Microchip 64-Pin Ethernet Controller, 3.3 V, 100 Mbps SPI Interface, Full Duplex/Half Duplex LAN9252/PT

Microchip LAN9252/PT is a high-integration 64-pin Ethernet controller designed for industrial and embedded applications requiring full duplex and half duplex communication at 100 Mbps speed via SPI interface. This controller includes dual integrated Ethernet PHYs featuring HP Auto-MDIX, enabling the use of direct connect or cross-over LAN cables, which simplifies network setup and reduces installation errors.

Operating at a supply voltage range strictly at 3.3 V, the device integrates an internal 1.2 V core regulator enabling single 3.3 V operation, ensuring efficient power management in constrained environments. The LAN9252/PT complies with the IEEE 802.3u standard to support reliable and standardized Ethernet communications.

The compact 64-pin package measures 10 mm length, 10 mm width, and 1.2 mm height, making it suitable for applications with strict PCB space limitations. The device incorporates internal loopback capabilities for ease of diagnostics and testing during development and deployment phases.

This Ethernet controller supports 2 transceivers, and with cable diagnostic support, it ensures network integrity and troubleshooting facilitation. While the integrated PHYs handle 100BASE-TX connections internally, 100BASE-FX fiber optic communications are supported through an external transceiver, expanding networking flexibility in industrial systems.

Dual integrated Ethernet PHYs with HP Auto-MDIX enable flexible cable use and network connections. Supports internal loopback mode for thorough system diagnostics and testing. Wide operating temperature range from 0°C to 70°C suitable for many industrial environments.

Small form factor 64-pin package designed for compact system integration. Conforms to IEEE 802.3u standards ensuring network compatibility and reliability. Ideal for developing cost-effective EtherCAT device solutions in industrial automation.

This controller is widely applicable in industrial automation, embedded control systems, manufacturing equipment, and any system requiring stable and fast Ethernet communication. Its compact package and low power operation make it a preferred choice for designers aiming to maximize performance while minimizing footprint.
