ADSP-BF533SBBC400

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 L1 instruction and data SRAM/cache and a 4 KB scratchpad. It operates at a core voltage of 1.2 V and supports dynamic power management via an on-chip programmable voltage regulator. The processor integrates peripherals such as PPI, SPORTs, DMA controllers, timers, UART, and SPI, housed in a 160-ball CSP_BGA package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'Z400' against official Analog Devices documentation to confirm the 400 MHz speed grade and RoHS compliance status. Ensure the ordering part number matches the exact package type (CSP_BGA) required for the design. Cross-reference the datasheet revision history for any updates to electrical characteristics or thermal parameters before finalizing procurement specifications.

Digital Signal Processor Dsp Selection Notes

Select this model when a 400 MHz performance level is sufficient for the application, distinguishing it from the 600 MHz ADSP-BF533SKBCZ variants. Consider the 148 KB on-chip memory capacity for code and data storage requirements. Verify that the 160-ball CSP_BGA package fits the PCB layout constraints compared to the 169-ball PBGA or 176-lead LQFP options available for the BF533 family.

Digital Signal Processor Dsp Part Context

The ADSP-BF533SBBCZ400 belongs to the ADSP-BF531/ADSP-BF532/ADSP-BF533 series, which are pin-compatible and code-compatible. These processors share the same Blackfin architecture but differ in on-chip memory size and maximum clock speed. This specific part represents the highest memory configuration within the 400 MHz speed bin of the initial Blackfin generation.

Digital Signal Processor Dsp Replacement Considerations

Pin-compatible replacements within the same family include the ADSP-BF531 and ADSP-BF532, though they offer lower memory capacities. Higher performance alternatives in the same package include the ADSP-BF533SKBCZ series operating at 600 MHz. Ensure software compatibility when migrating between these variants due to potential differences in available on-chip resources.
