描述 Description

TMS320F280015x (F280015x) 是经过成本优化的 C2000 实时微控制器系列的可扩展、超低延迟器件，旨在提高电力电子产品的效率。

这些应用包括：

HVAC 压缩机模块 前灯 直流/直流转换器 逆变器和电机控制 车载充电器 (OBC) 和无线充电器 泵 工业电机驱动 电机控制 数字电源 感应和信号调理 TMS320F280015x 采用 32 位锁步双 C28x CPU，使得该器件无需过多的软件开销即可成为 ASIL B 级功能安全器件。实时控制子系统基于 TI 的 32 位 C28x DSP 内核，可针对从片上闪存或 SRAM 运行的浮点或定点代码提供 120 MHz 的信号处理性能。三角函数加速器 (TMU) 和 VCRC（循环冗余校验）扩展指令集进一步增强了 C28x CPU 的性能，从而加快了实时控制系统关键常用算法的速度。

F280015x 支持高达 256KB (128KW) 的闪存。高达 36KB (18KW) 的片上 SRAM 也可用于补充闪存。

高性能模拟块集成在 F280015x 实时微控制器 (MCU) 上，并与处理单元和 PWM 单元紧密耦合，从而提供出色的实时信号链性能。14 个 PWM 通道可控制从三相逆变器到功率因数校正的各种功率级，以及其他先进的多级电源拓扑。

各种业界通用通信端口（如 PMBUS、SPI、SCI、LIN、I2C、CAN 和 CAN FD）不仅支持连接，还提供了多个引脚复用选项，可实现出色的信号布局。
