BCM43217KMLG

Overview

The BCM43217KMLG is a single-band RF transceiver manufactured by Broadcom Limited, belonging to the BCM4 series. It is designed as an ultimate low-cost solution for 2x2 MIMO 802.11n wireless applications. The component integrates radio frequency transmission and reception capabilities within a compact package suitable for embedded systems. Key specifications include compliance with RoHS3 standards and a Moisture Sensitivity Level (MSL) of 3, allowing for 168 hours of floor life at 30°C/60% relative humidity. The device is classified under Wireless & RF Integrated Circuits and supports standard industrial operating conditions.

Feature Summary

• Supports 2x2 MIMO architecture for enhanced 802.11n throughput
• Optimized for single-band 2.4 GHz operation
• Integrated RF transceiver design reduces external component count

Applications

• Single-band 802.11n wireless access points
• Embedded Wi-Fi modules for IoT devices
• Wireless network interface cards

Procurement Notes

Verify the specific ordering suffix and manufacturing date code upon purchase to ensure compatibility with current supply chain requirements. Confirm RoHS3 compliance status directly with the distributor or manufacturer representative, as regulatory documentation may be updated. Ensure that storage and handling procedures adhere to the specified MSL 3 guidelines to prevent moisture-induced damage during assembly processes.

Selection Notes

Select this component when a cost-effective, single-band 2x2 MIMO solution is required for 802.11n implementations. Compare against dual-band variants if 5 GHz support is unnecessary. Verify that the host system's antenna configuration matches the 2x2 MIMO requirements. Check for alternative packages within the BCM43217 family if different thermal or pinout constraints exist in the target design.

Part Context

This part belongs to the Broadcom BCM43217 family of wireless connectivity chips. It serves as a foundational component for legacy and budget-conscious 802.11n designs. The KMLG suffix typically denotes a specific lead-free tape and reel packaging option intended for automated surface-mount assembly processes.
