第1章芯片结构及性能概述TMS320C2000系列是美国TI公司推出的最佳测控应用的定点DSP芯片，其主流产品分为四个系列：C20x、C24x、C27x和C28x。

C20x可用于通信设备、数字相机、嵌入式家电设备等；C24x主要用于数字马达控制、电机控制、工业自动化、电力转换系统等。

近年来，TI公司又推出了具有更高性能的改进型C27x和C28x系列芯片，进一步增强了芯片的接口能力和嵌入功能，从而拓宽了数字信号处理器的应用领域。

TMS320C28x系列是TI公司最新推出的DSP芯片，是目前国际市场上最先进、功能最强大的32位定点DSP芯片。

它既具有数字信号处理能力，又具有强大的事件管理能力和嵌入式控制功能，特别适用于有大批量数据处理的测控场合，如工业自动化控制、电力电子技术应用、智能化仪器仪表及电机、马达伺服控制系统等。

本章将介绍TMS320C28x 系列芯片的结构、性能及特点，并给出该系列芯片的引脚分布及引脚功能。

1.1 TMS320C28x系列芯片的结构及性能C28x系列的主要片种为TMS320F2810和TMS320F2812。

两种芯片的差别是：F2812内含128K×16位的片内Flash存储器，有外部存储器接口，而F2810仅有64K×16位的片内Flash存储器，且无外部存储器接口。

其硬件特征如表1-1所示。
