Product Detail

Status: In Production
LAN9420/LAN9420i is a full-featured, Fast Ethernet controller which allows for the easy and cost-effective integration of Fast Ethernet into a PCI-based system. LAN9420/LAN9420i consists of a PCI Local Bus Specification Revision 3.0 compliant interface, DMA Controller, Ethernet MAC, and 10/100 Ethernet PHY. LAN9420/LAN9420i provides full IEEE 802.3 compliance and all internal components support full/half-duplex 10BASE-T, 100BASE-TX, and manual full-duplex flow control. The descriptor based scatter-gather DMA supports usage of zero-copy drivers, effectively increasing throughput while decreasing Host load. The integrated IRQ deassertion timer allows a minimum IRQ deassertion time to be set, providing reduced Host load and greater control over service routines. Automatic 32-bit CRC generation/checking, automatic payload padding, and 2K jumbo packets (2048 byte) are supported.*The LANCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
