Intel's first MCS-51 microcontroller was the 8051, with 4 KB ROM and 128 byte RAM. Variants starting with 87 have a user-programmable EPROM, sometimes UV-erasable. Variants with a C as the third character are some kind of CMOS. 8031 and 8032 are ROM-less versions, with 128 and 256 bytes of RAM. The last digit can indicate memory size, e.g. 8052 ...
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.
Microcontroller products are centred around an ARM core in the case of 32-bit products and 8051 based core and Holtek's own core in the case of 8-bit products. Located in the Hsinchu Science Park ( [1] ), the company's product range includes the following microcontroller device series:
Zilog Announces Z8051 MCU Development Tools Featuring a Wide Array of Industry-Standard 8051-Based Solutions MILPITAS, Calif. & BIEL, Switzerland--(BUSINESS WIRE)-- Zilog, a wholly-owned ...
The die from an Intel 8742, an 8-bit microcontroller that includes a CPU running at 12 MHz, 128 bytes of RAM, 2048 bytes of EPROM, and I/O in the same chip Two ATmega microcontrollers. A microcontroller (MC, UC, or μC) or microcontroller unit (MCU) is a small computer on a single integrated circuit.
The first Atmel flash memory microcontroller was based on the Intel 8051. [7] The controller executed an instruction for every clock cycle, as opposed to the 12 cycles that legacy 8051 parts required. [8] In 1994, Atmel purchased the EEPROM assets of Seeq Technology (LSI Corporation acquired the rest of Seeq in 1999).
SDCC is a popular open-source C compiler for microcontrollers compatible with Intel 8051/MCS-51. [2] [3] [4] Supported hosts.
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 ...
