The 12F508 is designed for cost reduction where you know that you will never
have to use specific peripherals (e.g. the ones on the 16F88 or 16F877 etc.)
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
Note: If you use a compiler you're going to have to be very careful about RAM usage as it is extremelylow.
