The Intel MCS-51 (commonly termed 8051) is a single-chip microcontroller (MCU) series developed by Intel in 1980 for use in embedded systems. The architect of the Intel MCS-51 instruction set was John H. Wharton .
A microcontroller can be considered a self-contained system with a processor, memory and peripherals and can be used as an embedded system. [27] The majority of microcontrollers in use today are embedded in other machinery, such as automobiles, telephones, appliances, and peripherals for computer systems.
Manufactures a line of 8-bit 8051-compatible microcontrollers, notable for high speeds (50–100 MIPS) and large memories in relatively small package sizes. A free IDE is available that supports the USB-connected ToolStick line of modular prototyping boards. These microcontrollers were originally developed by Cygnal.
SAB-C515-LN by Infineon is based on the 8051. The Infineon XC800 family is an 8-bit microcontroller family, first introduced in 2005, [1] with a dual cycle optimized 8051 "E-Warp" [2] [3] core. The XC800 family is divided into two categories, the A-Family for Automotive and the I-Family for Industrial and multi-market applications.
An AT89c2051 microcontroller in circuit. The Atmel AT89 series is an Intel 8051-compatible family of 8 bit microcontrollers (μCs) manufactured by the Atmel Corporation.. Based on the Intel 8051 core, the AT89 series remains very popular as general purpose microcontrollers, due to their industry standard instruction set, their low unit cost, and the availability of these chips in DIL (DIP ...
External wiring can also convert a strictly Harvard CPU core into a modified Harvard one, for example by simply combining `PSEN#` (program space read) and `RD#` (external data space read) signals externally through an AND gate on an Intel 8051 family microcontroller, the microcontroller are said to be "von Neumann connected," as the external ...
MCU 8051 IDE is a free software integrated development environment for microcontrollers based on the 8051.MCU 8051 IDE has a built-in simulator not only for the MCU itself, but also LCD displays and simple LED outputs as well as button inputs.
Embedded software is computer software, written to control machines or devices that are not typically thought of as computers, commonly known as embedded systems. It is typically specialized for the particular hardware that it runs on and has time and memory constraints. [1] This term is sometimes used interchangeably with firmware. [2]
