not sure if this can help, but EasyPIC 4 development board have 2 different socket for 10F and 12Xxxx. They also sold that board... 12USD

LOL, thanks but no thanks - I've already built it!

Besides I prefer my project anyway as it has a ZIF socket, a built-in power supply and a nice case.

Perhaps I could build an adaptor for odd pinouts like the PIC10F200 as it would be cheaper than buying a new board but I'd rather avoid PICs like that altogether.

Bump.

Alright I'm putting an RS order now so I need to come to a final decision on what PICs to buy.

For the 8 pin DIP:
PIC12F508-I/SN
Order no: 623-0083
Price: 55p

For the 18 pin DIP:
PIC16F54-I/P

Order No: 623-0213
52p
Is this alright? I can't believe it's actually cheaper than the 8 pin DIP!
What's the catch?

All prices exclude VAT which is 17.5% in the UK.

I'll still get a few of the 12F508s anyway as it'll be worth 3p to save me drilling all those holes.

Unless cost is a big issue I would look at PICs with more features.

Look at the PIC12F683

No EEPROM, almost no FLASH or RAM.
No ADC, Comparators, AUSART, I²C, or SPI
No ICD.

Look at the PIC16F88. It has all the above with 4K words of memory and an Internal Oscillator.
You can compare 16F PICs here.

I have not read all through this thread but just wondered why you want to buy a 12f508 - these can only be programmed once. They were popular a few years ago because they were cheap - (often used for chipping playstations).

Sorry- it is the 12C508 i was thinking of that only can be programmed once.


Also the 16f54 is even more obsolete than the 16f84 - why don't you just get a 16f628?

The PIC12F508-I/SN is 0.52 £. It comes in 150 mil SOIC package.
For the DIP8, look at the PIC12F508-I/P that can be programmed without using an adaptor. It's 0.55 £ as you said, but I've seen that it's out of stock?

 

[Hero999]

But I thought it was the PIC12C508A, that can only be programmed once?

The PIC12F508-I/SN is alright, isn't it?

The PIC12C508A is an OTP device, not recommended.
The PIC12F508 looks good for your project, but it's not loaded with peripherals - that might become useful for future projects (ADCs, PWM) - and has a two levels stack. I would buy some PIC12F683s too (my personal favourite).

Also the 16f54 is even more obsolete than the 16f84 - why don't you just get a 16f628?

Because at £1.99, it's over three times as expensive and that's only for the PIC16F628-04/SO, the PIC16F628-04I/SS is £2.36 and I'm not paying that.

Unless cost is a big issue I would look at PICs with more features.

Cost wouldn't be a problem if I only wanted to buy one but I want to get a few so I can practice using them and I don't want to buy expensive PICs in case I ruin them.

I'll go for that, it doesn't bother me that it's out of stock, i've waited long enough so I don't mind waiting a bit longer.
