BCM53242MKPBG

BCM53242MKPBG is a Broadcom Ethernet switch IC (SoC) in the BCM53242 family. It’s intended for OEM networking gear and provides Layer-2 switching with integrated PHYs and a scalable switch fabric, suitable for SMB/industrial switches, access points, and embedded routers.
Key points:
- Multi-port Ethernet switching with built-in PHYs
- Features such as VLANs, QoS, IGMP snooping, and basic ACLs
- Hardware forwarding for low latency; supports management interfaces (e.g., MDIO) and Broadcom SDK/firmware
Packaging:
- MKPBG denotes a specific RoHS-compliant BGA package variant used in production
Note:
- Exact port counts, speeds (e.g., 10/100/1000), memory, power, and feature details vary by variant. For precise specs, consult the BCM53242 datasheet/product brief for the MKPBG package.

Here are the key features of BCM53242MKPBG (Broadcom switch chip):
- 24-port Ethernet switch (10/100/1000BASE-T) with high-speed hardware forwarding
- Layer 2/Layer 3 capabilities (IPv4/v6, static routing)
- Hardware MAC table (typical 8K entries) with fast forwarding
- VLAN support (802.1Q) with extensive VLAN features
- QoS: multiple queues, traffic policing/shaping, per-port and policy-based handling
- ACLs: hardware-based L2/L3/L4 access control
- Multicast: IGMP/MLD snooping and multicast routing support
- Spanning Tree Protocols: STP, RSTP, MSTP
- Link aggregation (802.3ad/LACP) and up/link trunking
- Jumbo frames support (up to ~9K)
- Management and discovery: LLDP, SNMP, CLI/management interfaces
- Security and reliability features (port security, rate limiting)
- Power efficiency features (EEE) and robust thermal/operational ranges
- Package: MKPBG (Broadcom BGA-style package) suitable for embedded/industrial applications
Note: exact port uplink counts and some capabilities may vary by SKU; refer to the datasheet for precise specs.

BGA — it uses a Ball Grid Array package.
