来源:21ic 曾以通用DSP闻名于世的TI公司, 已有25年的DSP开发经验,其中让人津津乐道的DSP产品C2000系列最早是为工业应用而开发的。目前C2000产品线已作为MCU产品而存在,为实时控制量身打造,分成Delfino和Piccolo两个系列。近日,德州仪器(TI)携15款最新的 Piccolo 浮点 MCU重磅出击,为低能耗电机控制与可再生能源应用带来的阵阵福音。

15款TMS320F2806x Piccolo浮点MCU,可提供能平衡低成本 Piccolo 与高性能 DelfinoTm 浮点微控制器 (MCU) 的性能,具备优异的数学引擎,包括 80 MHz 浮点 C28xTm 内核、最新维特比复杂数学单元 (VCU) 以及控制律加速器 (CLA) 选项。浮点内核可大幅简化编程,改进与元语言工具的兼容性,与定点解决方案相比性能提升达 40%;最新 VCU 复杂数学单元提供 75 条定制数学指令,可加速处理 PLC 等应用的通信算法,实现提升达 7 倍的因数。

外设包括USB2.0全速(主机和设备)、CAN以及直接存储器存取(DMA);15款MCU的存储器容量范围在52至100KB RAM与128至256KB闪存;控制导向型外设包括150ps分辨率的PWM、3MSPS12位ADC以及具有3个10位参考的模拟比较器。
