In the previous 8051 tutorial, we have seen the basics of 8051 microcontroller like its history, features, packaging and few applications. Specifications of 8051 microcontroller so now let us take a look at the important features of 8051 microcontroller. Microcontrollers 8051 pin description tutorialspoint. A microcontroller consists of a processor, a fixed amount of memory ram, rom, eprom, serial ports and some peripheral devices like. Way more information than you ever wanted on how to fell a tree. Pin diagram of 8051 microcontroller with explanation. Pin diagram of 8051 microcontroller arduino projects, electronics projects, pic. A microcontroller is a small and lowcost microcomputer which is basically designed to perform some specific tasks of an embedded system like receiving remote signals or displaying microwave information etc. On this channel you can get education and knowledge for general issues and topics. Highspeed pipelined 8051compatible microcontroller core up to 25 mips.
Majority of developers uses the 40 pin chip, we will concentrate on that. As we know that cpu is the brain of any device of the microcontroller. It is a reset pin, which is used to reset the microcontroller to its initial values. An onchip crystal oscillator with a frequency of 12 mhz is inserted in the microcontroller. The reasons for the popularity of 8051 microcontroller are simple to integrate in any electronic device. 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. In the following diagram, the system bus connects all the support devices to the cpu. In 8051 pin diagram, you can see that it has 4 ports p0, p1, p2, and p3 and each port has 8 pin. What is the functional block diagram and pin description. Pin diagram of 8051 microcontroller each of these pins can be configured as an input or an output.
Let us now discuss the architecture of 8051 microcontroller. C8051f330 and c8051f331 and c8051f332 and c8051f333 and. The pin diagram of 8051 microcontroller looks as follows 8051 pin diagram. A tutorial about 8051 microcontroller pin diagram, pin description of 8051 microcontroller pins and basic circuit or schematic of 8051.
