Product Overview
The MT7531AE/PCB is a low-power 7-port Gigabit Ethernet switch IC from MediaTek, built for low-latency high-throughput consumer routers, mesh APs, home gateways and small edge switches. It integrates five 10/100/1000Base-T copper PHYs plus two configurable GMAC uplink ports, supporting RGMII, SGMII or 2.5G HSGMII to pair with Wi-Fi 6/6E/7 or main network SoCs. Its non-blocking L2 switch fabric delivers full wire-speed forwarding on all ports. Built-in hardware QoS, VLAN management and IEEE 802.3az EEE power saving make it a stable, cost-effective solution for residential and small commercial high-bandwidth networking.
Core Advantages
Ultra-High Density Integration
Integrates 5 Gigabit copper PHYs, full L2 switching table and dual uplink GMACs on single chip, cuts external component count and assembly cost.
2.5G HSGMII High-Speed Uplink
HSGMII interface supports up to 2.5Gbps uplink bandwidth, eliminating throughput bottlenecks between switch and main processor without speed throttling.
Hardware QoS & Intelligent Traffic Scheduling
Supports strict priority queues, WRR scheduling and port rate limiting, prioritizing low-latency traffic including VoIP, 4K streaming and online gaming.
IEEE 802.3az Energy Efficient Ethernet
Dynamic low-power idle mode adjusts PHY power consumption based on link activity and cable length, reducing overall system heat and power draw.

Frequently Asked Questions
Q1: Is your currently available stock of the MT7531AE/PCB controller 100% genuine and original?
A: Yes, we guarantee that all MT7531AE/PCB integrated circuits in our inventory are 100% brand-new, factory-original products directly from MediaTek. Every product batch is logged and dispatched within standard anti-static ESD shielding pipelines under strict climate-regulated conditions.
Q2: What is the exact hardware meaning indicated by the “/PCB” extension on this ordering code?
A: The “/PCB” suffix stands for MediaTek’s specific substrate packaging revision, defining lead-free RoHS compliant pad layout parameters for standard SMT mass production assembly lines.
Q3: Can the MT7531AE handle 2.5Gbps WAN connections directly through its copper ports?
A: The five integrated copper transceivers natively support speeds up to 10/100/1000Mbps (Gigabit Ethernet). To achieve a 2.5Gbps external WAN port connection, one of the extension GMAC digital ports must be configured in HSGMII mode (2.5Gbps) and interfaced on the board with an external 2.5G copper PHY or an optical SFP transceiver module.
Q4: How can our technical division request reference schematics, SDK initialization drivers, or high-volume wholesale pricing schedules?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
