Renesas RE01 Group系列32位ARM MCU开发方案

Renesas公司的RE01 Group系列是采用创新的SOTB™工艺,具有超低的工作电流和超低的待机电流,低压1.2V时具有高工作频率,最大64MHz.器件集成了32位Arm® Cortex®-M0+ MCU,1.5MB闪存,256KB SRAM,能量收获控制电路,MIP LCD控制器,2D图像引擎,14位超低功耗ADC,基准电压发生电路,RTC,次时钟修正电路,安全功能(可选),USB 2.0全速模块,SPI和quad SP.主要用在可穿戴设备,家用电器,建筑物自动化,工业传感器设备,智能锁,资产跟踪器和其它应用.本文介绍了RE01 Group主要特性,Cortex-M0+ CPU 框图,RE01 Group框图以及评估板RE01 1500KB主要特性和指标与MIP-LCD扩展板指标,主板布局图和MIP-LCD扩展板布局图,以及主板电路图和MIP-LCD扩展板电路图.
The RE01 Group uses Renesas’ innovative SOTB™ process technology and realizes both ultra-low active current and ultra-low standby current, and high-speed operation (maximum 64MHz) at low voltage (1.62V), which is impossible with a conventional bulk transistor, and is an embedded controller that can operate by energy harvesting. It is equipped with an energy harvesting control circuit, ultra-low power consumption 14-bit ADC (approx. 4uA), flash (rewrite at less than 1mA), parallel MIP-LCD interface, 2D graphics, UI for clock movement, and security functions such as a trusted secure IP. It also has large-capacity 1.5MB flash and 256KB SRAM that can handle data logging and firmware updates. Therefore, the RE01 Group is suitable for wearable devices, home appliances, building automation, industrial sensor devices, smart locks, asset trackers, and other applications.
