What is MCS-51 family?
Intel’s original MCS-51 family was developed using N-type metal-oxide-semiconductor (NMOS) technology, like its predecessor Intel MCS-48, but later versions, identified by a letter C in their name (e.g., 80C51) use complementary metal–oxide–semiconductor (CMOS) technology and consume less power than their NMOS …
What is the major difference between 8051 and 8052 microcontroller?
8052 is the super set of 8051 as it has all the features of 8051 with an extra timer and an extra RAM of 128 bytes. Therefore, 8052 has a total of 256 bytes of RAM and 3 timers in all. Also all the programs written for 8051 will run on 8052 as 8052 is super set of 8051, but it’s reverse is not true.
What is the main function of microcontroller?
