Procurement Notes

Verify the specific suffix '402' against official Analog Devices documentation to confirm the exact speed grade and package variant. Confirm availability status through authorized distributors, as lead times may vary. Ensure compliance with RoHS directives and check humidity sensitivity handling requirements during storage and assembly.

Selection Notes

Select this component when a 400 MHz Blackfin core is required with the specified memory configuration. Verify that the LQFP-176 footprint fits the PCB layout constraints. Ensure the power supply design accommodates the 1.1 V to 1.47 V core voltage and supports the necessary I/O voltage levels for system connectivity.

Part Context

This part belongs to the ADSP-BF518 series of Blackfin processors. The 'WBSWZ' designation typically indicates a wide temperature range (industrial) and lead-free packaging compliant with environmental standards. The suffix '402' specifies the performance grade corresponding to the 400 MHz operating frequency.

Replacement Considerations

Direct replacements include other members of the ADSP-BF518 family with compatible pinouts and memory sizes. Cross-referencing with the ADSP-BF512 or ADSP-BF519 series may be possible if software compatibility and peripheral requirements allow, provided the package and speed grades match.
