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 scaleable 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.
