Analog Devices ADSP-BF52x Blackfin Processors

The ADSP-BF52x processors offer system designers a breadth of choice with a high-performance/low-power series (ADSP-BF527/BF525/BF522) operating at 600MHz, and an ultra-low-power series running at up to 400MHz. All incorporate Blackfin Lockbox Secure Technology(TM) to provide capabilities for implementing the next generation of security — for uses that range from safeguarding intellectual property to protected e-commerce and social networking — on digital media devices.

Options for integrated system peripherals on the Blackfin ADSP-BF52x include High Speed USB On-The-Go (OTG), 10/100 Ethernet, host DMA port, NAND flash controller, up to 48 general-purpose I/O (GPIO) ports, and more. Additionally, ADSP-BF527C/BF525C/BF522C versions feature an embedded, low-power stereo audio codec for use in space-constrained applications such as PMPs and IP phones.

The BF52x family incorporates Lockbox Secure Technology, a combination of hardware and software mechanisms that provide the means for developers to implement security measures that range from safeguarding secrets such as OEMs’ intellectual property, to verifying the identity of devices and users for protected e-commerce and social networking, to digital rights management (DRM) content protection.

Lockbox Secure Technology provides one-time programmable (OTP) memory and a secure processing mode (Blackfin Secure Mode) to enable these capabilities. Its public, non-secure, user-programmable area of OTP memory is suited for storing public keys to authenticate the system in a manner that is controllable and configurable by the developer. A private, secure, user-programmable area of OTP memory lets developers program their own private device assets such as private keys, and maintain the confidentiality and integrity of those assets. In addition, using Secure Mode on Blackfin allows systems to be implemented in which only authenticated, trusted code is allowed to execute on the processor within a secure processing environment.

The ADSP-52x family will range from the ADSP-BF527 at 600MHz for $14.50, to the 300MHz version of the ADSP-BF522L for $5.50. All prices are based on 10,000-unit quantities.
