描述

除了具有低电流消耗(CPU工作时:37.5μA/MHz;STOP时:200nA)外,RL78/G22微控制器还配备了丰富的电容触摸通道。完备的16-48引脚封装和32KB-64KB闪存,扩充了新一代RL78通用微控制器的产品线。

除了最大工作频率32MHz、广泛的工作电压范围(1.6V-5.5V) 和增强的模拟和安全功能之外,SNOOZE模式可编程控制器还可大幅降低间歇工作的功耗。此外,还可为RL78/G22提供丰富的开发环境,评估板(Fast Prototyping Board)只需连接USB线而无需额外工具即可编写和调试程序,智能配置器(Smart Configurator)可通过GUI简化设计。它与现有的RL78系列兼容,可无缝切换,适用于从家电、消费类电子产品到工业设备的广泛用途。
