In 16F876, port A conmtains ADC only where as in 16F876A, port A contains ADC & COMPARATORS. Program memory write is 1 byte on 16F876 and 4 bytes in 16F876A

Cheers

migrating 16f876

Hi Vikas
There is a document which details the differences between these two chips. See:
https://ww1.microchip.com/downloads/en/DeviceDoc/39591a.pdf
From that doc:
Except for items listed in Table 1, PIC16F87XA is designed to be pin-to-pin, and functionally compatible with the
PIC16F87X product family. Table 1 shows the considerations that must be taken into account when migrating from the
PIC16F87X to the PIC16F87XA. Table 2 shows the electrical and timing differences.
Have a look at it, I think you will find it useful.
Regards,
Robert
