****Mikä ero on PIC16F84A ja PIC16F628 välillä? ***************

16F628 compared to PIC16F84  .

- Twice the program memory
- Three times the data memory
- Three timers vs. 1 for the 16F84A
- Two comparators vs. 0 for the 16F84A
- Twice the data eeprom memory
- Hardware USART
- Up to 3 extra I/O pins.
- 4 MHz internal osciallator.
- Runs up to 20 Mhz PIC16F84 is 10MHz and PIC16F84A is 20MHz part.
- Can be low voltage programmed.
- Price for PIC16F628 is coming down and PIC16F84 is going up

The parts are both pin and programming compatible. Be sure to check for any
differences in the Config Word.

Check it out if you get a chance. Also be aware that you will have to make
a few changes to the code. For example the start of general purpose RAM has
moved and the PORTA comparators must be disabled.
