ADM8513X-AD-T-1

Overview

The ADM8513X-AD-T-1 is a USB-to-Ethernet LAN controller integrating a full-speed USB device interface and a 10/100 Mbps Ethernet MAC/PHY. It complies with IEEE 802.3/802.3u standards and USB 1.0/1.1 specifications. The device features an internal 2K-byte two-port asynchronous SRAM for FIFO operations, supporting four endpoints: one control endpoint (max 8-byte packet), one bulk IN endpoint (max 64-byte packet), one bulk OUT endpoint (max 64-byte packet), and one interrupt IN endpoint (max 8-byte packet). It operates on a 3.3 V power supply with 5 V I/O tolerance and includes an EEPROM interface for configuration storage.

Feature Summary

• Integrates a 10/100 Mbps Ethernet PHY compliant with IEEE 802.3/802.3u standards, including auto-negotiation and flow control support.
• Functions as a full-speed USB device with dedicated endpoints for bulk data transfer and interrupt status reporting.
• Includes an internal 2K-byte synchronous SRAM acting as a dual-port FIFO for efficient packet buffering.
• Supports external EEPROM access to automatically load device and vendor IDs upon power-on reset.

Applications

• USB-based network adapters for desktop and laptop computers
• Embedded systems requiring Ethernet connectivity via USB host interfaces
• Industrial controllers utilizing USB for peripheral communication

Procurement Notes

Verify the component against the official Infineon Technologies datasheet Rev. 1.21 dated December 2005. Confirm that the ordering suffix matches the specific package variant required. Ensure compatibility with legacy operating system drivers such as Win98, ME, 2000, XP, Linux, and WinCE. Cross-reference pin assignments and electrical characteristics with the provided documentation before integration.

Selection Notes

Select this controller for applications requiring a standalone USB-to-Ethernet bridge without external PHY components. Consider the 48-pin LQFP package constraints and the requirement for an external crystal oscillator for the 48 MHz USB clock and 25 MHz Ethernet clock. Evaluate the need for external EEPROM storage if persistent MAC address configuration is required across power cycles.

Part Context

This component belongs to the ADM8513 family of USB-to-Ethernet controllers manufactured by Infineon Technologies. It serves as a bridge between USB host controllers and Ethernet networks, consolidating MAC and PHY functions into a single integrated circuit. The device supports standard USB enumeration procedures and provides GPIO pins for additional system control or status indication.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the verified source material. Designers should consult Infineon Technologies for current product line replacements or equivalent solutions from other manufacturers, ensuring functional compatibility with USB 1.1 and 10/100 Mbps Ethernet standards.

FAQ

What is the maximum packet size supported by the bulk endpoints?

The bulk IN and bulk OUT endpoints support a maximum packet size of 64 bytes.

How does the device handle Ethernet configuration after reset?

After a power-on reset, the MAC automatically loads the device ID and vendor ID from an external serial EEPROM connected via the EECS, EEDI, EEDO, and EESK pins.

Does the ADM8513X support auto-negotiation for link speed?

Yes, the integrated Ethernet PHY supports auto-negotiation for both 10BASE-T and 100BASE-TX connections.
