Features of 8051 microcontroller
- It is an 8bit microcontroller.
- 8bit accumulator, 8bit Register and 8bit ALU.
- On chip RAM 128 bites (data memory).
- On chip ROM 4 Kbytes (program memory).
- Two 16bit counter/ timer.
- A 16 bit dptr(data pointer)
- Two levels of interrupt priority.
- 4 byte bi-directional input/ output port.
- Power saving mode (on some derivatives).
- 16bit address bus:-it can access 2^16 memory locations:-64kb (65536) each of RAM and ROM.
- It is an inclusion of Boolean processing system, have an ability to allow logic operations to be carried out on registers and RAM.
- 8bit data bus:-it can access 8bit of data in one operation.
- UART (this serial communication port makes chip to use simply as a serial communication interface).
- It has four separate Register set. (Each contains 8 Registers (R0 to R7)).
- Widely used in industrial control applications
