ADSP-BF704KCPZ-4

Digital Signal Processor Dsp Overview

The ADSP-BF704KCPZ-4 is a Blackfin+ embedded processor from Analog Devices, operating at a maximum clock frequency of 400 MHz. It utilizes an 88-Lead LFCSP_VQ package (12 mm × 12 mm). The device integrates 136 kB of L1 SRAM with multi-parity-bit protection and 512 kB of ECC-protected L2 SRAM. It features a dual 16-bit or single 32-bit MAC support per cycle, along with crypto hardware accelerators for secure boot and data encryption. The processor supports AEC-Q100 automotive qualification and operates within a core voltage range of 1.1 V to 1.47 V.

Digital Signal Processor Dsp Feature Summary

• Blackfin+ core with up to 400 MHz performance and instruction set compatibility with previous Blackfin products
• Integrated memory architecture including 136 kB L1 SRAM and 512 kB ECC-protected L2 SRAM
• AEC-Q100 qualified for automotive applications with low system power consumption (< 100 mW core domain power at 400 MHz)
• Comprehensive peripheral set including USB 2.0 HS OTG, 2× CAN, 2× SPORT, and Quad SPI interfaces

Digital Signal Processor Dsp Applications

• Automotive systems requiring AEC-Q100 compliance
• 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 suffix KCPZ-4 against the manufacturer's ordering guide to confirm package type and speed grade. Ensure that the procurement source provides valid RoHS compliance documentation. Check for any recent Product Change Notices (PCN) regarding die revision or assembly changes that may affect long-term availability or pin compatibility.

Digital Signal Processor Dsp Selection Notes

Select this model when 512 kB of on-chip L2 SRAM is sufficient for the application, distinguishing it from variants with 256 kB or 1 MB capacities. The 88-Lead LFCSP package is suitable for space-constrained designs compared to the 184-Ball CSP_BGA option. Confirm that the system design supports the required I/O voltages of 1.8 V and 3.3 V for peripheral interfacing.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-BF70x series, which offers scalable memory options ranging from 128 kB to 1 MB of L2 SRAM. The BF704 variant specifically provides a mid-range memory configuration within the Blackfin+ family. It shares the same core architecture and peripheral interface capabilities as other members in the BF700 through BF707 lineup, differing primarily in internal memory size and GPIO count.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same package include the ADSP-BF703KCPZ-4 (256 kB L2 SRAM) and the ADSP-BF705KCPZ-4 (1 MB L2 SRAM), provided the memory requirements can be adjusted. Cross-package replacements such as the 184-Ball CSP_BGA variants require PCB redesign due to different pin counts and form factors.
