Small boast for digitally controlled
potentiometer
The X93154 is claimed as the world's smallest digitally controlled potentiometer.
The X93154 is claimed as the world's smallest digitally controlled potentiometer (DCP) Offered in both an industry standard MSOP and a flip-chip package with a footprint of only 1mm2, with its small form factor, competitive pricing, and ultralow power consumption, the X93154 addresses new market needs for high volume and space constrained applications such as portable or personal communications devices

Clock chip takes on supervisory functions
Xicor has added two new members to its integrated real time clock (RTC) product family.
Reference design makes for powerful basestations
Xicor has teamed up with Motorola to provide radio-frequency power amplifier (RFPA) reference platforms for GSM, Edge and W-CDMA cellular basestation applications.
The X93154 family is a 32-tap potentiometer with a total resistance of 50kohm.
Along with dissipating ultra low power at 1uA maximum standby supply current, the X93154 achieves less than +/-0.2LSB typical differential nonlinearity.
The integration of nonvolatile memory for the wiper position provides design advantages over one-time-programmable or volatile solutions including lower programming current and the elimination of additional high voltage supplies required by one-time-programmable products.
The simple up/down interface can be used for personalised environments such as LCD contrast and backlight brightness control in cellphones, PDAs and GPS receivers.
The small form factor and reprogrammability are key components in systems requiring gain, reference voltage and bias calibrations such as common mode amplifier biasing and feedback gain adjustments.
Other target applications include process controls requiring parameter retention and data acquisition systems requiring preconfigured reference voltage levels.
Flexibility and adaptability are key components needed to satisfy the high level of integration in today's systems.
By using a new process technology, the X93154 integrates small form factor and competitive pricing to provide an ideal solution to high volume applications, replacing outdated mechanical potentiometers and precision resistors.
Production samples are available in 8-lead MSOP and FCP packaging.
