ADM5120X-AB-T-2-G

Overview

The ADM5120 is a System-On-Chip network controller integrating a 4Kc MIPS CPU, embedded switch engine, five-port 10/100M PHY, and USB host. The processor operates at 175 MHz delivering 227 MIPS with an MMU and 8KB I/D caches. It features IEEE 802.3 Fast Ethernet interfaces with auto-MDIX, PCI, UART, SDRAM, and Flash connections. Built on 0.18µm CSM CMOS technology, the device supports variable voltage operation between 1.8V and 3.3V within a 324-ball BGA package.

Feature Summary

Procurement Notes

Verify component authenticity through authorized Infineon distribution channels. Confirm package integrity for the 324-ball BGA configuration prior to installation. Ensure compatibility with required 1.8V and 3.3V power rails during system design validation.

Selection Notes

Select this SoC for applications requiring integrated routing, switching, and USB hosting capabilities. Evaluate memory requirements against the embedded SSRAM and external SDRAM/Flash interfaces. Consider the 175 MHz processing speed for handling NAT and firewall tasks in small office environments.

Part Context

The ADM5120 belongs to Infineon's wireline communications portfolio, specifically designed as a network controller. It combines processing, switching, and physical layer functions into a single chip to reduce bill-of-materials complexity for broadband access devices.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify functional equivalence if considering alternative vendors for MIPS-based networking SoCs.
