umm 1? lol No, seriously, as explained on www.8052.com, the 8052 has twice the RAM of the 8051 (that is 256 Bytes), an additional 16-bit Timer (Timer 2) and more Special Function Registers (SFR) as required for the additional features. The most essential difference is that Timer2 can be used as a Baud rate generator for serial communication.
