What is the difference between 8051 and at89c51 microcontroller?

The basic difference between these two controllers is in their RAM memory and flash memory. 8051 is a genric name. 89c51 as 4K flash and 89c52 as 8K flash.

What is the major difference between the 8051 and 8052 microcontrollers?

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 8051 series microcontroller?

8051 microcontroller is designed by Intel in 1981. It is an 8-bit microcontroller. It is built with 40 pins DIP (dual inline package), 4kb of ROM storage and 128 bytes of RAM storage, 2 16-bit timers. It consists of are four parallel 8-bit ports, which are programmable as well as addressable as per the requirement.

What is 8051 microcontroller board?

8051 Development Board with inbuilt programmer. On board Voltage Regulator with filters and operating voltage- 5V to 12V. DB-9 connector to connect with the serial port of the computer(UART communication). On Board IN-circuit programmer consisting AT89C2051 and MAX232. 11.0592 MHz Crystal Oscillator for clock pulsing.

What is the difference between AT89s52 and AT89c52?

Hi, AT89s52 is “In-System” programable, u can program simply with your PC, whereas AT89c52 is programmed with the programmer.

What is difference between at89s51 and AT89C51?

The only difference between the the 89c51 and 89s51 is that the 89s51 and all S series chips can be programmed through both the ISP port and parallel port. But the 89c51 can be programmed only through parallel programmer.

Why microcontroller is 8051?

In 1981, Intel introduced an 8-bit microcontroller called the 8051. It was referred as system on a chip because it had 128 bytes of RAM, 4K byte of on-chip ROM, two timers, one serial port, and 4 ports (8-bit wide), all on a single chip. This has led to several versions with different speeds and amounts of on-chip RAM.
