BCM5327MA1KQMG Description

Short technical summary and product information.

The BCM5327MA1KQMG is a highly integrated eight-port 10/100 Ethernet switch from Broadcom Limited, designed for low-cost managed and unmanaged switching applications. It combines eight 10BASE-T/100BASE-TX transceivers, nine media access controllers, and a 256 KB on-chip packet buffer into a single 208-pin PQFP package.

 

Key specifications include a non-blocking switch fabric, support for up to 4096 MAC addresses, port-based VLAN, and 802.1p QoS priority queues. Flow control is supported in both full-duplex (802.3x) and half-duplex modes. The device also features HP auto-MDI/MDIX for automatic cable detection and an internal oscillator circuit to simplify design.

 

Typical power consumption is less than 1.8 W, making it suitable for compact, energy-efficient switch designs. The BCM5327MA1KQMG supports an MII or 7-wire interface for an additional 100FX or 100TX connection, enabling uplink or fiber connectivity. Management features include hardware support for SNMP, RMON, and Spanning Tree, as well as a low-cost MIB Autocast function for statistics collection.
