89s .. has ISP interface for programming.
89c .. not compatible for ISP interface but needs parallel programming.

What is the difference between AT89s51 and AT89c2051 chips?
Salam,

For AT89S51 It can be programmed in circuit and it has 4KB program flash memory.

AT89C2051 has 2KB flash memory only.

I suggest to use AT89S51.
