8051 vs ARM

8051 vs ARM

A microcontroller is an integrated circuit (IC), which is the equivalent of a stand-alone computer designed to perform specific tasks in an embedded system. For 8051 vs ARM, both the 8051 core and the ARM core are members of the microcontroller. The 8051 microcontroller and the ARM microcontroller have different architectures and different instruction sets, speeds, type conversions, memory, power consumption, bus width, etc. In this article, we’ll take a closer look at what they are, and how they differ from each other.

1. 8051 microcontroller

The 8051 microcontroller is one of the members of the 8-bit microcontroller. It is an entry-level microcontroller suitable for most basic applications with low power consumption and low budget. The 8051 microcontroller was developed by Intel in 1981 and has multiple functions such as serial communication, timer, and interrupt. This microcontroller is used in a variety of devices, with major areas including automotive, medical equipment, and energy management. 8051 microcontrollers may seem a bit dated these days, but they are still widely used.


2. ARM microcontroller

ARM microcontroller is a microcontroller composed of ARM processor core. Based on the CPU family on the reduced instruction set computer (RISC) and ARM microprocessor, RAM, ROM and other peripherals are integrated into a single chip to obtain an ARM microcontroller . It is based on the RISC instruction set architecture (ISA), also known as an advanced RISC machine. There is a large market for ARM microcontrollers and most industries use it for embedded systems as it offers much more functionality than other cores.

3. The difference between 8051 microcontroller and ARM microcontroller

Features of 8051 microcontroller:

(1) There are 8 bits for the standard core bus width in the 8051 microcontroller.

(2) Its speed is 12 clock cycles per machine cycle.

(3) Use UART, USART, I2C, SPI, communication protocols.

(4) Flash, ROM, and SRAM memories are used for 8051 microcontrollers.

(5) It is based on the CISC instruction set architecture.

(6) 8051 microcontroller is based on Harvard’s architecture, but it allows us to connect external memory and simulate von Neumann’s architecture.

(7) The power consumption of the 8051 microcontroller is average.

(8) Its members include 8051 variants.

(9) The cost of 8051 microcontroller is very low compared to the functions provided.

Features of ARM microcontroller:

(1) Most 32-bit bus widths exist in ARM microcontrollers, 64-bit is also available.

(2) Its speed is 1 clock cycle per machine cycle.

(3) Use UART, USART, Ethernet, I2S, DSP, SPI, CAN, LIN, I2C communication protocols.

(4) Flash, EEPROM, and SDRAM memories are used for ARM microcontrollers.

(5) It is based on the RISC instruction set architecture.

(6) The PIC microcontroller is based on the Harvard architecture.

(7) The ARM microcontroller has low power consumption.

(8) Its series include ARMv4, 5, 6, 7 and cortex series.

(9) The cost of ARM microcontrollers is low compared to the functions provided.

The microcontrollers are widely used and cover almost every corner of people’s daily production and life., such as household appliances (rice cookers, refrigerators, fans, washing machines, air conditioners, LCD TVs and other commonly used household appliances, as well as various audio equipment, niche scales, atomizers, etc. ); medical equipment (thermometers, electronic thermometers, various analyzers, ventilators, monitors and ultrasonic diagnostic equipment, etc.); industrial control (intelligent management of factory assembly lines, intelligent control of building elevators and various alarms systems, etc.); the field of intelligent instruments and meters (watt-hour meters, oscilloscopes, various analytical instruments); the field of computer network communications (such as mobile phones, remote monitoring switches, automatic communication calling systems, wireless walkie-talkies, etc).

But a microcontroller is a chip that can be programmed, which is equivalent to a single-chip computer, it needs to add some peripheral circuits to realize common functions.

The microcontroller can be inserted into the development board, the microcontroller code written on the computer can be downloaded to the microcontroller, and the program written by the user can be used to control the hardware work on the development board to realize more product functions.
