AT-89c51 and AT-89c52 compatible issue?

[dashkil]

i have done a silly mistake. i have chosen AT-89c51 as device for my project while writing a code in keil c, later i found that, device i bought is AT-89c52 and i load that program in AT-89c52( while loading i have chosen AT-89c52 as a device in loader software).

Now the question is: will my program work on AT-89c52?

all 89c51's function can be applied on 89c52, it will work correctly. but not all 89c52's function can be applied on 89c51.

RAM 89c51 = 128 bytes, 89c52 = 256 bytes
EEPROM 89c51 = 4Kbytes, 89c52 = 8Kbytes
Timer 89c51 = 2, 89c52 = 3
