88E6131-B2-LAR1I000

The 88E6131-B2-LAR1I000 is a Marvell (now NXP) 8-port Gigabit Ethernet switch controller designed for low-power, cost-sensitive networking applications. It integrates an 8-port 10/100/1000 Mbps switch with advanced QoS, VLAN, and security features, making it suitable for SMB switches, IPTV, and industrial networking.
Key features:
- 8x Gigabit Ethernet ports (5x copper, 3x SerDes for fiber/uplinks).
- Layer 2 switching with 802.1Q VLAN and 802.1p QoS.
- Low power consumption (~1.5W typical).
- SPI or I2C management interface.
- Hardware-based security (ACL, storm control).
Applications include small office switches, embedded systems, and smart home gateways. The B2-LAR1I000 variant typically refers to a specific package (LQFP) and industrial-grade temperature support.
For detailed specs, refer to the Marvell 88E6131 datasheet.
