it is a microcontoller ( a version of 8051) At denotes ATMEL company C stands for CMOS 9 stands for flash memory
the 8051 microcontrroller is the name doesnt matter easy or not....but the maiin and imp diff between both is at89s51 represents the 8051 chip no....along with the name of company i.e atmel, so all n all both are same thing ...... 89c51 have RISC architecture and contains less no of opcodes which are easy for programming. so iti is preferred than 8051.
can we replace AT89c51 by AT89s52 but i have c51 code
CMOS
89c51 microcontroller is of the series of 8051,one of oldest yet commonly used microcontroller.89c51 have the less complex features then other microcontroller and it is also easily available and cheap in comparison of other microcontrollers.

AT89C51 function
The 8051 is a microcontroller. It has the MCS-51 core by Intel and was designed for embedded systems in the 1980's. The name of the CMOS version is 80C51. Today the core is still used in microcontrollers from other companies like Atmel, e.g. AT89C51.

I'm more of a PIC guy, but as far as i understood it, yes 8051 instruction set is the same for all 8051 legacy devices. That includes 89s52. You can find this out in device specific datasheet. For 89s52 it is written in a first row like this "Compatible with MCS®-51 Products".

because i said so thats why
