sourceforge.net /projects /mcu8051ide / 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.
An 8051 chip could be sold as a ROM-less 8031, as the 8051's internal ROM is disabled by the normal state of the EA pin in an 8031-based design. A vendor might sell an 8051 as an 8031 for any number of reasons, such as faulty code in the 8051's ROM, or simply an oversupply of 8051s and undersupply of 8031s. Intel P8044AH microcontroller
The Small Device C Compiler (SDCC) is a free-software, partially retargetable [1] C compiler for 8-bit microcontrollers. It is distributed under the GNU General Public License. The package also contains an assembler, linker, simulator and debugger. SDCC is a popular open-source C compiler for microcontrollers compatible with Intel 8051/MCS-51 ...
Turbo51 is a compiler for the programming language Pascal, for the Intel MCS-51 (8051) family of microcontrollers. It features Borland Turbo Pascal 7 syntax, support for inline assembly code, source-level debugging, and optimizations, among others. The compiler is written in Object Pascal and produced with Delphi.
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 ...
Processor design is a subfield of computer science and computer engineering (fabrication) that deals with creating a processor, a key component of computer hardware.. The design process involves choosing an instruction set and a certain execution paradigm (e.g. VLIW or RISC) and results in a microarchitecture, which might be described in e.g. VHDL or Verilog.
Among the first of the AVR line was the AT90S8515, which in a 40-pin DIP package has the same pinout as an 8051 microcontroller, including the external multiplexed address and data bus. The polarity of the RESET line was opposite (8051's having an active-high RESET, while the AVR has an active-low RESET ), but other than that the pinout was ...
