Blackfin ADSP-BF70x
Series of DSP Processors
Industry’s Performance Leading
Ultralow Power DSP Solution
Overview
Target Applications Include
The new ADSP-BF70x Blackfin® processor series is a high performance DSP that delivers a
class leading 800 MMACS of processing power at less than 100 mW. The cost-effective
eight member series includes up to 1 MB of internal L2 SRAM, eliminating external memory in
many applications, while a second configuration features an optional DDR2/LPDDR memory
interface. Using the enhanced Blackfin+ core, the combination of performance, power efficiency,
memory integration, security, and value allows designers to incorporate advanced 16- and 32-bit
fixed-point processing into a range of new use cases, including industrial imaging and building
controls as well as portable and automotive audio. The ADSP-BF70x series offers designers
unparalleled flexibility and functionality through an array of advanced connectivity options
(including USB, SDIO, CAN, ePPI, SPORT, QuadSPI) while enabling bus-powered applications
and extending the life of battery-powered devices.
