8051 technical data features and Core Specification
the 8051 is popular 8 bit microcontrollers and has an instruction set that enable coding of tiny,I/O intensive, application . with large Program Memory that it is possibly to be used with C. it is manufacturers by Intel . greatly used in embedded systems. now manufactured by may independent manufacturers . the designation for this family is MCS 51. the microcontrollers was build using NMOS . however the version recognize by a C (80C51) use CMOS , This enable it to be more appropriate for battery operated devices. instruction time: It has an instruction time of 1 µ s ( at 12 MHz) newer one may perform 40 instructions per 1 µ s at 40 MHz.
