ADSP-BF544BBCZ-5A

Digital Signal Processor Dsp Overview

The ADSP-BF544BBCZ-5A is a Blackfin embedded processor from Analog Devices, operating at a maximum core instruction rate of 533 MHz. It features a dual-MAC signal processing engine with two 16-bit multipliers and two 40-bit ALUs. The device includes up to 324 Kbytes of on-chip memory, comprising L1 instruction/data SRAM/cache, L2 SRAM, and boot ROM. Key peripherals include high-speed USB OTG, SD/SDIO, ATA/ATAPI-6, four SPORTs, three SPIs, four UARTs, two CAN 2.0B interfaces, and an EPPI supporting LCD connections. It utilizes a 400-ball CSP_BGA package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix '5A' against the manufacturer's current ordering guide to confirm pinout, temperature range, and RoHS compliance status. Ensure the 400-ball BGA package dimensions match the target PCB footprint. Confirm availability through authorized distributors as supply levels may vary.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring 533 MHz performance with extensive peripheral integration including USB OTG and ATA/ATAPI. Compare against ADSP-BF542/BF547/BF548/BF549 for differences in L2 SRAM size (64 KB vs others), peripheral count (e.g., fewer SPORTs/SPIs than BF549), and clock speed variants.

Digital Signal Processor Dsp Part Context

Part of the ADSP-BF54x family, which shares code and pin compatibility. The BF544 variant specifically offers 533 MHz operation and 64 KB of L2 SRAM, distinguishing it from the higher-performance BF547/BF549 (600 MHz, 128 KB L2) and lower-memory BF542 (no L2).

Digital Signal Processor Dsp Replacement Considerations

Pin-compatible alternatives within the same family include ADSP-BF542BBCZ-5A, ADSP-BF547BBCZ-5A, ADSP-BF548BBCZ-5A, and ADSP-BF549BBCZ-5A. Verify memory capacity and peripheral availability requirements before substitution.
