New process provides ultra-stable
references
A new floating gate analogue technology is being used for the development of a family of ultra-low-power precision voltage references.
Xicor has unveiled a new floating gate analogue (FGA) technology that is being used for the development of a family of ultra-low-power precision voltage references FGA technology is an extension of an existing Xicor proprietary, nonvolatile technology that capitalises on the extraordinary capabilities of thick-oxide Fowler-Nordheim tunnelling devices to retain a precision charge level on floating gate devices

Digital pots aim for space saving applications
The X93155 and X93255 ultra-low-power digitally controlled potentiometers address new market needs for high volume and space constrained applications.
High-accuracy reference targets portable uses
The X60008A-50 is an extremely stable, highly accurate, low-power 5V voltage reference that is ideal for use in battery powered high-resolution data-acquisition systems.
Using this technical strength, Xicor achieves overall voltage reference performance far beyond that of existing conventional analogue technologies.
By storing the reference voltage on a floating gate, Xicor is able to produce precision voltage references that feature exceptional initial accuracy, temperature coefficient and long-term stability with extremely low supply current.
The performance of these products surpasses many of the most accurate voltage references currently available.

Reference boosts performance but cuts costs
The X60008EIS8-50 is the latest addition to the Xicor family of precision voltage references manufactured using the company's proprietary FGA floating gate analogue technology.
The initial accuracy is as low as 250uV (A Grade), demonstrating the ability of the FGA technology to set the floating gate charge precisely.
The impact of temperature variations is as low as 1ppm/C (A Grade) due to the low temperature coefficient of the FGA devices.
Very low drift over time is a direct result of the extremely low charge loss from the thick oxide floating-gate.
Special analogue techniques allow circuit operation with only 500nA supply current and consequently provide an ideal solution for precision and battery-powered applications.
Precision voltage references manufactured using conventional approaches such as buried-zener and bandgap devices have difficulty achieving 1mV initial accuracy and 5ppm/C temperature coefficient.
As a result, voltage reference products that exceed this performance are expensive and limited, potentially restricting system performance.
Unlike more conventional nonvolatile memory technologies that use thin tunnel oxides, Xicor's proprietary FGA technology allows larger voltages on the floating-gate and in turn improves the initial accuracy and temperature coefficient and reduces drift over time.
The first devices in the voltage reference product line are pin-compatible with industry standard products and feature very high initial accuracy, very low temperature coefficient, excellent long-term stability, low noise, excellent line and load regulation and the lowest power consumption currently available (typical 500nA supply current).
These voltage references enable advanced applications for precision industrial and portable systems operating at significantly higher accuracy and lower power levels than can be achieved with conventional technologies.
Engineering samples are currently available for the X60008CS8-5 (C Grade, SO-8 package) voltage references.
Production volumes will be available later in the second quarter.
Xicor expects additional product introductions throughout the year including the X60003 (SOT-23) along with the X60038 and X60033 products that are targeted at applications requiring fast transient response.
A variety of other voltage options down to 0.9000V will also be available.
