德州儀器(TI)宣布推出最低批量單價(jià)不足2 美元的新型32 位TMS320F280xx 微控制器Piccolo F2802x/F2803x ,TI宣稱的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
出現(xiàn)的新特點(diǎn):MCU 具備可編程性、浮點(diǎn)控制律加速器 (CLA) .TI稱僅一個 F28027/F28035 控制器就可精確控制兩部電氣三相馬達(dá),并可執(zhí)行功率因數(shù)校正 (PFC) 計(jì)算.
如果真的能做到低于2$,這絕對是一款性價(jià)比相當(dāng)高的產(chǎn)品,強(qiáng)烈建議廣大同行關(guān)注!
