Motion and touch sensing platform

27 October 2010 Analogue, Mixed Signal, LSI

Freescale Semiconductor has introduced its Xtrinsic sensing solutions – products designed with a combination of high-performance sensing capability, processing capacity and customisable software to help deliver smart, differentiated sensing applications. Xtrinsic sensing solutions have built-in intelligence and make complex calculations and decisions within the context of their environments. This offloads the host processor of these extensive processing requirements, enabling more efficient systems.

As one of the first solutions embodying these advanced functions, Freescale has released the intelligent, high-precision Xtrinsic motion sensing platform based on the integration of an accelerometer, processing core, memory and multiple embedded functions. Freescale is also aligning its microcontroller-based touch sensing solutions to the Xtrinsic portfolio. Xtrinsic Touch Sensing Software Suite 2.0 expands capacitive touch sensing capability beyond 8-bit to 32-bit microcontrollers.

The Xtrinsic MMA9550L manages multiple sensor inputs and can perform intelligent, system-level decisions within the application. It extends 3-axis accelerometer functionality with a programmable core and on-chip memory to enable advanced motion sensing capability. Combining attributes including a small 3 x 3 x 1 mm package, 14-bit resolution, low-noise and low-power, the MMA9550L is a highly flexible and configurable sensor decision engine. Up to 12 inputs are consolidated by the sensing hub, which operates with a slave port configurable as either IIC or SPI allowing calibration, compensation and sensor functions to be offloaded from the system applications processor.
