8051和PIC之间的区别

微控制器是单个集成电路(IC)，可与小型独立计算机相媲美，它旨在执行嵌入式系统的特定任务。 8051和PIC属于微控制器家族。 8051微控制器和PIC微控制器在不同的体系结构和不同的指令集，速度，转换，内存，功耗，总线宽度等方面有所不同。现在让我们详细了解它们的实际含义以及它们之间的区别彼此。

1. 8051微控制器：
它是8位微控制器家族。它是一款入门级微控制器，适用于世界各地的大多数基本应用，并且功耗低且预算低。它由英特尔于1981年开发。该微控制器用于各种设备，主要领域包括汽车，医疗设备和能源管理。

2. PIC单片机：
PIC代表外设接口控制器。 PIC单片机是由Microchip开发的。从实现和性能的角度来看，该微控制器是非常快速的简单微控制器。该微控制器易于编程，并且易于与其他外设接口。
