Re: MPC850 and ATA/IDE

Hi,
I am looking for the solution that I can use ATA/IDE general hard disk

There are at least three easy and inexpensive ways people add ATA/IDE
to the 8xx processors for embedded systems:

	Connect to PCMCIA interface
	Use a simple CPLD between the processor bus and disk
	Program one of the UPMs to generate timing and then
		externally buffer the signals

 MPC860 or MPC821 CPU is used and Wind bond 83C553

It is a more difficult solution on the 850 because of the PCI bridge
(fewer
physical address lines).  It is also the most expensive in money, board
space and software.
