Freescale Continues Advances in 3D Accelerometers and Touch Sensors

Last week Freescale announced its latest 3D Accelerometer (MMA7450L) and new Proximity Capacitive Touch Sensor Controllers (MPR081/2).

The MMA7450L is Freescale’s first accelerometer with digital output. It provides three levels of g-level selection and a freefall detect pin. Freescale is offering this in a smaller package and with lower current consumption. The goal is to match this with Freescale’s i.MX processor, a smart phone application processor. Freescale is sampling now and production is slated for August 2007.

The MPR081 is designed a rotary 16 position touch sensor, the sort that is used for MP3 players. The MPR082 is a controller for a touchpad that is a matrix with up to 20 keypads. These controllers provide a digital output and are based on a low-voltage, low current technology. The MPR081 is sampling June 2007 and in production October 2007. The MPR082 will sample in August 2007 and in production 4Q 2007.
