Most modern 8051-compatible microcontrollers include these features. The 8032 had these same features as the 8052 except it lacked internal ROM program memory. The 8751 was an 8051 with 4 KB EPROM instead of 4 KB ROM. They were identical except for the non-volatile memory type.
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 ...
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. It supports two programming languages: C (using SDCC ) and assembly and runs on both Windows and Unix -based operating systems, such as FreeBSD and Linux .

The Atmel Dragon is an inexpensive tool which connects to a PC via USB. The Dragon can program all AVRs via JTAG, HVP, PDI, [37] or ICSP. The Dragon also allows debugging of all AVRs via JTAG, PDI, or debugWire; a previous limitation to devices with 32 KB or less program memory has been removed in AVR Studio 4.18. [38]
In the 1980s, Intel introduced the 8051 as the first member of the MCS-51 processor family. Today, hundreds of cheap derivatives are available from tens of manufacturers. This makes the architecture very interesting for professionals and hobbyists. It is surprising that this 8-bit architecture is still in use today, and is still so popular.
Harvard architecture. The Harvard architecture is a computer architecture with separate storage [1] and signal pathways for instructions and data. It is often contrasted with the von Neumann architecture, where program instructions and data share the same memory and pathways. This architecture is often used in real-time processing or low-power ...
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.
