ADSP-BF704BCPZ-4

Digital Signal Processor Dsp Overview

The ADSP-BF704BCPZ-4 is a single-core Blackfin+ digital signal processor from Analog Devices, operating at a maximum clock frequency of 400 MHz. It utilizes an 88-Lead LFCSP_VQ package with dimensions of 12 mm × 12 mm. The device integrates 136 kB of L1 SRAM, comprising 64 kB instruction memory, 64 kB data memory, and 8 kB scratchpad. On-chip L2 memory consists of 512 kB of ECC-protected SRAM and 512 kB of ROM. Core power consumption is less than 100 mW at 400 MHz. The processor supports dual 16-bit or single 32-bit MAC operations per cycle.

Digital Signal Processor Dsp Feature Summary

• Blackfin+ core supporting up to 400 MHz performance with dual 16-bit or single 32-bit MAC capabilities.
• Integrated 512 kB ECC-protected L2 SRAM and 512 kB on-chip L2 ROM.
• AEC-Q100 qualified for automotive applications with low static power consumption.
• Rich peripheral set including USB 2.0 HS OTG, two CAN interfaces, and Quad SPI.

Digital Signal Processor Dsp Applications

• Automotive systems
• Embedded industrial instrumentation
• Video and image analysis
• Biometric applications
• Power and motor control

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade and package configuration against the official Analog Devices ordering guide. Confirm RoHS compliance and AEC-Q100 automotive qualification status as required by the application environment. Ensure ESD handling procedures are followed due to moisture sensitivity.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-performance signal processing within a strict power budget under 100 mW. The 512 kB L2 SRAM variant suits designs needing substantial on-chip memory without external RAM. Verify that the 88-lead LFCSP package fits the PCB footprint constraints.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-BF70x family, which includes variants ranging from 128 kB to 1 MB of L2 SRAM. The BF704 specifically provides 512 kB of L2 memory. It shares the same core architecture and peripheral set as other members in the series, differing primarily in memory capacity and speed grades.

Digital Signal Processor Dsp Replacement Considerations

Other models in the ADSP-BF70x series, such as the ADSP-BF703 or ADSP-BF705, offer different L2 SRAM capacities (256 kB or 1 MB) but maintain pin compatibility within the same package type. Check the specific memory requirements before substituting.
