ADSP-BF702KCPZ-3

Digital Signal Processor Dsp Overview

The ADSP-BF702KCPZ-3 is a Blackfin+ embedded processor from Analog Devices, operating at a maximum clock frequency of 400 MHz. It features a single-core architecture with 136 kB of L1 SRAM (64 kB instruction, 64 kB data, 8 kB scratchpad) and 512 kB of ECC-protected L2 SRAM. The device includes 512 kB of on-chip L2 ROM and supports up to 1 MB of external DDR2/LPDDR memory via the L3 interface. Key peripherals include two CAN controllers, USB 2.0 HS OTG, Quad SPI, and two SPORT interfaces. It is housed in an 88-lead LFCSP_VQ package.

Digital Signal Processor Dsp Feature Summary

• Blackfin+ core delivering up to 400 MHz performance with dual 16-bit or single 32-bit MAC support per cycle.
• Integrated 512 kB L2 SRAM with ECC protection and 512 kB L2 ROM for boot code and security.
• Comprehensive peripheral set including dual CAN, USB 2.0 HS OTG, Quad SPI, and two SPORT interfaces.
• Low power consumption with less than 100 mW core domain power at 400 MHz.

Digital Signal Processor Dsp Applications

• Automotive systems requiring AEC-Q100 qualified components.
• Embedded industrial control and instrumentation.
• Video and image analysis applications.
• Biometric and power/motor control systems.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade and package configuration against the official Analog Devices ordering guide. Confirm that the K suffix corresponds to the 400 MHz variant and the C indicates the 88-lead LFCSP package. Ensure compliance with RoHS standards and check for any recent Product Change Notices affecting availability or specifications.

Digital Signal Processor Dsp Selection Notes

Select this model when 400 MHz processing speed and 512 kB of internal L2 SRAM are required. The 88-lead LFCSP package is suitable for space-constrained designs. Consider the ADSP-BF702BCPZ-3 if a lower speed grade is acceptable, or the ADSP-BF702KCZ-3 if the 184-ball CSP_BGA package with L3 interface support is needed for larger external memory configurations.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-BF70x family of Blackfin+ processors. The BF702 variant specifically offers 512 kB of L2 SRAM and supports a maximum frequency of 400 MHz. It shares the same architectural foundation as other members like the BF700 and BF701 but provides enhanced memory capacity compared to the BF700.

Digital Signal Processor Dsp Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the official Analog Devices selection guide for compatible alternatives within the Blackfin+ family based on specific memory and pinout requirements.
