ADSP-BF531SBBCZ400

Digital Signal Processor Dsp Overview

The ADSP-BF531SBBCZ400 is a Blackfin embedded processor from Analog Devices, operating at a maximum clock frequency of 400 MHz. It features a dual-MAC signal processing engine with two 16-bit multipliers and two 40-bit accumulators. The device includes up to 52 KB of on-chip L1 memory, configurable as SRAM or cache, along with a 4 KB scratchpad SRAM. It utilizes a 160-ball CSP_BGA package and supports a wide range of operating voltages via an on-chip programmable voltage regulator.

• Consumer audio applications

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'BBCZ' against the manufacturer's ordering guide to confirm package type (CSP_BGA), temperature range, and lead-free status. Confirm availability through authorized distributors as this component may be subject to end-of-life notices within the Blackfin family.

Digital Signal Processor Dsp Selection Notes

Select the ADSP-BF531SBBCZ400 when code and pin compatibility with the BF532/BF533 series is required but lower on-chip memory capacity is sufficient. Ensure the design accommodates the 160-ball CSP_BGA footprint and provides adequate thermal dissipation for the 400 MHz operation.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-BF531/ADSP-BF532/ADSP-BF533 family, which shares identical pinouts and instruction sets. The BF531 variant offers the lowest on-chip memory configuration among the three, making it suitable for cost-sensitive applications where external memory expansion is acceptable.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-BF532 and ADSP-BF533 are pin-compatible upgrades offering higher memory capacities. For direct replacement in existing designs, verify that the increased memory does not cause address mapping conflicts if the software relies on specific memory boundaries.
