Controller 16-Pin TSSOP Rail

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.

41 uA average supply current with 1 s response time

2 uA 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

-40° C to +85° C operating temperature range

5 mm x 5 mm x 1 mm 16 lead QFN package

Configurable real-time auto calibration>

Pb-Free and RoHS compliant
