Analog Devices Expands Mixed-Signal DSP Family With New Can-Based Device


-Emerson selects ADSP-21992 for its next generation applications.

NORWOOD, Mass.--Analog Devices, Inc. (NYSE: ADI) today announced
availability of the newest member of its advanced family of mixed-signal DSPs that target emerging embedded control and signal processing applications. The ADSP-21992 adds the extra benefits of a CAN (controller area network) interface and additional on-chip random access memory (RAM) to the ADSP-2199x family. These new features target the needs of automotive, industrial motor control, un-interruptible power supply (UPS) and portable instrumentation applications. Like its predecessors, the ADSP-21992 combirnes the C-programmable ADSP-219x core with high-performance analog integration and the award-winning VisualDSP++(TM) development tools. With the ADSP-21992, ADI continues to leverage its deep signal-chain knowledge and core competencies in analog technology to offer the highest dynamic range and fastest sampling rates available on monolithic, general-purpose DSPs. In addition, ADI also announced today Emerson Electric Co. has selected the ADSP-21992 for it next generation applications.

"Emerson is migrating new product development efforts to ADI's new ADSP-2199X DSP family. The performance improvements over ADI's older DSP generations, its C programmability, and the inclusion of a CAN bus interface allow us to markedly shorten new product prototyping and time to market. The features of this new DSP family enable us to efficiently design a wide range of electrically driven motor drive products aimed at replacing traditional mechanical, geared, and hydraulic basedsystems," said Eric Wildi, vice president of new business development,
Emerson Electric.

"The ADSP-21992 is the latest member to our world-class mixed signal DSP family and highlights ADI's leading expertise in high performance analog and digital signal processing technology," said Jerry McGuire, product line director, general purpose DSPs, Analog Devices. "We are pleased that a technology leader like Emerson has once again selected ADI's mixed-signal DSPs."

About ADI's ADSP-21992

The ADSP-21992 integrates a 160 million instructions per second (MIPS), 16-bit, ADSP-219x DSP core with 481 words of on-chip RAM, an 8-channel, 14-bit, 20 million samples per second analog-to-digital converter (ADC) with dual sample-and-hold amplifiers, three-phase PWM generator (suitable for both motor and switching power converter control), incremental encoder interfaces, timers, serial communications ports, SPI interface, watchdog timers and interrupt controllers.

The CAN interface on the ADSP-21992 conforms to CAN V2.0B and includes standard (11-bit) and extended (29-bit) identifiers. It has a 1 Mbit/sec data rate and 16 configurable mail boxes (all receive or transmit). Other features of the CAN interface on the ADSP-21992 include error status and warning registers, a universal counter module, powerdown/sleep mode and readable transmit and receive counters.

The ADSP-21992 is supported by ADI's CROSSCORE(TM) hardware and
software development tools. Samples of the ADSP-21992 are available now with production scheduled for 4Q2002. Pricing is $22.50 per unit in quantities of 10,000-units. The ADSP-21992 will be available in a 196-ball, mini-BGA package and a 176-pin TQFP package. The full industrial temperature range of -40 degrees C to +85 degrees C is supported.
