suggestion for a 6-pin PIC

[wejos]

good evening guys,

need your suggestion what 8-pin pic is good to use. cheaper kind the better and programmer should be simple also to make for a novice like me.

thanks in advance,

wejos

Assuming you mean 8 pin (and not 6), the 12F675 is a good coice, and even has analogue inputs.

thanks nigel. i'm always greatful.

yes i meant 8 pin.

i am reading now about the suggested pic.

 

[wejos]

and wow there is really 6 pin i read from "Newcomers, please read!".

Yes, 10F series - but (if I recall correctly) SM only - the DIP version for development is 8 pin.

I like the 12F683. It has double the program size, RAM, and internal oscillator speed of the 675, and can do PWM. I got 5 of them for $10 from here: **broken link removed**

PIC12F683 would be a good start. Check this out: Make Your Own PIC12F683 Development Board

Yeah the 8-pin stuff you can't run ICD on. There's a "header board" using another chip which has more pins which get used for ICD, while only exposing 8 pins for the target board. ICD is really excellent- once I got a programmer which used it, it's hard to go back.

Also a problem which is more likely to come up with low pincount devices- you may need to use the MCLR, PGD/PGC pins as I/O too. In some cases, this is no problem. In other cases, the direction and signals used for ICP are not compatible with the surrounding circuitry, meaning no ICP- it must be programmed off the board and installed. This is a major PITA for development even for DIP, and a huge problem for SMD.

You are correct Nigel.

In addition, according to Microchip, as the die is aimed at a SOT23 package the pinout of the 10F 8-DIP is different to traditional 8-pin packages.

The AC163020 Programmer Adapter Board does the magic for you, but whipping up a 10F_to_8-pin converter on stripboard doesn't take long.
