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.

∙ 13y agoInstruction set, Internal memory structure and Pinout are the same. 8951 Controllers which are faster and more complex were first developed in the 90's as an improvement to the 8051.
Many 8951 controllers have 2, 4 or 6 clock cores as opposed to 12. Whats more many provide onboard DAC, ADC, I2C, USB, CAN etc

Who is first invented 8051 microcontroller or 8051 microprocessor?
Intel
Difference between 8031 8051 and 8751 microcontrollers?
Answer It is both 8 bit processors in a 40 pin package but it is not pin compatible, it have almost the same functions but it is very difficult to compare the two because it is not the same family.

What are the Advantages of at89c52 microcontroller over 8051 microcontroller?
The at89c52 are ones that are more advanced. This means that they are programmable compared to the 8051 which is not. So this makes a really big difference.
Difference between avr micro controller and 8051 micro controller?
constructed on a single chip is called micro processor constructed on a single board is called micro controller
What is difference between instructions and assembly directives in 8051?
dirictives is used for variable declaration it cannot execute at run time.. it does nor produce any code....
What is the difference between AT89S52 and AT89C52?
89S52 have 8KB ROM and 256bytes RAM also it supports SPI program downloading but 89C51 have 4Kb ROM, 128bytes RAM and it wont support Serial program downloading. For more details visit www.8051projects.info
