Which other Pics are Compatibly (same pins) with :
pic16f84a - pic16f628a - pic16f648a - pic16f88 - pic16f818 - pic16f819

Go to the Microchip website and fill in the parameters for what you need...

http://www.microchip.com/ParamChartSearch/params.aspx?branchID=1002&mid=10&lang=en&pageId=74

at least then you'll have all the options... folks here won't know every single possible PIC, so the Microchip website is where you should be looking.

Do you mean just the same number of pins.... or the same peripherals connected to pins.

http://melabs.picbasic.com/Scripts/perl/picsearch.pl will allow you to select PICs based on what features you require.

The examples you list above arent what I would deem compatible. The F84A doesnt have a UART. The F88 does have a UART but it is on different pins to the 628A/648A. Cant comment on the other two as I havent looked at them.

I mean the same numbers of pins (18).

PIC1 --> PIC2
-------------------------
pin 1 (RA2) --> pin 1 (RA2)
pin 2 (RA3) --> pin 2 (RA3)
.........................
.........................
.........................
.........................
pin 18 (RA1) --> pin 18 (RA1)

so basically your question is "which pics have 18 pins" because the functionality of those pins can be quite different as can the memory size to shoehorn your program into.

Yes , but one to one.
I have a code for the pic16f84a and if use this code for other pic (16f628 - 16f88) , i change the code (A/D , comparators ,Vref)
