先决条件–微控制器(µC)和微处理器(µP)之间的差异
微控制器是一个单集成电路(IC)，可与一台小型独立计算机相提并论，它旨在管理嵌入式系统中的特定操作。一个微控制器包含处理单元和少量存储器(ROM，RAM等)，很少有用于外围设备的I / O端口，计时器等。我们可以说这是一个小型且低成本的微型计算机。 PIC和MSP430属于微控制器家族。 PIC微控制器和MSP430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，总线宽度等方面彼此不同。现在，让我们详细了解它们之间的区别。
1. PIC微控制器：
PIC单片机最初被称为外围接口控制器，现在被称为可编程智能计算机。它属于Microchip Technology制造的微控制器家族。它最初是由通用仪器公司的微电子学于1993年开发的。可以对其进行编程以执行各种各样的任务。 PIC微控制器提供8位，16位和32位版本。它基于RISC指令集架构和哈佛内存架构。
2. MSP430微控制器：
它是一个16位超低功耗微控制器，具有德州仪器(TI)的许多功能。它基于Von-Neumann架构，并带有微控制器和Launchpad。它由用于传感和测量应用的模拟和数字设备组成。它是一个RISC微控制器。可以在Code Composer Studio(CSS)IDE，Energia和其他各种IDE中进行编程。该微控制器设计用于低成本和超低功耗的嵌入式应用。
