ADSP-BF532SBSTZ400

Digital Signal Processor Dsp Overview

The ADSP-BF532SBSTZ400 is a Blackfin embedded processor from Analog Devices, operating at a maximum clock frequency of 400 MHz. It features a dual-MAC architecture with two 16-bit multipliers and two 40-bit ALUs. The device includes 84 KB of on-chip L1 memory, configurable as instruction and data SRAM/cache, plus 4 KB of scratchpad SRAM. It operates at a core voltage of 1.2 V and supports I/O voltages of 1.8 V or 3.3 V. Packaged in a 176-lead LQFP, it integrates peripherals including two synchronous serial ports, a UART, SPI, three timers, and a parallel peripheral interface.

Digital Signal Processor Dsp Feature Summary

• Blackfin MSA architecture with dual 16-bit MACs and four 8-bit video ALUs for multimedia processing.
• 84 KB on-chip L1 memory configured as 48 KB instruction SRAM/cache, 32 KB data SRAM/cache, and 4 KB scratchpad SRAM.
• Integrated peripherals include two full-duplex SPORTs supporting eight stereo I2S channels, PPI, UART, SPI, and three 32-bit timers.
• Dynamic power management with programmable on-chip voltage regulator supporting operation down to 0.8 V.

Digital Signal Processor Dsp Applications

• Automotive digital audio broadcast (DAB) radio systems.
• MP3-compatible multi-way CD changers.
• Portable media player interfaces with dashboard display integration.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix SBSTZ400 against the manufacturer's current ordering guide to confirm package type, temperature range, and lead-free status. Confirm availability through authorized distributors as supply status may vary. Ensure design-in compliance with RoHS directives if required by the target application.

Digital Signal Processor Dsp Selection Notes

Select this model over the ADSP-BF531 or ADSP-BF533 based on the specific requirement for 84 KB of on-chip memory. The BF532 offers a balance between the lower memory capacity of the BF531 and the higher performance of the BF533. Ensure the system design accommodates the 176-lead LQFP footprint and thermal requirements for the -40°C to +85°C industrial temperature range.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-BF531/ADSP-BF532/ADSP-BF533 family. These processors are pin-compatible and code-compatible, differing primarily in on-chip memory size and maximum speed grades. The BF532 serves as a mid-range option within this series, providing enhanced memory resources compared to the BF531 while maintaining compatibility with the same development tools and software libraries.

Digital Signal Processor Dsp Replacement Considerations

Pin-compatible alternatives within the same family include the ADSP-BF531SBSTZ400 (lower memory) and ADSP-BF533SBSTZ400 (higher speed). Verify that the memory configuration differences do not impact existing firmware execution.
