ADSP-BF524:  Low Power Blackfin Processor with Advanced Peripherals and Low Standby Power

Product Description

The ADSP-BF524 offers up to 400 MHz performance and up to 800 MMACs. This processor core is supported by an advanced DMA controller supporting one-and two-dimensional DMA transfers between on-chip memory, off-chip memory, and system peripherals. The combination of the processor core speed and the DMA controller allows for efficient processing of audio, voice, video, and image data.

The ADSP-BF524 provides peripheral flexibility to complement its high performance processing. The HS USB OTG host direct memory access (HDMA) and NAND flash controller are just a few of the peripheral options on the ADSP-BF524 family—not to mention the availability of up to 48 GPIO pins.

For applications where product differentiation represents a challenge for securing market leadership, the ADSP-BF524 enables developers to provide features and benefits to augment their product offerings without compromising cost or power. The scalability of the ADSP-BF524 makes it an ideal candidate for Premium Audio Players where differentiation of features can be realized without sacrificing system cost. Where the diversity of Multimedia applications and content security are key attributes the ADSP-BF524 provides processing flexibility and Lockbox™ Secure Technology to enable users to develop freely and without bounds.

IP protection has become a necessary part of today’s embedded computing applications. The ADSP-BF524 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.
