Flash emulators ...

Started by JSambrook October 13, 2006
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... Regards, -- Mark McDougall, Engineer Virtual Logic Pty Ltd, <http://www.vl.com.au> 21-25 King St, Rockdale, 2216 Ph: +612-9599-3255 Fax: +612-9599-3266

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

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.

<http://www.emutec.com/pjetmain.html> 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...
