Lucent Technologies Introduces Motor Controller Integrated Circuit for Hard Disk Drives; Marks Company's Entry Into Market Segment.Business/Technology Editors ALLENTOWN, Pa.--(BUSINESS WIRE)--Sept. 19, 2000 -- Joins Lucent's line of hard drive electronics for optimized performance, increased integration, "one-stop shopping" Lucent Technologies (NYSE NYSE See: New York Stock Exchange : LU) Microelectronics Group today introduced a high-performance, full-featured motor controller integrated circuit integrated circuit (IC), electronic circuit built on a semiconductor substrate, usually one of single-crystal silicon. The circuit, often called a chip, is packaged in a hermetically sealed case or a nonhermetic plastic capsule, with leads extending from it for (IC) for high- end hard disk drives (HDDs), marking the company's entry into the motor controller market. The new IC joins Lucent's existing line of hard drive electronics - read-channel ICs, preamplifiers and controller circuitry - allowing the company to offer increased levels of integration in the electronic components used in HDD (Hard Disk Drive) See hard disk and HDD caddy. HDD - hard disk drive manufacture, as well as to offer "one-stop shopping." The VC2010 motor controller is targeted at disk drives that operate at 15-thousand revolutions per minute, and is capable of supporting speeds up to 20-thousand revolutions per minute. Such disk drives are deployed in high-end PCs and workstations, Internet servers, and emerging networked storage arrangements such as storage area networks (SANs). The VC2010 controls the spindle motor, which rotates and regulates the speed of disk drive platters, and the voice coil A type of motor used to move the access arm of a disk drive in very small increments. Like the voice coil of a speaker, the amount of current determines the amount of movement. Contrast with stepper motor, which works in fixed increments. actuator, which positions the read/write heads over the data tracks on the platters. The new IC was designed by engineers at the company's Twin Cities Business and Technology Center in Bloomington, Minn. Lucent established the center earlier this year when it acquired the products and the design, marketing and sales teams of VTC VTC - video teleconferencing Inc., which focused on analog semiconductors for the hard drive industry. "Hard drive manufacturers are under relentless pressure to increase the storage capacity and performance of their drives while bringing them to market faster and at competitive prices," said Mark Granahan, general manager of the Analog Products Business in Lucent's Microelectronics Group. "That puts pressure on component suppliers to deliver more value. Not only is our new motor controller a competitive offering in its own right, but by having a full line of hard drive electronics under one roof, we can provide synergies and higher levels of integration - with the convenience of one-stop shopping." The VC2010 features an integrated voice-coil motor (VCM VCM Vinyl Chloride Monomer VCM Variable Cylinder Management (Honda) VCM Virtual Channel Memory VCM Value Chain Management VCM Voice-Coil Motor VCM Vehicle Control Module VCM Vignette Content Management ) compensation loop, enabling on-chip capability to program error compensation. It has a switched capacitor Switched Capacitor is a circuit design technique for discrete time signal processing. It works by moving charges between different capacitors when switches are opened (off) and closed (on).

The spindle control section provides six-state motor commutation using a phase-locked loop A phase-locked loop or phase lock loop (PLL) is an electronic control system that generates a signal that has a fixed relation to the phase of a "reference" signal. A phase-locked loop circuit responds to both the frequency and the phase of the input signals, automatically (PLL PLL - phase-locked loop ) and provides transconductance current control through a 10-bit digital-analog converter (DAC See D/A converter and discretionary access control. DAC - Digital to Analog Converter ), with four ranges. The chip, designed to support a variety of system voltage requirements, includes a minus-five-volt programmable negative switching regulator, a 3.3-volt switching regulator, and two additional programmable positive regulators. Sample quantities of the device are available now, with production quantities slated for the first quarter of 2001. Unit pricing will be US$5 in quantities of 1,000.

Lucent Technologies Microelectronics Group is the world leader in semiconductors for communications applications. Lucent has announced it will spin off the Microelectronics Group as an independent company that will include its optoelectronics and integrated circuits divisions. The spin-off, slated for completion by the summer of 2001, will create the only major stand-alone semiconductor company that can offer end-to-end networking solutions that address the convergence of photonics and electronics based on leadership in both integrated circuits and optoelectronic components. The new company will also provide wireless computer networking system solutions through its ORiNOCO(tm) product line.
