Overview

Features and Benefits

  • Performance to 400MHz/800MMACs enables multi-channel audio plus CIF video processing in multimedia applications
  • Enhanced Dynamic Power Management with on-chip core voltage regulation allows operation to 0.8V extending battery life in portable applications
  • Application-tuned peripherals provide glueless connectivity to general purpose converters in data acquisition applications
  • Multiple low cost, pin- and code-compatible derivatives enable software differentiation in cost-sensitive consumer applications

Product Details

Analog Devices initial product family, the ADSP-BF531, ADSP-BF532, and ADSP-BF533, offer all the ease of use and architectural attributes of the Blackfin processor. These three processors are all completely pin compatible - differing solely with respect to their performance and on-chip memory - thus reducing risk and offering the ability to scale up or down depending upon the end application needs. All three processors offer low power consumption with scalable performance from low-cost to very high performance.

The ADSP-BF531 is the low cost entry point into the Blackfin Processor family. It offers an optimal balance between performance, peripheral integration, and price and is well suited for the most cost-sensitive applications including portable test equipment, embedded modems, biometrics, and consumer audio.
