微控制器是单个集成电路 (IC),可与小型独立计算机相媲美,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 微控制器在不同的架构和不同的指令集、速度、转换、内存、功耗、总线宽度等方面彼此不同。 现在让我们详细了解它们究竟是什么以及它们有何不同从彼此。
1. 8051 微控制器:
它是 8 位微控制器系列。它是一款入门级微控制器,用于世界各地的大多数基本应用,功耗低,预算低。它是由 Intel 于 1981 年开发的。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 微控制器:
PIC 代表外设接口控制器。 PIC 微控制器由 Microchip 开发。从实现和性能的角度来看,该微控制器是一种非常快速的简单微控制器。该微控制器易于编程,也易于与其他外围设备连接。
