Product Preview Proximity Capacitive Touch Sensor Controller 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 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 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 Implementations • Control Panels • Switch Replacements • Rotary and Linear Sliders Typical Applications • Appliances • PC Peripherals • Access Controls • MP3 Players • Remote Controls • Mobile Phones ORDERING INFORMATION Device Name Temperature Range Case Number Rotary Slider MPR083Q -40 °C to +85°C 1679 (16-Lead QFN) 8-Positions MPR083EJ 948F (16-Lead TSSOP) E5 E6 E7 E8 VDD VSS ATTN IRQ MPR083 3 4 1 2 10 9 12 11 78 56 14 13 16 15 MPR083 Capacitive Touch Sensor Controller 16-LEAD TSSOP CASE 948F Top View Figure 1.
