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
Look at the PIC12F683
For the 18 pin DIP:
PIC16F54-I/P
https://docs-europe.electrocomponents.com/webdocs/0806/0900766b80806d04.pdf
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?
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.
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.
