ADSP-BF707BBCZ-4

Digital Signal Processor Dsp Overview

The ADSP-BF707BBCZ-4 is a Blackfin+ embedded processor from Analog Devices, operating at a maximum clock frequency of 400 MHz. It utilizes a 184-ball CSP_BGA package and supports 16-bit and 32-bit data processing. The device integrates 136 kB of L1 SRAM, comprising 64 kB instruction memory, 64 kB data memory, and 8 kB scratchpad. It features up to 1 MB of ECC-protected L2 SRAM and 512 kB of on-chip L2 ROM. The processor includes an L3 interface for external DDR2 or LPDDR memory and delivers up to 800 MMACS performance with static power consumption under 100 mW.

Digital Signal Processor Dsp Feature Summary

• Integrated 1 MB L2 SRAM with ECC protection and 512 kB L2 ROM
• L3 interface optimized for low-power connection to DDR2 or LPDDR devices
• Hardware crypto accelerators for secure boot and runtime encryption

Digital Signal Processor Dsp Applications

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

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., -4) against the manufacturer's current ordering guide to ensure the correct 400 MHz performance tier. Confirm that the BGA-184 package variant matches the design requirements, as other packages like LFCSP are available for different pin counts. Check for AEC-Q100 automotive qualification status if the application requires it.

Digital Signal Processor Dsp Selection Notes

Select this model when high signal processing performance is required alongside low power consumption. The 1 MB L2 SRAM reduces the need for external memory in many designs. Ensure the system design accommodates the 184-ball BGA package constraints. Consider the security features if IP protection or secure boot is a requirement for the final product.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-BF70x Blackfin+ family, which serves as an upgrade to previous Blackfin series with enhanced computational capabilities. It shares architectural similarities with models like the ADSP-BF707KBCZ-4 but differs in memory configuration and package type. The BF707 represents the flagship of the series with maximum memory integration.
