模拟,通信,时序和控制外设以及闪 存,是低功耗高可靠性和高性价比的 MCU,工作电压 2.7V-5.5V,主要用在消费类 电子如洗衣机,空调系统,冰箱,计算机冷却风扇,以及 DC/DC 转换器,电表,电梯控 制板,工业机器控制和电路断路器等.本文介绍了 Kinetis KE02 系列 MCU 主要特 性,框图, 开发平台 FRDM-KE02Z 主要特性,框图和电路图. The KE02 sub-family is the entry-point to the Kinetis E series and is pin compatible within E series and with the Freescale’s 8 -bit S08P family. This sub-family includes a powerful array of analog, communication and timing and control peripherals with specific flash memory size and the pin count. The family acts as a low-power, high-robustness, and cost-effective microcontroller to provide developers an appropriate entry-level 32-bit solution. The family is next generation MCU solution with enhanced ESD/EMC performance for costsensitive, high-reliability devices applications used in high electrical noise environments.
