WebAll four ports in the 8051 core are bidirectional. Each port has SFR (Special Function Registers P0 through P3) which works like a latch, an output driver and an input buffer. Both the output driver and the input buffer of Port 0, and the output driver of Ports 2 are used for accessing the external memory.

A History of Early Microcontrollers, Part 8: The Intel 8051
WebDec 19, 2022 · by Steven Leibson. Intel introduced the successor to its 8048 microcontroller, the 8051, in 1980. It’s become the immortal microcontroller, and it was all because an applications engineer forgot to bring his wallet to work one day and asked his boss at Intel to buy lunch. Intel announced the 8048 microcontroller in 1976.
WebThe original Intel 8051 core took 12 cycles to execute 1 instruction; thus, at 12 MHz, it ran at 1million instructions per second (1 MIP). In contrast, a 100 MHz Silicon Labs 8051 core will run at 100 MIPS or 100 times faster than the classic 8051 at a frequency that is only about 8x the classic 8051’s frequency.
