The Knowles Corporation have extended their range of surface mount MEMs (micro-electro-mechanical system) microphones to include a new model sensitive to ultrasonic frequencies. The company anticipate that the SPH0641LU4H-1 sensor will play an important role in the development of gesture control systems used for smartphones, tablets and other mobile devices.

Tiny TCVCXO gets close to oven–controlled crystal stability
IQD frequency products have introduced a new range of temperature compensated voltage controlled crystal oscillators (TCVCXO) in a miniature 8-pad 5 x 3.2 mm outline. The IQXT-210 series TCVCXO, offers frequency stability down to ±0.14ppm over the full industrial temperature range of -40 to 85ºC.
HID Transceiver offers Three Year Battery Life
In a recent press release Cypress Semiconductor are trumpeting their latest fourth-generation ultra-low-power 2.4 GHz WirelessUSB NX transceiver chip type CYRF9935 designed to provide communication links for wireless mice, keyboards, trackpads, remote controls and other Human Interface Devices (HIDs).
Two new Bluetooth Smart SoCs from Broadcom
Broadcom have introduced two new system on chip (SoC) controllers intended for integration into peripheral equipment such as remote controller handsets, keyboards and mice which interface to digital TVs, Over The Top (OTT) boxes, set-top boxes (STBs), PCs and tablets.
The LTC3350 Supercap Ride-through Controller
Intermittent short-term power outages caused by local storms or other transient behavior can play havoc with computer-based systems. A power supply with ride-through capability provides power for a limited time during the outage. The LTC3350 announced recently by Linear Technology is a high current backup controller and system monitor for power supplies using supercapacitors for ride-through energy storage.
Single Chip Rotation Sensor
Allegro MicroSystems have announced the release of its ATS605 range of rotation sensors. This device provides a single chip solution to rotational position sensing of a ferrous gear target. Using three integrated Hall sensors together with Hall interface amplifiers, AGC stage, A/D converter and a synchronous digital controller, the ATS605 is able to accurately resolve the movement of much smaller-toothed cogs than was possible with previous revolution detector solutions.
