MPR084 OVERVIEW  
MPR084  
Capacitive Touch  
Sensor Controller  
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.

1.8 V to 3.6 V operation  
41 µA average supply current with 1 s response time  
2 µA low 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  
16-LEAD QFN  
CASE 1679

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 touched pad position is always available on demand for  
polling-based systems
