What is an 8052 Microcontroller?
Submitted By: Craig Steiner FAQ Last Modified: 09/29/06
- An 8052 microcontroller, generally speaking, is any microcontroller that has an instruction set compatible with the MCS-51 standard. Intel made the original 8052 microcontroller back in 1980. Since then, dozens of semiconductor firms have chosen the MCS-51 standard for their lines of microcontrollers. When we speak of "8052" we are not just speaking of the Intel 8052, but also any other microcontroller that is compatible with the 8052 (it's faster then writing 8052-compatible every time we make reference to it).
What is the difference between 8051 and 8052?

- 8051 was the original microcontroller by Intel (based on the older, but slightly different 8048-family (MCS48)). 8052 is an enhanced version of 8051, adding extra 128 bytes of internal RAM (only indirectly addressable) to 128 bytes present already in 8051 (both directly and indirectly addressable), adding a third timer (Timer2, which has also 16-bit reload mode and various other features), and in version with ROM/EPROM, twice as much ROM/EPROM (8kB) as was in 8051 (4kB).
However, today, both "8051" and "8052" are often used interchangably as a generic name for the whole family.
