Post by thread:[PIC]:desired feature

I need a microcontroller with the following features: 1) 32 IO 2) 64K code 512+ flash 2K+ eeprom 3) 2 counter (e.g. TIMER0 / TIMER1) 4) 2 external counter (e.g. INT0 INT1) 5) serial interface (such as using TIMER2) 6) C compiler Can I have a PIC with these features ? which 8051 based microcontroller can I use ?

You might want to look at the Atmel AVRs. The mega64 and mega128 have 64K and 128K of FLASH code space respectively, 53 IO, 4K RAM, 2-4K EEPROM, 2 serial ports, 2 8-bit and 2 16-bit counters, a bunch of interrupts, and a free C compiler (GCC). ISP programmer is about $30 I think. Unfortunately these specific parts are not available as DIPs, although some of the smaller ones are. Go to http://www.atmel.com/atmel/products/prod199.htm for a complete list. Atmel also makes 8051s - the AT89s.

The line card is a good place to answer questions like this. However, if you are in the early phases of a design, the specs are probably not as rigid as you state them above. It's rare that you find a microcontroller that has exactly what you want, at least not for a reasonable price. The best thing is to start out with a rough but flexible idea what you want, then see what's actually available, then rethink the design. You can often use features that you didn't think of in clever ways to get the job done, even though the micro doesn't have some features you originally thought were necessary. This is why it's so important to be familiar with the range of offerings in a few broad families of micros, like the PICs. To specifically answer your question, check out the PIC 18F452. It has much of what you are asking for plus a few additional features. I don't know your application but there is a reasonable chance that this chip can do the job, although perhaps not exactly the way you envision it right now. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: To leave the PICList .....piclist-unsubscribe-requestKILLspam.....mitvma.mit.edu>
