ADSP-BF522:  Low Power Blackfin Processor with Advanced Peripherals and Low Standby Power

Product Description

The ADSP-BF522 Blackfin Processor combines high performance, power efficiency and system integration to enable highly optimized designs without compromises. With built-in peripheral selectivity the BF522 provides the greatest flexibility for today’s most demanding convergent signal processing applications.

For battery powered applications that either enhance the multimedia experience or deliver a full Mobile TV implementation, the ADSP-BF522 represents the ideal solution to release design innovation.

IP protection has become a necessary part of today’s embedded computing applications. The ADSP-BF522 provides a security scheme which balances flexibility and upgradeability with performance through the inclusion of a firmware-based solution including OTP (One Time Programmable) memory to enable users to implement private keys for secure access to program code.
