Which PIC

[KeithSloan]

I generally leave a PIC16F877A in my programmer as although it is over kill for a number of applications it supports all 5 ports and supports everything else I have ever needed i.e I2C etc. I just plug in the relevant E-Blocks and load the relevant software and go.

Now I want to create a simple application that I plan to build and run separately from the programmer. It only needs one data port ( in fact only one line ). I want to build with the minimum of hardware. I remember coming across applications that use a PIC's with an inbuilt clock, thus avoiding an external crystal or RC network, but cannot remember which PIC it would be.

That is I would like to reduce my project to PIC, Voltage regulator chip, InfraRed diode.

Anybody able to refresh my memory.

Thanks Keith

The Microchip website has a good parametric search function that will allow you to select the appropriate features for your target chip:

Hello

A 8 pin 12F series might be what you are looking for. I think that they all come with the internal oscillator as standard.

On Checking PPP, of the 12 family, it only seems to support 12F629 and 12F675 both of which run at 4Mhz.
Does that mean if I want to use one of the other 12 Family members I am out of luck as far as programming it is concerned.

Hello

You may have to download the latest version of PPP from here.

This version supports the 12F609, 615, 629, 635, 675, 683

I already had version 3.9.12.26 installed.

I forgot that switching to expert mode gave the option of more PIC's than without.
