The ADSP-BF522C/BF525C/BF527C Blackfin Processor combines high performance, power efficiency and system integration to enable highly optimized designs without compromises. With built-in peripheral selectivity the BF522/525/527 provides the greatest flexibility for today’s most demanding convergent signal processing applications. With power consumption as low as 0.16 mW/MHz and performance up to 600 MHz, applications can now add greater signal processing performance without forgoing battery life.

ADSP-BF522C/BF525C/BF527C differs from the ADSP-BF522/BF525/BF527 with the addition of an Audio codec.
