LAN8740AI-EN Network Controllers by Microchip Technology
10/100 Base-T/TX Ethernet Transceiver with Power Saving Features and Cable Diagnostics
| Status: | Active |
|---|---|
| Series: | LAN8740A |
| RoHS: | Compliant |
Microchip's LAN8740A/LAN8740Ai are the latest generation of low-power, 10/100 Fast Ethernet PHYs featuring Energy Efficient Ethernet (IEEE 802.3az) and Wake-On-LAN functionality, which provide system sleep modes for improved power savings. The LAN8740A/LAN8740Ai feature deterministic loop back delay, assuring real-time system performance as well as cable diagnostics which reduce network installation costs. These devices are available in both commercial (0° to 70°C) and industrial (-40° to 85°C) temperature ranges. The LAN8740A/LAN8740Ai are well-suited for Consumer, Embedded and Industrial applications. Additionally, these devices support auto-negotiation, auto-polarity correction, HP Auto-MDIX† and are compliant with IEEE 802.3 and 802.3u standards. Microchip also offers its complimentary and confidential LANCheck® online design review services free of charge to customers who select our products for their application design-in.*
†HP Auto-MDIX eliminates the need for special "crossover" cables when connecting LAN devices together.
*The LANCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
