YINGHUA ADSP-21489BSWZ-4B DSP for signal processing

The YINGHUA ADSP-21489BSWZ-4B is a digital signal processor supplied in a 176-pin LQFP package. It targets engineers developing audio, communications or industrial control systems that demand deterministic processing. The device is new and ready for prototype or production builds. No other peripherals or memory are included with the IC itself.

Surface-mount LQFP-176 installation requires

Installation uses standard surface-mount reflow on a 176-pin LQFP footprint. The fine pitch demands accurate stencil alignment and a controlled thermal profile to prevent bridging or tombstoning. Verify the PCB land pattern matches the package outline before assembly. Incorrect orientation or insufficient solder paste are the most common assembly faults.

Questions about this item

How can I verify the ADSP-21489BSWZ-4B is operating correctly after soldering the 176-pin LQFP package?

Power the device and confirm the clock starts; then run a known DSP routine and check that the expected output signals appear on the I/O pins.

What ships with the ADSP-21489BSWZ-4B and what must I source separately?

The tray contains only the 21489 DSP in its 176-lead LQFP package; you must supply the PCB, decoupling capacitors, crystal or clock source, voltage regulators and any programming header.
