Product Introduction

MPR084Q Touch sensor

The MPR084 is an internal integrated circuit bus (I2C)-driven capacitive touch sensor controller designed to manage 8-button touchpad capacitive array sensors. The device supports multiple deployment methods with three output mechanisms and offers a wide range of configuration options

characteristic

轮询系统始终保持触控板当前所需位置
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
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
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℃
