Analog Devices Introduces Programmable Flash Memory-Based DSP

Analog Devicesy of flash memory-based embedded digital signal processors (DSP) called DashDSP combine high performance digital control with analog precision and flash memory on a single chip. Designed by <%=company%> (Norwood, MA), DashDSP offers the industry's highest level of integration with the signal conversion, signal processing and memory functions all combined onto a single 28-pin chip. This high-level of integration, along with ADI's development tools, greatly reduces system development time. In addition to faster development time, these highly integrated devices reduce overall system cost and improve system reliability.

Using flash memory with the DSP helps simplify software development and provides in-circuit programmability for reprogramming in the field via software upgrades. With flash memory, customers can make functional improvements without modifying existing hardware. The flash memory access time is under 22 nsec.

DashDSP also eases digital control and flash memory design while eliminating the complexity of precision analog interfacing. It integrates an ADSP-21xx-compatible 16-bit fixed- point DSP core, a three phase 16-bit advanced pulse width modulator, precision analog circuits, including a 10-bit A/D converter, precision voltage reference, current/voltage sensing circuits, a power-on reset, plus a serial communications port and flash memory. They feature 12k bytes of embedded flash memory arranged in three sectors for ease of program development.

The first members of the DashDSP family are designed specifically for a variety of motor types, and are available for sampling today and will begin shipping in high volume in Q1 2000. In the near future, a general-purpose flash-based DSP will be announced to address other embedded control applications in the communications, consumer, and computer markets.
