Package and Ordering Notes

The listed package is 32-lead QFN with 32 pins, leads, lands or contacts. The featured image is a generic package illustration for form-factor identification and is not an actual date-code or lot photograph. Lifecycle is recorded as Obsolete; confirm current factory support and last-time-buy constraints before design-in.

Sourcing Guidance

BCM5241A1KMLG is a legacy or obsolete orderable code. Source only with date-code, label, package and traceability checks appropriate to the application.

For an accurate quotation, include the full MPN, target quantity, acceptable date-code range, packaging format and destination. Icearth can help review traceability documents, label photos and electrical/package alignment before order placement.

Manufacturer Documentation

Technical values were checked against Broadcom documentation. Use the linked datasheet as the controlling source and re-check revisions before PCB release or firmware qualification.
