Coldfire v5e

[pslegg]

I hope that someone can help with some information about the Coldfire v5 and v5e.

 On the Atari forum there has been some discussion about whether a V5e could be used in place of a V4e CPU.

On page 6 of this document   https://www.nxp.com/files-static/training_pdf/29147_COLDFIRE_CORES_WBT.pdf

it says that the V5 is socket compatible with the V4.

Is there any further information about the V5 that might answer some basic questions ?

That document you list is describing CORES, which are not physical devices. They're designs that can be dropped into gate arrays, or (more likely) designed into custom chips with the right peripherals for a specific job, like being the chip at the heart of an HP printer, as Fang Li said. That document said "you can drop a V5E design in place of a V4E one".

But Freescale-then-NXP never bought out any mass-market chips based on the V5 design.

Even if they had it would be very unlikely that there would be pin-compatible V4 and V5 ones. Just compare the number of very different V1, V2, V3 and V4 chips they made.

Hi,

Actually ColdFire V5 product does not in chip market. Only HP company is using special V5 chips in the laser printer.We did not release V5 product in mass market. So to disscuss the V5 here is no meaning.

Someone said that 400MHz V5e versions are available in Asia from resellers for a few dollars each. I presume these are reclaimed ones rather than new.

It's a shame that although the V5e is available it is impossible to use without proper documentation.
