Full d/s available from a disti near you for the 16C61, and also a flyer for the 16C73 from the same source. Best regards Alex R.

There are several new PICs on the way. The '63 and '73 were listed in some marketing literature given out at the seminar earlier this year. The '61 and '65 are mentioned in various files included with the PICSTART-16C. I asked a Microchip employee about them, and he was very surprised to find out that the PICSTART referred to these parts; he said they weren't supposed to be talking about them yet. PIC16C61: a 16C71 without the A/D converter (lower cost) PIC16C63: a 16C64 in a 28-pin package PIC16C65: a 16C74 without the A/D converter (lower cost) PIC16C73: a 16C74 in a 28-pin package Some of the marketing literature from the seminar also described a 17C44, which is a 17C42 with more memory. Last year I didn't think the 17C4x was very cost effective, since the prices were comparable to the 68HC11, although admittedly the 17C42 runs faster. Since Motorola is unable to keep up with demand and 68HC11 prices have gone up considerably, the 17C42 is looking very attractive. The Mitsubishi 377xx family also is good for high performance low power embedded applications, but I can't actually recommend Mitsubishi because they are very hard to deal with and tend to screw small companies royally.

I'll second Eric's comments on Mitsubishi (being hard to deal with). When I was considering design ideas for a widget we eventually built 11,000 of, I called Mitsubishi to ask about a 'perfect for the task' 4-bit CPU that they had. I had a terrible time getting through, only to find that they wouldn't even *talk* to me unless I could promise an initial production run of 100,000+ pieces. Paid up front. (!) Microchip sent me free samples and an apps engineer. Easy, huh? .....forbesmKILLspam.....csos.orst.edu Mark G. Forbes
