Experts Outreach for 8051 Microcontroller

Over the years, project development has advanced over leaps and bounds. Of course, it’s good to keep up with the times, but in some situations, radical changes might not be so beneficial. We’re here to talk about the staple microcontroller, the 8051. Many students nowadays are choosing much more advanced microcontrollers because the 8051 is apparently not advanced enough. It’s time to bust that myth, and show how the 8051 microcontroller is still one of the best. In today’s market we can find many more advanced microcontrollers than the 8051 microcontroller like PIC, ARM, and Arduino so on. So what makes 8051 microcontroller stand out among all these controllers? Before we even begin development on advanced platforms, we have to learn root or basic microcontrollers, of which 8051 is one. Anyone who has extensive knowledge on the 8051 microcontroller will be able to grasp advanced concepts easily. We’ve gathered some opinions about 8051 microcontrollers which will perhaps remove some of the misconceptions surrounding the stalwart. We hope that some of these expert reviews change your mind about the 8051 microcontroller.

It contains 4K Bytes ROM, 128 Bytes of on chip data RAM, 32 bidirectional or individually addressable I/O lines, two 16-bit timer/counters, on chip clock oscillator. It is a powerful microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications. Low cost and easy programming process of this microcontroller becomes it widely popular nowadays.

• It can perform as an 8-bit 8051, has 24-bit external address space which is 16-bit wide segmented and 32-bit ALU with mostly 8/16/32-bit wide data instructions (also Boolean processor with special registers/memory) and a large CISC instruction set, 40 8/16/32-bit registers with 8 8-bit registers in 4 times fast switching memory banks (maximum 512 addressable 8-bit special registers).

• It features extended instructions – see also the programmer’s guide and later variants with higher performance, also available as intellectual property (IP).

It is 3-stage pipelined. The MCS-251 family was also discontinued by Intel, but is widely available in binary compatible and partly enhanced variants from many manufacturers.

• Today, 8051s are still available as discrete parts, but they are mostly used as silicon intellectual property cores. It is available in high-level language source code (VHDL or Verilog) or FPGA netlist forms, these cores are typically integrated within embedded systems, this is used in products ranging from USB flash drives to washing machines to complex wireless communication systems on a chip.

• Designers use 8051 silicon IP cores, because of the smaller size, and lower power, compared to 32 bit processors like ARM M series, MIPS and BA22. Modern 8051 cores are faster than earlier packaged versions.

• Design improvements have increased 8051 performance while retaining compatibility with the original MCS 51 instruction set. The original Intel 8051 ran at 12 clock cycles per machine cycle, and most instructions executed in one or two machine cycles.

• A typical maximum clock frequency of 12 MHz meant these old 8051s could execute one million single-cycle instructions, or 500,000 two-cycle instructions, per second.

• In contrast, enhanced 8051 silicon IP cores now run at one clock cycle per machine cycle, and have clock frequencies of up to 450 MHz. That means an 8051-compatible processor can now execute 450 million instructions per second.

Microcontroller 8051 may be called computer on chip since it has basic features of microprocessor with internal ROM, RAM, Parallel and serial ports within single chip. Or we can say microprocessor with memory and ports is called as microcontroller.

The 8051 microcontroller is what everything started from. Whether you need to create advanced projects or simple ones, the 8051 still finds some use. Even though it was introduced way back in 1980, it still finds a lot of application in education and simple products.
