ADSP-BF533SBBCZ400

Digital Signal Processor Dsp Overview

The ADSP-BF533SBBCZ400 is a Blackfin embedded processor from Analog Devices, operating at a maximum clock frequency of 400 MHz. It features a dual-MAC 16-bit signal processing engine with two 40-bit ALUs and four 8-bit video ALUs. The device includes up to 148 KB of on-chip memory, comprising 64 KB of L1 instruction SRAM and 64 KB of L1 data SRAM, alongside a 4 KB scratchpad. It operates at a core voltage of 1.2 V and supports I/O voltages of 1.8 V or 3.3 V. The processor is housed in a 160-ball CSP_BGA package and functions within an industrial temperature range of -40°C to +85°C.

Digital Signal Processor Dsp Feature Summary

• Blackfin architecture with dual 16-bit MACs, two 40-bit ALUs, and SIMD multimedia capabilities.
• Integrated 148 KB on-chip memory configuration including 64 KB L1 instruction SRAM and 64 KB L1 data SRAM.
• Rich peripheral set including PPI for ITU-R 656 video, dual SPORTs for audio, DMA controllers, and UART/SPI interfaces.
• Dynamic power management with programmable on-chip voltage regulator supporting frequencies up to 600 MHz.

Digital Signal Processor Dsp Applications

• Video detection systems requiring image acquisition and processing.
• Interfacing with high-speed parallel ADCs for imaging and medical ultrasound.
• Digital communication and consumer multimedia applications.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (400) against design requirements, as the BF533 family supports up to 600 MHz. Confirm package compatibility for the 160-ball CSP_BGA form factor. Check for moisture sensitivity levels and reflow soldering profiles appropriate for the surface-mount installation. Ensure supply chain sources provide genuine Analog Devices components to avoid counterfeit risks.

Digital Signal Processor Dsp Selection Notes

Select this model when a 400 MHz performance grade is sufficient, distinguishing it from the 600 MHz variants like the ADSP-BF533SKBCZ-6V. The 160-ball CSP_BGA package offers a compact footprint compared to the 169-ball PBGA or 176-lead LQFP options. Consider the 148 KB memory allocation if larger on-chip storage is needed, noting that lower-tier models like the BF531 have reduced memory capacities.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-BF531/ADSP-BF532/ADSP-BF533 series, which are pin-compatible and code-compatible. They share the same Blackfin architecture but differ in maximum clock speed and on-chip memory size. The BF533 represents the highest performance tier in this specific legacy group, offering up to 1200 MMACs at higher speeds.

Digital Signal Processor Dsp Replacement Considerations

Pin-compatible alternatives within the same family include the ADSP-BF531 and ADSP-BF532, though they offer lower memory and potentially lower speed grades. Higher speed versions such as the ADSP-BF533SKBCZ-6V (600 MHz) are functionally compatible but require verification of thermal and power constraints.
