&& PREVIOUS FINALIST | MAIN | NEXT FINALIST >> Category: Passive Components and Sensors Finalist: MPR03x proximity-sensor controllers (Freescale Semiconductor)  Freescale's MPR03x proximity sensor controllers simplify the design of touch-sensing interfaces. Embedded developers require design simplicity and power conservation in a small form factor for compact system designs. The MPR03x solutions replace mechanical buttons, switches and other moving parts that typically wear out and are less reliable.The MPR03x devices operate at extremely low power at 8 microamps average supply current in full run mode. The MPR031 and MPR032 touch sensors enable low power consumption and advanced touch sensing within an extremely small form factor (2x2x0.65mm in a uDFN) 8-pin package with only one external passive component. Portable consumer electronics and button replacement applications with limited real estate require highly compact controllers such as the MPR03x devices. In addition to compact size and low-power operation, the MPR03x devices are among the easiest to use and implement in touch sensing applications. The intelligent touch detection and filtering capabilities of the MPR03x sensors make them ideal for first-time users of touch sensors looking for a simple implementation. While many devices on the market require complex software understanding and quite a bit of overhead, the easy-to-use MPR03x devices calculate and deliver touches internally with no software interaction required. When a touch begins or ends, an interrupt will be sent to the host system signifying a change in state; then with a single I2C command, the host system can determine what key or keys are pressed. |
