Flash emulators ...

Hello,

I'm looking for a flash emulator that will support the 64MB P33 NOR flash from Intel, part # RC48F4400P0TB00 (leaded) or PC48F4400P0TB00 (lead free).

By flash emulator, I mean an active device that can take the place of the flash part in circuit, uses RAM to emulate the flash memory, and has an ethernet or USB connection to make reloading the memory significantly faster than reprogramming a real flash device.

A few hours of searching hasn't turned up any viable leads. At this point, I'm concluding that no such device exists.

But, I'd love to be proven wrong.

OK, after searching high and low, I'm convinced that there are no large capacity flash emulators; devices of 64MB or larger.

Any thoughts on why has the flash emulator business failed to keep up with the increase in capacity of these devices?

Do you need to emulate flash writes in your particular application?

If you don't you could always wire up an adapter for a ROM emulator...

Why would anyone want one?

Hello, Mark,

That's a good clarification -- in fact, we don't need to emulate the programming / erase / other attributes of the flash device.

But in reality, I haven't found even ROM emulators that support devices as large as the P33. Do you know of any ROM emulators that support 64MB of RAM and have fast connections to a host (Wintel PC) development systems?

Thanks for any advice.

John

Hello,

In the past, people have used these devices to reduce the time required to program the flash device, when the flash device is modified frequently during software development.

In our case, the flash device is where our large application code is stored. By reducing the time required to reprogram this device from, say, 10 mins with a JTAG emulator to, say, 1 min to reload the code into a network or USB-accessible emulator, we speed up our edit-compile-debug cycle.

In the past, there was a pretty good industry in these devices, but it's possible that other changes in the embedded space have reduced their utility.

Thanks,

John

one?

Im not so sure about that, Ive certainly used eprom emulators in that way but then they were not reprogrammable in system. You have a big sytem and so could just use ram instead of flash.

I'm using one atm, but it's the customer's and not mine, so I'm not even sure how large the ROM it's emulating is! But according to the site, you can emulate up to 4Gbit devices...

Mark,

Thanks for the link. This seems to be spot-on.

I'll follow up with what I find out, for the record if nothing else.

Hello Frank,

I did speak with PromICE. They didn't have a device of the capacity we needed, but they were checking into some devices they did previously under some other kind of contract to another manufacturer.

The person I spoke with indicated he would be following up, but I haven't heard back from him yet. I'm not highly optimistic about PromICE right now ...

Thanks for your help.
