Blackfin DSPs upgraded for industrial imaging, audio and automotive

June 12, 2014 // By Nick Flaherty
Analog Devices has upgraded its Blackfin DSP processor family to provide 800 MMACS of processing power at less than 100 mW.

The eight-member Blackfin ADSP-BF70x family includes up to 1 MB of internal SRAM, eliminating external memory in many applications, while a second configuration features an optional DDR memory interface. The combination of performance, power efficiency, integration and value allows designers to incorporate 16- and 32-bit processing in a range of new embedded vision use cases, including industrial imaging and building controls as well as portable and automotive audio.
The ADSP-BF70x family offers designers' flexibility and functionality through connectivity with USB, SDIO, CAN, ePPI, SPORT and QuadSPI while enabling power sensitive bus-powered applications and extending the life of battery-powered devices.

“The ADSP-B70x Blackfin family provides a scalable design approach for commercial-, industrial- and automotive-grade equipment where systems engineers must maintain high performance while designing for environmental regulations, portability, extended battery life and shrinking power budgets,” said Andy Lanfear, product marketing manager at Analog Devices. “Our latest processor line extends ADI’s leadership position for high-performance, ultra-low-power DSPs by delivering up to 400 MHz with single-cycle, dual-16-bit, 32-bit and complex fixed-point math capability – all while operating on a 95-mW core power budget.”

The ADSP-BF70x Blackfin processors are designed for a range of industrial and building automation applications, including intelligent lighting and occupancy sensing and industrial imaging in cameras, barcode readers and biometric sensors. The processor family’s low-power consumption, new 32-bit math and large on-chip SRAM also suits it to portable audio and automotive audio, where deterministic real-time processing is critical for high-fidelity sound.

With software IP protection a growing industry security concern, the ADSP-B70x Blackfin processor family additionally includes an onboard crypto hardware accelerator that features fast secure boot with decryption and authentication. For always-on safety critical applications, the BF70x series also provides high data integrity with parity and error-correction code (ECC)-protected memory circuitry.

Blackfin processors are available in single 12 × 12 QFN or 12 × 12 BGA packages starting at under $4.00/1k units.
