ADSP-BF512F:  Low Power Blackfin with Consumer Devices Connectivity

Product Description

The ADSP-BF512F 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. The high performance 16/32-bit Blackfin embedded processor core, the flexible cache architecture, the enhanced DMA subsystem, and the dynamic power management (DPM) functionality allow system designers a flexible platform to address a wide range of applications.

IP protection has become a necessary part of today’s embedded computing applications. The ADSP-BF512F 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.

The BF512F includes an integrated 4Mb serial Flash (SPI) memory alongside the processor.
