AN983BX-BG-T-V3

Overview

The AN983BX-BG-T-V3 is a network controller and processor IC manufactured by Infineon Technologies. It functions as an Ethernet controller compliant with IEEE 802.3 standards, supporting 10/100 Base-T/TX PHY operations. The device integrates a PCI interface for system connectivity and is housed in a 128-BFQFP (PG-PQFP-128) package. It operates within a supply voltage range of 3V to 3.6V and draws a maximum supply current of 150mA. The component is rated for an operating temperature range of 0°C to 70°C and holds a Moisture Sensitivity Level (MSL) of 3, corresponding to 168 hours. This specific part number is currently listed as obsolete or discontinued.

Procurement Notes

This component is officially classified as obsolete or discontinued by the manufacturer. Availability is restricted to existing stock or secondary market sources. Verification of authenticity and physical condition is critical when sourcing from non-direct channels. Designers should consider this status for long-term production planning and ensure compatibility with replacement strategies if necessary.

Selection Notes

Engineers selecting this part must verify PCI bus compatibility and 3.3V power requirements. The 128-pin BFQFP package demands appropriate PCB footprint design and reflow soldering profiles suitable for fine-pitch QFP components. Due to its discontinued status, alternative components with equivalent PCI-to-Ethernet bridge capabilities should be evaluated for new designs to ensure supply chain stability.

Part Context

The AN983 series represents Infineon's legacy portfolio of network controllers designed for bridging PCI buses to Ethernet media. The BX variant specifically targets 10/100 Mbps applications. This family was widely used before the prevalence of native PCIe and integrated SoC networking solutions. The V3 suffix typically denotes a specific manufacturing revision or tape-and-reel configuration within the broader AN983 product line.

Replacement Considerations

Direct pin-to-pin replacements are not publicly confirmed for this obsolete part. Engineers should evaluate modern PCI-to-Ethernet bridge chips or USB-to-Ethernet adapters depending on system constraints. Consulting Infineon's official obsolescence notices is recommended for approved transition paths.
