Microchip Technology, Inc. Ethernet Switch, 10/100Mbps, Lqfp-48; Data Rate Microchip KSZ8863RLLI-TR

The Ethernet Switch, part number 41AH8412, is a 10/100 Mbps managed switch featuring an integrated 3-port design with PHYs. It supports advanced switching features including IEEE 802.1q VLAN support for up to 16 groups, programmable rate limiting, and broadcast storm protection. The device is compliant with IEEE 802.3u standards and utilizes a non-blocking switch fabric for efficient packet delivery, with a 1k MAC address lookup table and store-and-forward architecture. This switch offers comprehensive configuration options through various interfaces, including Serial Management Interface (SMI), MII Management (MIIM), SPI, and I2C. It supports QoS/CoS packet prioritization and includes features such as IGMP snooping for multicast filtering and MAC filtering for unknown unicast packets. The device operates within an industrial temperature range of -40¬8C to +85¬8C and is available in a 48-pin LQFP lead-free package. Applications for this switch include VoIP phones, set-top boxes, automotive systems, industrial control, and broadband gateways. Its low power dissipation features and energy-detect mode make it suitable for energy-efficient designs.
