MPR084EJ General Description

The MPR084 is an Inter-Integrated Circuit Communication (I2C) driven Capacitive Touch Sensor Controller, optimized to manage an 8-touch pad capacitive array. The device can accommodate a wide range of implementations through 3 output mechanisms, and many configurable options.

Key Features

• 1.8 V to 3.6 V operation
• 41 µA average supply current with 1 s response time
• 2 µA Standby Current
• Variable low power mode response time (32 ms – 4 s)
• Rejects unwanted multi-key detections from EMI events such as PA
bursts or user handling
• Ongoing pad analysis and detection is not reset by EMI events
• Data is buffered in a FIFO for shortest access time
• IRQ output advises when FIFO has data
• System can set interrupt behavior as immediate after event, or
program a minimum time between successive interrupts
• Current rotary position is always available on demand for pollingbased systems
• Sounder output can be enabled to generate key-click sound when
rotary is touched
• Two hardware selectable I2C addresses allowing two devices on a
single I2C bus
• Configurable real-time auto calibration
• 5 mm x 5 mm x 1 mm 16 lead QFN package
• -40°C to +85°C operating temperature range
