We use the 16C63A a lot, does anyone have a simple answer to what the next chip after this one would be? I would like to get the exact same footprint and operation specs only in a flash part. I am curious why Microchip doesn't give a migration path list on their website, they have so many models, a tree showing compatability or near compatability (at least footprint wise) would be a grea...

Outside of the hobbyist ecosystem, what is the actual market size for new, non-legacy, ICs with a maximum Vcc of ~5V ? I've just picked up a few of the new Microchip 1Mbit SPI RAM ICs: http://uk.farnell.com/microchip/23lcv1024-i-p/sram-serial-1mbit-2-5-5-5v-8pdip/dp/2291921 and I was utterly amazed to see them available in this 5V capable packaging. This is a product range which until...

Hi, I would like to select a Floating Point DSP. I was looking-up the Microchip website and I see things like: "Support for Floating Point" and "Floating Point Library" I get a feeling as if they only have a software workaround and not a true Floating Point hardware implementation. Somehow their wording about Floating Point DSPs does not sound like that of TI or ADI. It ...

I need protocol stacks for Android, including ADB, MSD, BEE, etc. Says Linux? It's too big and no native support for BEE (ZigBee). Says Atmel or Microchip? I've worked with both USB stacks. They are both very similar: inefficient and deficient. I wonder who copy whom. I've been porting and rewriting the microchip USB host stack. I came to the conclusion that it doesn't work with composi...

I have a number of older PIC projects that were written using Parallax assembly mnemonics for the 16C56 and 16C57, and I need to firstly convert the source code to Microchip mnemonics, and then make the programs run on newer PIC's with flash memory instead of OTP.

I'm in the process of choosing between either using Microchip's C18 compiler or the CCS compiler. I've read the comparisons as far as features go and both are comparable although CCS does seem to have somewhat more features. But one of the really big factors is simply how big the developer communities compare. How much sample code is there on the web for both compilers. When I google the k...

Microchip controllers are very cheap, and the tools needed to start developing applications are the cheapest existing today! All you need is the ICD2 Programer/Debuger tool, about 200 USD, and a good tutorial book.

Microchip PIC32 MCUs can be used for graphics applications (as I read on their website), but I couldn't understand if they have a real integrated TFT controller (as in LPC MCUs by NXP) or a different thing.
