Post by thread:16K pic and pic17c44

Early next year, Microchip will sample the PIC18 family devices with 32K bytes of OTP program memory and pinouts and peripheral sets compatible with PIC16C77,76.

Also, I am thinking of changing some products to use the pic17c44 - is there any thing special to be aware of when using this device?

Only the crazy price. If are going to change micro anyway, have a look at the 68HC16 family. You get way, way, *way* more bang for your buck. Unless you have MPC, you don't have a proper compiler for the 17C$$$ range anyway, so you might a well go the whole hog. You'll find Motorola quite willing to part with some hardware and software to set you up, too. I think the 17C$$$ prices are calculated with the aim to make people laugh. Instead people buy them. Beats me. I honestly think Microchip are stretching their brand loyalty hair thin with the 17C$$$ prices. Vote with your dollars. -- Friendly Regards /"\ \ / Tjaart van der Walt X ASCII RIBBON CAMPAIGN tjaartspam_OUTwasp.co.za / \ AGAINST HTML MAIL |--------------------------------------------------| | WASP International | |R&D Engineer : GSM peripheral services development| |--------------------------------------------------| |SMS @spam@tjaartKILLspamsms.wasp.co.za (160 chars max)| | http://www.wasp.co.za/~tjaart/index.html | |Voice: +27-(0)11-622-8686 Fax: +27-(0)11-622-8973| | WGS-84 : 26¡10.52'S 28¡06.19'E | |--------------------------------------------------|

In this case I would not recommend the 68HC16, these have been a bit of a flop of Motorola and are neither your knee nor your elbow. Also not all that easy to debug as hardware emulators and such are required. Also the Automotive industry doesn't seem all that interested in these devices (The bulk of the Motorola uP market, hint hint for cost savings, also the 68020 is a good one to look at but requires more work from your part). I would look at the 68HC12, as this has a BDM port, so with simple and cheep tools one can debug on the target. This is also a new range that Motorola will be pushing them aggressively. Dennis

In my experience, the 68* parts used by the auto industry have historically been unavailable for production. But if you use the Hitachi clones...

Yes correct not all parts used in the Auto industry is avaliable to the public as they are NEARLY masked versions, or special versions. But this leads to a basic core that can be used over and over again in others, and thus brings the price down. Remember that the first HC11 was a 6802 with a external timer chip added in for GM (If I can remenber back that far) Dennis

Any idea when data for those things will be coming out? I've been eagerly awaiting ever since our interview last August. Also, just FYI, there is one very good thing that has come from my not moving to Arizona--I've managed to meet a wonderful woman here in the Chicagoland area and got married about a month ago. Feel free to spread the word around to Dick et al if you like. Attachment converted: wonderland:WINMAIL.DAT 14 (????/----) (0001D293)
