The 12F509
The 12F509 is another device that is designed for cost reduction. It is similar to the 16F84 (but has less RAM and no EEPROM)
If you know that you will never have to use specific peripherals (e.g. the
ones on the 16F88 or 16F877 etc.) then you can put this into your design to
save costs.
The advantage of this device is that it is In-Circuit-Programmable via the ICSP
and it also has one peripheral so it is a useful device for simple timing
applications and it has a bit more memory than the 12F508.
Note: If you use a compiler you're going to
have to be very careful about RAM usage as it is extremelylow.
