Freescale Semiconductor is meeting the demand for touch-sensitive control with the introduction of two sensitive touch pad controllers. Freescale’s MPR081 and MPR082 proximity capacitive touch sensor controllers are designed to detect touch by measuring capacitance. Touch sensors are becoming essential for any interface with buttons. They offer designers a low cost alternative to mechanical push buttons for applications such as access controls, appliances, mobile phones, MP3 players, PC peripherals and remote controls. Replacing traditional push-button interfaces with touch-sensitive control ultimately makes the interface more intuitive and easier to use.
