Freescale sensor compatible with 300 of its MCUs

Freescale's second-generation MPR121 capacitive touch sensor provides reliable touch detection through increased electrode count and integration of automatic calibration and area detection systems.

The 12-pad touch sensor is available in the industry's smallest lead-free package and offers the lowest power consumption at 29uA average supply current.

Suitable for portable, low-power consumer electronics applications, the MPR121 touch sensor has been selected to enable compelling features for the newest MP3 players from Audiovox.

The TSS suite provides an alternate solution by enabling the integration of touch sensing functionality into applications based on Freescale eight-bit MCUs.

The suite speeds development by delivering pre-configured software that enables a range of features including rotary, slider and keypad functionality.

The software also eliminates the need for additional sensor silicon in many designs.

Freescale's portfolio of touch sensing solutions allows customers to select the option that meets their specific system requirements for power, software integration and quantity of touch points.

Customers can choose a three- or 12-pad Freescale sensor or the touch-sensing software solution for a variety of applications.

These include home appliances such as cooktops, ovens, refrigerators and washing machines; consumer and portable electronics such as media players, audio/video systems, TV sets, PCs, monitors, notebooks, MP3 players and cameras; and medical and industrial equipment including control panels and portable medical devices.

They also include: remote and lighting controls; low-resolution touch screens for photo frames and GPS systems; large and small appliance touch-panel interfaces; mobile phones and wireless connected device touch panels and general use button replacements for netbooks and smartbooks.
