APPENDIX A: REVISION HISTORY
APPENDIX B: DEVICE DIFFERENCES
The differences between the devices in this data sheet
are listed in Ta ble B- 1.
APPENDIX C: CONVERSION CONSIDERATIONS
Considerations for converting from previous versions of
devices to the ones listed in this data sheet are listed in
the following:
PIC16C774 vs. PIC16C74A
• RA2 Added VREF- and VRL
• RA3 Added V
REF+ and VRH
• RA5 Removed SS
•Pin 11 AVDD vs. VDD
•Pin 12 AVSS vs. VSS
• RB1 Added SS, SS is now ST vs. TTL
• RB2 Added AN8
• RB3 Added AN9 and LVDIN
PIC16C773 vs. PIC16C73A
• RA2 Added VREF- and VRL
• RA3 Added V
REF+ and VRH
•Pin 7 AV
DD vs. removed RA5/SS/AN4
•Pin 8 AV
SS vs. VSS
• RB1 Added SS, SS is now ST vs. TTL
• RB2 Added AN8
• RB3 Added AN9 and LVDIN
Program Memory Differences
none
Data Memory Differences
1. Data memory size has increased to 256 from
192 by adding bank 2.
2. Bank 1 locations 0xF0 - 0xFF are now common
RAM locations across banks 0-3.
Peripheral Differences
1. 12-bit A/D replaces 8-bit A/D.
2. Master Synchronous Serial Port replace
Synchronous Serial Port.
3. USART adds 9-bit address mode to module.
4. Bandgap Voltage Reference added.
5. Low-voltage Detect Module added.
6. Selectable Brown-out Reset voltages added.
