Microchip launcht PCIe 3.1 Ethernet Bridges mit LPSS für Enhanced Power Efficiency

Embedded und Automotive Designer haben nun neue, Power-effiziente Lösung von Microchip: LAN7430 und LAN7431 PCIe 3.1 Ethernet Bridges. Beide Devices integrieren Power, Clocks und Ethernet PHY (LAN7430) oder Reduced Gigabit Media-Independent Interface (LAN7431) für alternative PHYs und Switches – vereinfachen Board Design und reduzieren Component Count.

LPSS Power Savings

Key zu Power Savings: Low-Power Sub-State (LPSS) L1.1 „Snooze“ und L1.2 „Off“ Modes – erlauben High-Speed PHY Circuitry Shutdown when Idle. Feature liefert messbare Battery Life Improvements für Portable und Automotive Systems.

Connectivity & Automotive Variant

Bei Host SoC/Processor Connection liefern Bridges 10/100/1000 Mbps Ethernet via PCIe 3.1 – bis 2,5 GT/s each Direction. LAN7431's RGMII Interface ermöglicht IEEE 802.3bw-2015 (100Base-T1) und IEEE 802.3bp-2016 (1000Base-T1) über Single Twisted Pair – Support Real-Time Ethernet, IEEE 1588-2008 (PTP), IEEE 802.1AS (gPTP) Precision Time Protocols. Automotive Variant LAN7431 exceeds AEC-Q100 Grade 2 Qualification.

Comprehensive Support Package

Microchip backed by Worldwide Technical Assistance, Design-Review Services, Fully Released Drivers für Linux und Windows. Customer-Driven Obsolescence Policy garantiert Continued Availability solange Demand exists.

True Single-Chip Solution: Beide operieren von Single 3,3 V Supply – eliminieren komplexe Power-Management-Circuitry. Inkl. JTAG (IEEE 1149.1) Test Access Port, LINK MD Diagnostics mit Time-Domain Reflectometry (TDR) für Cable Harness Issues (Opens, Shorts, Impedance Mismatches).

Free LANCheck Online Design Review, MPLAB® Connect Software für Easy OTP/Optional EEPROM Programming, WHQL-Certified Drivers, Linux Mainline Kernel Drivers für Networking und PTP/gPTP Sync. Evaluation Boards (EVB-LAN7430, EVB-LAN7431) verfügbar für Accelerated Integration.
