Analog Devices DSP is First Motor Control Solution to Integrate Current Sensing


NewDashDSP family members reduce system component count by 30%.

NORWOOD, Mass., Nov. 12 /PRNewswire/ -- Analog Devices, Inc. (NYSE: ADI) today announced a new series of DashDSP digital signal processors for motor control applications. The ADMCF34x series features enhanced motor current sensing integration that enables a 30 percent reduction in system component count and control bill of materials cost. These new devices are the first embedded DSP controllers to offer this high level of mixed-signal integration for motor current sensing. ADI is the leading innovator in the field of motor control, where the combination of DSP control and mixed-signal integration enables increased energy efficiency, reduced noise and improved reliability in the final application. "The second generation of the DashDSP motor control products from Analog Devices reaffirms Analog Devices' commitment to the cost-sensitive motor control markets in white goods and industrial applications," said Eric Wildi, vice president of new business development, Emerson Corporation. "The enhanced mixed-signal integration of the ADMCF34x devices, combined with the DSP processor core and on-chip flash memory enables us to further reduce system costs by taking advantage of the integration in these devices."

"With the introduction of our new ADMCF34x series, ADI's DashDSP family continues to provide appliance and industrial manufacturers with the highest levels of IC integration which translates into significant system cost savings while delivering best-in-class performance," said Dr. Finbarr Moynihan, product line manager, Motor Control Solutions Analog Devices. "In addition, these embedded DSP solutions provide the system designer with a great deal of flexibility as manufacturers can now easily make system improvements in software without the need to modify existing hardware."

About ADI's ADMCF34x Series of DashDSP Solutions
ADI's ADMCF34x family features an enhanced analog front end that integrates bipolar current sense amplifiers with programmable sample - and-hold capability for simultaneous sampling of up to three channels. The ADMCF340 and ADMCF341 are offered in flash memory versions and pin- compatible lower-cost ROM versions that can be used for high volume mass production. All ADMCF34x products are code compatible with the ADMCF32x DashDSPs and ADI's entire family of general purpose ADSP-21xx 16-bit, fixed-point DSPs. On-chip motor control peripherals are optimized for sensorless or sensor control of multi-phase motors and include: a three-phase PWM generation unit, dual auxiliary PWM timer outputs and serial ports with SPI support.

The ADMCF340 features 13 analog channels, including three current sense inputs, and 25 digital I/O channels for use with permanent magnet brushless dc, ac induction, permanent magnet synchronous and switched reluctance motors. The ADMCF341 is a 28-lead SOIC product with 6 analog channels, including three current sense inputs, 3 voltage inputs, and 9 digital I/O channels targeted at permanent magnet brushless, permanent magnet synchronous and ac induction motors.

Pricing and Availability
Development kits are available now for $395. Samples of the ADMCF34x products are available now with ROM versions to follow in early 2002. OEM pricing in 10,000 unit quantities is $10.25 for the ADMCF340 and $9.25 for the ADMCF341. ROM products will be offered in OEM quantities at $3.50.
