ADSP-BF523:  Power Blackfin Processor with Advanced Peripherals

Product Description

The ADSP-BF523 Blackfin Processor combines high performance, power efficiency and system integration to enable highly optimized designs without compromises. With built-in peripheral selectivity the BF523 provides the greatest flexibility for today’s most demanding convergent signal processing applications. With power consumption as low as 0.23 mW/MHz and performance up to 600 MHz, applications can now add greater signal processing performance without forgoing battery life.

Configured as a co-processor in applications where flexibility is required to support a variety of multimedia applications, the ADSP-BF523 offers the processing performance along with scaleable power management that provides developers that flexibility in their design. For battery powered applications that either enhance the multimedia experience or deliver a full Mobile TV implementation, the ADSP-BF523 represents the ideal solution to release design innovation.

IP protection has become a necessary part of today’s embedded computing applications. The ADSP-BF523 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.
