DEMOMPR083

The DEMOMPR083 is an demo board for MPR083. 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.

• Sample electrode board demonstrates rotational sliders
• Machined plastic cover for front panel non-contact touch evaluation
• Access to all 8 electrodes
• 41μA average supply current with 1sec response time
• Variable low power mode response time (32ms to 4sec)
• 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
• Current rotary position is always available on demand for polling based systems
