Sensing machine gains ICE support
Xemics and Phyton have released the first in-circuit emulator (ICE) for the XE8000 microcontroller series and sensing machines.
Microcontroller takes on smart radio applications
New from Xemics the XE88LC06 is a microcontroller for smart radio applications.
A solution to this is a wireless headset.
Now that "hands free" mobile phone use in cars is a legal requirement in many countries, wireless headsets can comfortably provide the complete freedom of movement and mobility needed both in the car and the office.
With its small form factor the new EZPhone earpiece from Atoz sits comfortably on either ear, while the dongle is plugged into the handset.
The lightweight stylish design mean that hands free communication can be both comfortable and safe.
The EZPhone is easy to use and wear, and its low power consumption means it is easy on the battery.
This solution can be used with existing mobile phones, it is a low cost 'plug 'n play' type device.
The EZPhone wireless headset incorporates Xemics XE1201A ultra-low-power RF devices.
The design is a joint development between Atoz and UnIvations and includes software and hardware designs licensed from UnIvations.
The design was derived from the XM1201A reference module for the RF front-end design and includes a 16bit microcontroller, an ADC, a DAC, amplifiers and power regulators.
A perceived full-duplex audio link between the cell phone and the ear piece covers a distance of 3 to 5m with an average current consumption during operation of 12mA measured at 3.6V.
With a talk time of 5h and a standby time of up to 100h the EZPhone takes full advantage of the XE1201A's low power functionality.
The dongle basestation and the headset are assigned a unique ID to provide a secure communication link.
