| PIC16F88 Overview and Data |
| If we compare the PIC16F88 to the PIC16F84 we find that the PIC16F88 is better in every respect. The PIC16F88 can be used in every circuit where the PIC16F84 is used but software written for the PIC16F84 will need some slight changes to be able to run in the PIC16F88. |

| The PIC16F627A is also a good replacement for the PIC16F84 but as it does not have an analogue to digital converter and it cannot be used with large 14 bit lookup tables the PIC16F627A is considerably less useful than the PIC16F88. |
Two 18 pin 18F PICs have been included to complete the picture. The PIC16F88 is better value and easier to understand.
