Xicor® Introduces Industry's First Non-volatile, Digitally Programmable Capacitor X90100
--Eliminates the Need for an On-board Microcontroller to Develop Programmable Tuning Circuits
MILPITAS, California - April 3, 2003 - Xicor, Inc. (Nasdaq: XICO), a leading supplier of high performance mixed-signal integrated circuits, today introduced the X90100 Digitally Programmable Capacitor. The device is designed to replace variable capacitors used to tune the frequency response of electronic systems up to 400MHz. The X90100 can be set to 1 of 32 discrete capacitor steps ranging from 7.5 pF to 14.5 pF in 0.20 pF increments. Once the desired capacitor value is selected via an UP/DOWN interface it is stored in the on-chip EEPROM. The chip also has an integrated Power-On-Recall circuit that will restore the preset capacitor position from nonvolatile memory during power up thus eliminating the need of microcontroller initialization. This reduces the cost of components and manufacturing.
The X90100 can be used in a variety of resonant tuning circuits where the programmable capacitive element provides a means for post-manufacturing trimming. Using the X90100 along with common capacitors allow oscillator and filter designs to be achieved with Q-values greater than 50. This product is targeted at the Communications, Industrial and Consumer markets in applications such as Sensors, RF transceivers and other various tuning applications from DC to 400MHz.
"Xicor's focus is to reduce the cost of manufacturing post-trim by providing a standalone solution that does not require a resident microcontroller on board to select a desired capacitor value," stated Tony Ochoa, marketing manager of Linear Products. "These devices allow for a 'set-and-forget' approach by offering a non-volatile, in-circuit programmable capacitive element that only requires a three-pin interface. The excellent linearity and power-up recall of the capacitor setting are powerful features allowing exact and permanent circuit adjustment."
Production samples are available in 8-lead MSOP packaging with 1K unit prices starting at $1.05 USD.
