Processor Offers Power Efficiency, Security for Portable, Networked Applications
Analog Devices expandr its Blackfin line with the ADSP-BF52x family, a scalable series of processors for portable applications. Using the Dynamic Power Management capabilities of Blackfin to achieve power efficiency as low as 0.16 mW/MHz core power at 250 MHz, these processors offer system designers a wide choice with a high-performance/low-power series (ADSP-BF527/BF525/BF522) operating at 600 MHz, and an ultra-low-power series running at up to 400 MHz. All incorporate Blackfin Lockbox Secure Technology for security uses such as safeguarding IP 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 and up to 48 general-purpose I/O (GPIO) ports. The ADSP-BF527C/BF525C/BF522C versions feature an embedded, low-power stereo audio codec. An internal voltage regulator and process improvements help scale power consumption on-chip to match the MIPS necessary for the function being executed at the time.
