ADSP-BF701KBCZ-1

Digital Signal Processor Dsp Overview

The ADSP-BF701KBCZ-1 is a Blackfin+ embedded processor from Analog Devices, operating at a maximum clock frequency of 200 MHz. It features a single core with 64 kB data RAM, 16 kB L1 instruction cache, and 32 kB L1 data cache. The device includes 128 kB of L2 SRAM and operates on a 1.1 V supply voltage. Packaged in an 88-lead LFCSP_VQ (QFN) format measuring 12 mm × 12 mm, it supports surface-mount installation. The component functions within a temperature range of 0°C to +70°C and integrates security accelerators alongside standard peripheral interfaces.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade and package variant against project requirements, as the ADSP-BF70x series offers multiple configurations. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure handling procedures account for moisture sensitivity classification during soldering processes to maintain device integrity.

Digital Signal Processor Dsp Selection Notes

Select this model when a 200 MHz processing speed is sufficient for the application's computational load. The 128 kB L2 SRAM configuration is suitable for designs that do not require external memory expansion. Consider the 88-lead QFN package for space-constrained PCB layouts compared to the larger BGA options available in the broader BF70x family.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-BF70x Blackfin+ processor family, which provides scalable performance up to 400 MHz across eight members. The BF701 specifically targets applications needing moderate processing power with integrated memory, distinguishing itself from higher-capacity variants like the BF707 while maintaining instruction set compatibility with previous Blackfin generations.

Digital Signal Processor Dsp Replacement Considerations

Direct functional substitutes within the same package include other ADSP-BF701 variants if different speed grades or memory sizes are acceptable. Cross-family replacements require careful evaluation of pin compatibility and software migration efforts due to architectural differences between Blackfin+ and other DSP cores.
