Product Description

Microchip LAN9252I/PT is a 64-pin Thin Quad Flat Package (TQFP) Ethernet Controller operating at 3.3 V and supporting a maximum data rate of 100 Mbps. It is designed with full duplex and half duplex communication modes suitable for industrial and embedded networking applications.

This device serves as a 2/3 port EtherCAT® slave controller, integrating dual Ethernet PHYs equipped with HP Auto MDI-X for flexible cable connections. The controller supports Ethernet standards IEEE 802.3, ANSI X3.263, and IEEE 802.3u, ensuring compatibility across various network environments.

The LAN9252 features a comprehensive data management system including 4K bytes dual port RAM (DPRAM), 4 SyncManagers, and 3 Fieldbus Memory Management Units (FMMUs) alongside a 64-bit Distributed Clock for accurate timing and synchronization.

Its integrated 1.2V regulator allows single 3.3V operation while supporting I/O voltage variations from 1.8V to 3.3V, making it suitable for diverse embedded system requirements. Surface mounting capability with a compact 10mm x 10mm footprint enhances PCB design flexibility.

Operational temperature range from -40°C to 85°C ensures reliable performance in harsh environments. Additional features include cable diagnostic support and 100BASE-FX compatibility via an external fiber transceiver.

The Microchip LAN9252I/PT is ideal for industrial automation, manufacturing communication systems, and embedded network controller applications requiring robust and high-speed Ethernet interfaces.

This controller integrates a 2/3-port EtherCAT® slave controller with 3 Fieldbus Memory Management Units (FMMUs) and 4 SyncManagers. Dual integrated Ethernet PHYs with HP Auto-MDIX support improve network cable compatibility.

Cable diagnostic support aids in network maintenance and troubleshooting. Supports 100BASE-FX network via an external transceiver for fiber optic connectivity. Operates on a 3.3V supply with integrated 1.2V regulator for efficient power management.

Compact 64-pin TQFP surface mount package measuring 10mm by 10mm by 1.2mm. Wide operating temperature range from -40°C to 85°C enhances durability in industrial settings.
