MPR083EJ Touch sensor
The MPR083 is a capacitive touch sensor controller with an integrated I2C bus designed to manage 8-position rotating capacitive array sensors. The device supports multiple deployment methods with three output mechanisms and offers a wide range of configuration options.
characteristic
- 41μA平均工作电流，1s响应时间
- 2μA待机电流
- 可变低功耗模式响应时间(32ms–4s)
- 拒绝EMI事件引致的多键值检测，如PA突发或用户操作
- EMI事件不重置触控板分析与监测
- 数据按FIFO缓冲最大限度缩短存取时间
- FIFO有数据时的IRQ输出建议
- 在连续中断后的最短事件或程序时间间隔内，系统可立即设置中断行为
- 轮询系统始终保持当前旋转位置
- 扬声器可在触摸旋转时发出键击音
- 两个硬件可选I2C地址允许一条I2C总线配置两个器件
- 工作温度范围-40℃至+85℃
Target application
- 家电
- PC外设
- 接入控制
- MP3播放器
- 远程控制
- 移动电话
