Post by thread:windowed PIC clockspeeds

Hi PICers, I bought a PICStart board and it came with two PICs. A 16C55 and a 16C71. Both with windows (/JW versions). The question is: I thought that the info on the IC will state the clockspeed that are made for. but it doesn't. So, Can i run the PICs at the maximum colckspeed? (16Mhz the 16c71 and 20Mhz the 16c55). Anybody knows the power cnsumption of the PICs at those clockspeeds? Thanx in advance Spiros Papageorgiou Email: spam_OUTpapageTakeThisOuTtheseas.ntua.gr .....mc89114KILLspam@spam@central.ntua.gr

Due to the added expense of a cerdip package, the marginal cost increase for using a fast (e.g. 16MHz) versus slow die is not significant; thus, AFAIK, all of the cerdip package PICs are in the fastest speeds available and I would expect that they use the same power/current as the PDIP versions at the same speed.

So, Can i run the PICs at the maximum colckspeed? >(16Mhz the 16c71 and 20Mhz the 16c55). The windowed versions (JW) can be used with any type of clock (RC, xtal, etc.) and thus at any speed (0 to 20MHz for 16c55) Remember to set the programmer for the type of clock used thou. >Anybody knows the power cnsumption of the PICs at those clockspeeds? The power required can be found in the Microchip Data Book that came with the PICStart.
