intel 8051 การใช้

• The original Intel 8051 ran at 12 clock cycles per machine cycle, and most instructions executed in one or two machine cycles.
• Based on the Intel 8051 core, the AT89 series remains very popular as general purpose microcontrollers, due to their industry standard instruction set, and low unit cost.
• The " 8031 " was a cut down version of the original Intel 8051 that had no internal program memory ( read-only memory ( ROM ) ).
• The ECU uses an Intel 8051 microcontroller, usually with 16 kiB of program memory and without advanced on-board diagnostics ( OBD-II ) became a requirement in model-year 1996 .)
• Wharton, the designer of one of Silicon Valley's most popular computer chips, the Intel 8051 microcontroller, flew to Fiji twice in the past two weeks to comb the beaches for debris from the Mir space station.
• The Intel 8051, contrary to other Intel processors, expects 16-bit addresses for LJMP and LCALL in big-endian format; however, xCALL instructions store the return address onto the stack in little-endian format.
• Its products include microcontrollers ( 8-bit ARM-based, automotive grade, and 8-bit Intel 8051 derivatives ) radio frequency ( RF ) devices including Wi-Fi, EEPROM, and flash memory devices, symmetric and asymmetric security chips, touch sensors and controllers, and application-specific products.
• Well known microprocessors and microcontrollers that have also been labeled CISC in many academic publications include the Motorola 6800, 6809 and 68000-families; the Intel 8080, iAPX432 and x86-family; the Zilog Z80, Z8 and Z8000-families; the National Semiconductor 32016 and NS320xx-line; the MOS Technology 6502-family; the Intel 8051-family; and others.
