The first microprocessor 4004 was invented by Intel Corporation. 8085 and 8086 microprocessors were also invented by Intel. In 1981, Intel introduced an 8-bit microcontroller called the 8051. It was referred as system on a chip because it had 128 bytes of RAM, 4K byte of on-chip ROM, two timers, one serial port, and 4 ports (8-bit wide), all on a single chip. When it became widely popular, Intel allowed other manufacturers to make and market different flavors of 8051 with its code compatible with 8051. It means that if you write your program for one flavor of 8051, it will run on other flavors too, regardless of the manufacturer. This has led to several versions with different speeds and amounts of on-chip RAM.
In support of individuals, colleges and universities worldwide, Silicon Labs has established the 8-Bit MCUniversity Program as a complete embedded programming course on mixed-signal MCUs based on the popular 8051 core. The materials include lectures, development tools, tutorial questions, lab exercises and associated solutions.
The course is based on the second edition of the Embedded Programming with Field-Programmable Mixed-Signal µControllers book that covers in detail the features of the C8051F020 mixed-signal MCU, enabling students to go through basic functions and complex analog features. Both a soft cover and pdf download versions are available below.
In the previous 8051 tutorial, we have seen the basics of 8051 Microcontroller like its history, features, packaging and few applications. In this tutorial, we will continue further by looking at the 8051 Microcontroller Pin Diagram and 8051 Microcontroller Pin Description along with some other details like the basic circuit of the 8051 Microcontroller.
We will first see the 8051 Microcontroller Pin Diagram and Pin Description as it will be easier to understand the architecture later (in the next tutorial). Pin Diagram or Pin out of a device will specify the pins of an electrical connector along with its functions.
This basic circuit of 8051 microcontroller is the minimal interface required for it to work. The basic circuit includes a Reset Circuit, the oscillator circuit and power supply. Let us discuss a little bit deeper about this basic circuit of 8051 Microcontroller.
In this tutorial, we have seen about the 8051 Microcontroller Pin Diagram, Pin Description and the Basic Circuit of 8051 Microcontroller. In the next tutorial, we will continue with the architecture and few other features of 8051 Microcontroller.
Thank U very much for this tutorial I would love to invest in this microcontroller coz they are extremely cheap, also I see them in most chinese products please make more tutorials with examples to interface lcds and others thank u
8051 Microcontroller is a programmable device which is used for controlling purpose.Basically 8051 controller is Mask programmable means it will programmed at the time of manufacturing and will not programmed again, there is a derivative of 8051 microcontroller, 89c51 micro controller which is re-programmable.
All aspects and different parts of the 8051 circuit including data input and output ports (I / O ports), timer, counter, interrupt and UART are covered in this course. During the training process, you will synchronize two fully applied projects with the instructor of the programming course. In the first project, you will build a speed control system for the automatic management of direct current motors that uses the PWM wave as a control element. In the second project, you will build a remote control system that can connect to smartphones and execute user commands. Each of these projects has valuable challenges and exercises that can help you understand the performance of microcontrollers and their different programming methods.
The Intel MCS-51 (commonly termed 8051) is a single chip microcontroller (MCU) series developed by Intel in 1980 for use in embedded systems. The architect of the Intel MCS-51 instruction set was John H. Wharton.[1][2] Intel's original versions were popular in the 1980s and early 1990s, and enhanced binary compatible derivatives remain popular today. It is an example of a complex instruction set computer (but also possessing some of the features of RISC architectures, such as a large register set and register windows) and has separate memory spaces for program instructions and data.
MCS-51 based microcontrollers typically include one or two UARTs, two or three timers, 128 or 256 bytes of internal data RAM (16 bytes of which are bit-addressable), up to 128 bytes of I/O, 512 bytes to 64 KB of internal program memory, and sometimes a quantity of extended data RAM (ERAM) located in the external data space. External RAM and ROM share the data and address buses. The original 8051 core ran at 12 clock cycles per machine cycle, with most instructions executing in one or two machine cycles. With a 12 MHz clock frequency, the 8051 could thus execute 1 million one-cycle instructions per second or 500,000 two-cycle instructions per second. Enhanced 8051 cores are now commonly used which run at six, four, two, or even one clock per machine cycle (denoted \"1T\"), and have clock frequencies of up to 100 MHz, and are thus capable of an even greater number of instructions per second. All Silicon Labs, some Dallas (now part of Maxim Integrated) and a few Atmel (now part of Microchip) devices have single cycle cores.[7][8][9]
To permit the use of this feature, some 8051-compatible microcontrollers with internal RAM larger than 256 bytes, or an inability to access external RAM[20] access internal RAM as if it were external, and have a special function register (e.g. PDATA) that permits them to set the upper address of the 256-byte page. This emulates the MCS8051 mode that can page the upper byte of a RAM address by setting the general-purpose I/O pins.
The 8052 was an enhanced version of the original 8051 that featured 256 bytes of internal RAM instead of 128 bytes, 8 KB of ROM instead of 4 KB, and a third 16-bit timer. Most modern 8051-compatible microcontrollers include these features.
The 80251 8/16/32-bit microcontroller with 16 MB (24-bit) address-space and 6 times faster instruction cycle was introduced by Intel in 1996.[3][45] It can perform as an 8-bit 8051, has 24-bit linear addressing, an 8-bit ALU, 8-bit instructions, 16-bit instructions, a limited set of 32-bit instructions, 16 8-bit registers, 16 16-bit registers (8 16-bit registers which do not share space with any 8-bit registers, and 8 16-bit registers which contain 2 8-bit registers per 16-bit register), and 10 32-bit registers (2 dedicated 32-bit registers, and 8 32-bit registers which contain 2 16-bit registers per 32-bit register).[46]
