ADSP-BF531SBBZ400

Digital Signal Processor Dsp Overview

The ADSP-BF531SBBZ400 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 52 KB of on-chip L1 memory, configurable as instruction SRAM/cache and data SRAM/cache, along with a 4 KB scratchpad SRAM. It utilizes a 169-ball PBGA package and supports a core voltage of 1.2 V. Integrated peripherals include two synchronous serial ports (SPORTs), a UART, an SPI port, three timers, a real-time clock, and a watchdog timer.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'SBBZ' against the manufacturer's ordering guide to confirm package type (169-ball PBGA) and temperature range. Confirm availability status as this component may be subject to discontinuation or supply constraints. Ensure compatibility with existing PCB footprints for the 169-ball PBGA package.

Digital Signal Processor Dsp Selection Notes

Select the ADSP-BF531SBBZ400 when cost-sensitive applications require 400 MHz performance with 52 KB of on-chip memory. Compare against ADSP-BF532 and ADSP-BF533 variants if higher memory capacity or faster clock speeds are needed, noting that all three are pin-compatible. Consider the 169-ball PBGA package constraints for board layout.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-BF531/ADSP-BF532/ADSP-BF533 family of Blackfin processors. These devices are code and pin-compatible, differing primarily in on-chip memory size and maximum operating speed. The BF531 serves as the entry-level option in this series, offering a balance of performance and cost for embedded control and signal processing tasks.

Digital Signal Processor Dsp Replacement Considerations

Pin-compatible alternatives within the same family include the ADSP-BF532 and ADSP-BF533, which offer increased memory or higher clock speeds. Verify software compatibility and memory requirements before substituting.
