Hi Ulf,> The AT91SAM7S series will be available in > 32kF+8kR,64kF+16kR, 128kF+�32kR, 256kF+64kR etc.Just so you know, we are looking very hard at these parts in our migration away from horrible legacy 8-bit micros. I'm trying to get managerial permission to port one or two simple projects to ARM in order to pave the way for other projects.> Philips LPC has similar combinations, although the flash size seems to beWe hate Philips :)> With low cost ARM toolsets around the corner it is maybe time to to move onIs there something new coming out soon? If you want to forward me any info, you know my email address...

After my post I remembered an e-mail I recently received from our local distributor: 3.16 euro for the AT91SAM7S32 and 4.57 euro for the AT91SAM7S64, both in 100 units. So that's a good and cheap solution.> If you can fit the latch in your design, why complain?Well, I can fit it in, but the routing requires as much extra board space as required by the latch and SRAM. And it leaves me no room for expansion of the design. But these new ARM mcu's are just the solution I was looking for. The moment they're available here in the Netherlands, I'll design them in. Regards, Meindert
