Overview

Description

BCM5221A4KMLG is a Broadcom Gigabit Ethernet controller (NIC) with an integrated MAC and PHY. It provides 10/100/1000 Mbps Ethernet and connects to a host via PCI Express (PCIe), while interfacing to the Ethernet magnetics (RJ-45) through its PHY. The A4KMLG suffix identifies a specific RoHS-compliant packaging/revision used in OEM NICs and embedded boards.
Uses:
- Acts as the NIC in PCs, servers, or embedded systems.
- Requires Broadcom drivers on Windows or Linux (appears as bcm5221 or similar).
What you’ll need:
- The correct driver package from Broadcom or your OS vendor.
- The appropriate PCIe slot and power/signal integrity for the board.
For precise electrical specs, timing, and supported features (offloads, VLAN, etc.), consult the Broadcom BCM5221 datasheet and the packaging documentation for the A4KMLG variant. If you share your OS and platform, I can outline specific driver steps.

Package

BCM5221A4KMLG uses a QFN package, 64-pin (QFN-64), RoHS-compliant.

Pinout

BCM5221A4KMLG is a Broadcom Gigabit Ethernet PHY in a 48-pin package (LQFP). Function: a 10/100/1000BASE-T Ethernet PHY (transceiver) with MDI to magnetics and MAC interface (MII/GMII or RMII) plus MDIO/MDC management and LED outputs.

Manufacturer
