建议电源同行们关注一下TI单价不足2 美元的新型32 位TMS320F280xx 微控制器Piccolo F2802x/F2803x

德州仪器(TI)宣布推出最低批量单价不足2 美元的新型32 位TMS320F280xx 微控制器Piccolo F2802x/F2803x ，TI宣称的28035的特性如下:
• Enhanced Pulse Width Modulator (ePWM)
• Up to 60-MHz, 32-bit C28x™ CPU
• 32-kB to 128-kB embedded Flash
• 12-bit ADC, up to 4.6 MSPS
• 150-ps high-resolution ePWM
• Control law accelerator
Enhanced Control Peripherals
Up to 15 PWM Outputs
Up to 5 HRPWM(150-ps resolution on both edges for duty and frequency)
1 eCAP Enhanced Capture Input with independent 32-bit timer
1 eQEP Quadrature Encoder Pulse Module with independent 32-bit timer
2 SPI Serial Peripheral Interface with 4-level FIFO
1 SCI Serial Communications Interface (UART) with 4-level FIFO
1 I2C Inter-Integrated Circuit with 4-level FIFO
1 LIN LIN 2.0 controller
1 CAN CAN 2.0B controller
出现的新特点：MCU 具备可编程性、浮点控制律加速器 (CLA) ，TI称仅一个 F2802x/F2803x 控制器就可精确控制两部电气三相马达，并可执行功率因数校正 (PFC) 计算。
如果真的能做到低于2$，这绝对是一款性价比相当高的产品，强烈建议广大同行关注！
