LAN9646T-I/MXX is a six-port Gigabit Ethernet switch chip launched by Microchip, supporting multiple interfaces such as SGMII, RGMII, MII and RMII, and is suitable for the development of network devices. The following are its core features:

Structure of non-blocking wire-speed Ethernet switch

Full-featured forwarding and filtering control, including access control list (ACL) filtering

Ieee 802.1x support (Port-based Network Access Control)

IEEE802.1Q VLAN support is available, allowing for the establishment of 128 active VLAN groups and 4096 VLAN ids across the entire range

Insert or remove IEEE802.1p/Q tags based on each port, supporting dual tags

Tag/untag options based on the VLAN ID of each port

Ieee 802.3x full-duplex flow control and half-duplex back pressure collision control

IGMPv1/v2/v3 snooping is used for multicast packet filtering

IPv6 Multicast Listener Discovery (MLD) snooping

QoS/CoS packet priority support: 802.1p based on DiffServ, and 802.1p per-port priority remapping based on four priorities

IPv4/IPv6 QoS support

Programmable rate limiting for entry and exit ports

Broadcast storm protection

Four priority queues with dynamic packet mapping for IEEE802.1p, IPv4 DIFFSERV, and IPv6 TrafficClass

The MAC filtering function can filter or forward unknown unicast, multicast and VLAN data packets

Self-addressing filtering for implementing ring topologies

The high-speed SPI (4-wire, up to 50MHz) interface enables access to all internal registers

The I2C interface enables access to all registers

The MII management (MIM, MDC/MDIO 2-line) interface is used to access all PHY registers in accordance with the IEEE 802.3 specification

In-band management, access all registers through any one of the seven ports, in-band management

The I/O pin connection facility can set certain register bits from the I/O pins at reset time

The control register can be dynamically configured

Port mirroring/monitoring/sniffing: Traffic entering and leaving any port or MII/RMII

MIB counters that collect statistical information strictly in accordance with standards (34 MIB counters per port)

The entire chip software has lost power

Energy Detection Power Failure (EDPD

Local Area Network Wake-up (WoL) support

For details

The LAN9646T-I/MXX six-port Gigabit Ethernet switch is a fully integrated managed Layer 2, six-port Gigabit Ethernet switch with advanced features. The LAN9646T-I/MXX features four ports supporting 10/100/1000Mbps PHyS, and the other two can be configured as SGMII, RGMII, MII or RMII interfaces to connect to the host processor or external PHY. The LAN9646T-I/MXX can fully access registers via SPI, I2C or optional in-band management (via any data port), and the MIM interface provides access to PHY registers.

The security features of LAN9646T-I/MXX include authentication based on IEEE 802.1X port and ACL filtering. It also supports power management functions such as Energy Saving Ethernet (EEE) to achieve an energy-saving environment.
