freescale公司的Kinetis EA系列MCU是基于ARM的可升级低功耗的32位MCU,接纳高达48MHz ARM Cortex-M0+内核,具有单周期32位X32位的乘法器,工作电压2.7V-5.5V,闪存写电压范围2.7V-5.5V,工作温度-40 到125℃,主要用在汽车电子如HVAC,门窗和座位控制,情况灯控制,TPMS以及马达控制等.本文先容了Kinetis EA系列MCU主要特点,框架图, 以及用于CAN和BLDC/PMSM马达控制的TRK-KEA128开辟平台主要特点,电路图和质料清单.

Kinetis EA series MCUs for automotive provide an automotive-grade, scalable, 32-bit portfolio with a broad ARM ecosystem for a wide range of automotive applications. The EA series is pin compatible with Freescale’s 8-bit S08RN family and include a powerful array of analog, communication and timing and control peripherals with specific Flash memory size and pin counts. This MCU series offers low-power, built on the ARM®-Cortex® M0+ core, high-robustness and cost-efficiency to provide automotive developers with an optimized ARM-based solution. This series was designed with EMC/ESD in mind to ensure strong noise immunity and low radiated emissions.
