hi,

i have worked on pic 16f877 and i m much fimilar to it.

but it is 40pin ic.

can anyone tell me that is there any 20 ic or pic 16f877 coz i just want to reduce my circuit just use two ports uart and three adc sensors....

the controller should have same command register as 16f8777
 

For compatibility's sake, you may take a look at PIC16F873 or the PIC16F883. They have 28 pins by the way.

As for 20 pins, I would recommend PIC16F690. It's feature-packed and very cheap. The registers are not exactly the same, but if you successfully used PIC16F877, you should quite easily be able to use PIC16F690 by consulting the datasheet.

Hope this helps.
Tahmid.
 

Hi.

As per Tahmid, but you will find the 876/A has idential memory and registers to the 877/A, except its in 28 pins
The 873/A only has half the program memory, ram and eeprom.
