can we replace AT89c51 by AT89s52 but i have c51 code
CMOS
yes both are same
AT89S52 is a microcontroller based on the Intel 8051 architecture and features. Concerning your question, AT89S52 is the heart of most project involving Dual Tone Multi Frequency (DTMF), that is to say it is the controller IC used in such project.
it is a microcontoller ( a version of 8051) At denotes ATMEL company C stands for CMOS 9 stands for flash memory
To limit the amount of current to the ports
AT89C51 function
AT89C51 function

yes
CMOS
semi conductor
32
yes both are same
Its an I\O controller
