MPR083 OVERVIEW
The MPR083 is an Inter-Integrated Circuit Communication (I2C) driven
Capacitive Touch Sensor Controller, optimized to manage an 8-position
rotary shaped capacitive array. The device can accommodate a wide
range of implementations through 3 output mechanisms, and many
configurable options.
Features
1.8 V to 3.6 V operation
41 A average supply current with 1 s response time
2 A 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 polling-
based 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
