/O.If you have
any relative data. Please help me.Thank you.

cf serial interface

I think that compact flash can not connect serially using UART. As far as i am concerned the Multimedia Cards and not compact flash cards do have serial interface (SPI) which is not quite compatible with UART interface.

What DO you want to use: Compact flash or MMC?

If you wish to control a compact flash then you can use BASCOM AVR ver 1.11.7.4. It is a basic compiler for AVR that supports Compact flash. For example you can write or read data with a single command like "DriveWriteSector" or "DriveReadSector"

You can get a demo version at www.mcselec.com

BUT if you wish to controll an MMC using SPI interface, i think that there is full documentation at sandisk's site: "Using the Multimedia Card is SPI mode with an 80c51 microcontroller" at

I hope i helped a little. You can ask me
 
can not close flash interface

it's me again!

If you want specifications and time diagramms you can find them at

Are they correct?

I am realy need exactly what these links to.

Thank you.
 

Apparently the link has been changed. The new one is
