Microchip has a much higher price to sale ratio vs. Atmel. They can lower their P/S with this deal, even if they pay a premium. Atmel is a dog with their money losing fabs and many businesses.

It will probably be in the RF/ASIC group, to be sold to a third company. Microchip and On-Semi do not want the RF/ASIC stuffs. Atmel should have spinned off these earlier and concentrates on the AVR. One thing I would like Microchip to do is to bring on ROM AVRs. ROM PICs are available for many years. Atmel does not understand the uC business.

Seems a strange move for Microchip. Maybe they are simply cashed up, and see a fire-sale price in an industry they know ? On-Semi did just buy AMIS, but Microchip have always been more of a loner. Is the MIPS32 not getting the traction they hoped, so they need a side-door to ARM, Cortex, or even AVR32 ? Automotive AVR's ? The ATxmega is an interesting family, tho not yet in small packages. No mention is made of Atmel's CPLDs ? ( or of Atmel's R&D efforts...) - The omission of Atmel Roadmaps, suggests this is a cynical harvesting effort ? -jg

I thought you were being facetious until I read that link. That's very interesting. There seemed to be such a rivalry between the adherents the respective architectures, I wonder how they are all going to take it. I guess it is bank switching forever then for me. :) -pete

Microchip proposes an acquisition, and Atmel ceases to exist regardless of whether there's a deal or not? -- Grant Edwards grante Yow! Is this going to at involve RAW human ecstasy? visi.com

What Atmel? There is no more such company.

If you can evaluate a CPU by its instruction set: http://documentation.renesas.com/eng/products/mpumcu/rej09b0001_r8csm.pdf donald

Looks like its their own design: Page 15 of: http://documentation.renesas.com/eng/products/mpumcu/rej03b0144_r8c1a1bds.pdf donald

What is their CPU core based on, or similar to? Thanks.

Don't forget to look at the Renesas R8C series chips. They have all the features you are interested in, and best free development tools out there. The HEW IDE can be downloaded from the website, and offers GNU (unlimited) or Renesas Compiler (free up to 64k). Debug is done via a one wire connection. They are code compatible with the Renesas M16C chips that have large 1MB memory maps. http://www.renesas.com/en/r8ctiny
