2024年3月10日 · The Pin Description or Pin Configuration of the 8051 Microcontroller will describe the functions of each pins of the 8051 Microcontroller. Let us now see the pin description. Pins 1 – 8 (PORT 1): Pins 1 to 8 are the PORT 1 Pins of 8051.

2024年6月12日 · In this introductory series on 8051 Microcontroller, let us understand the Pin Configuration (Pin Diagram and Pin Description) of the 8051 Microcontroller. In the process, we will learn the functions of each and every pin of the 8051 microcontroller.

2024年11月17日 · The pin diagram of 8051 microcontroller gives information about input and output ports, interrupts, serial ports etc. about microcontroller. So, it will be useful to configure it perfectly in any kind of circuit to be build. The 8051 microcontroller has 40 pin to communicate with external machines and interfaces. Each pin has its unique functions.

2016年7月13日 · The document provides an overview of the 8051 microcontroller, including its block diagram, pin descriptions, registers, memory mapping, stack, I/O port programming, timers, and interrupts. It explains the basic components and architecture of the 8051, how it maps memory and handles interrupts and timers.

Explore the detailed pin description of the 8051 microcontroller, including functions, configurations, and applications for effective microcontroller programming.

8051 is an 8-bit microcontroller that contains 40 pins of dual-in-line packaging. Out of the 40 pins, 32 pins are allotted to I/O ports. However, in 8051 there exist multiple pins which are assigned more than one signal.

• The 8051 is a pin 40 pin IC available in Dual-In line package (DIP). • Requires a single power supply of +5V. • Its maximum internal clock frequency rating is 12 MHz.

pin 31 當他是高電位時，如果8051要讀取低位元的記憶體時，會從內部的記憶體讀取；當他是低電位時，則從外部的記憶體讀取。 當然這些都要與 /PSEN配合。

The pin diagram of 8051 microcontroller looks as follows – Pins 1 to 8 − These pins are known as Port 1. This port doesn’t serve any other functions. It is internally pulled up, bi-directional I/O port. Pin 9 − It is a RESET pin, which is used to reset the microcontroller to its initial values.
