The Intel 8051 is a Harvard architecture, single chip microcontroller which was developed by Intel in 1980 for use in embedded systems. The official designation for the 8051 family is MCS 51. Intel’s original versions were popular in the 1980s and early 1990s, but has today largely been superseded by a vast range of faster and/or functionally enhanced 8051-compatible devices manufactured by more than 20 independent manufacturers including Atmel, Infineon Technologies (formerly Siemens AG), Maxim Integrated Products (via its Dallas Semiconductor subsidiary), NXP (formerly Philips Semiconductor), Nuvoton (formerly Winbond), ST Microelectronics, Silicon Laboratories (formerly Cygnal), Texas Instruments and Cypress Semiconductor.
8051 based microcontrollers typically include one or two UARTs, two or three timers, 128 or 256 bytes of internal data RAM (16 bytes of which are bit-addressable), up to 128 bytes of I/O, 512 bytes to 64 kB of internal program memory, and sometimes a quantity of extended data RAM (ERAM) located in the external data space.
With the widely used of 8051 microcontrollers, the 8051 MCU decryption technology has made significant development. We can extract code from MCU for our customers(only for lawful research purposes), part of the MCUs which we can do MCU Crack is as follows:
