• Product introduction

MPR083EJR2   触摸sensor

The MPR083 is a capacitive touch sensor controller with an integrated I2C bus designed to manage 8-position rotary capacitive array sensors. The device supports multiple deployment methods with three output mechanisms and offers a large number of configuration options.

characteristic

• 41μA average operating current, 1s response time
• 2μA standby current
• Variable Low Power Mode Response Time (32ms–4s)
• Rejects multi-key detection caused by EMI events, such as PA bursts or user actions
• EMI events do not reset the trackpad for analysis and monitoring
• Data is buffered by FIFO to minimize access time
• IRQ output recommendations when FIFO has data
• The system can immediately set the interrupt behavior within the shortest event or program interval after a successive interrupt
• The polling system always maintains the current rotation position
• The speaker emits keystrokes when touch-rotated
• Two hardware-selectable I2C addresses allow two devices to be configured on one I2C bus
• The operating temperature range is -40°C to +85°C
