Product details
Overview
AN983BX-BG-R-V1 from Infineon Technologies is a PCI/Mini-PCI-to-Ethernet LAN controller IC integrating MAC, PHY interface (MII), and PCI bus interface in a single PQFP-128 package. It supports 10/100 Mbps Ethernet, Wake-on-LAN via Magic Packet, ACPI power management (D0–D3 states), and on-chip descriptor-based packet buffering with early transmit/receive interrupt capability. Used in legacy industrial PC add-in cards and embedded Mini-PCI network modules.
For engineers reviewing the AN983BX-BG-R-V1 datasheet, AN983BX-BG-R-V1 pinout, AN983BX-BG-R-V1 application, or AN983BX-BG-R-V1 equivalent, key selection criteria include MII PHY compatibility, PCI revision 2.2 timing compliance, EEPROM-based configuration storage, LED control flexibility (3- or 4-LED modes), and transceiver reset isolation capability.
Technical Context
The AN983BX-BG-R-V1 implements a full-duplex 10/100 Mbps MAC layer compliant with IEEE 802.3u, coupled with MII interface logic for external PHY connection. Its PCI interface operates at 33 MHz with 32-bit data width and supports both memory-mapped and I/O-mapped access.
It features dual descriptor ring management (transmit and receive), programmable interrupt coalescing via early interrupt scheme, and hardware-accelerated flow control using PAUSE frames. The device includes integrated CSR registers for PHY control (via MDIO/MDC) and internal configuration registers mapped to PCI space.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Interface Standard | PCI Rev. 2.2 compliant, 32-bit/33 MHz, memory- and I/O-mapped |
| Ethernet Speed | 10/100 Mbps base-T, full/half-duplex operation supported |
| PHY Interface | MII (Media Independent Interface) with MDIO/MDC for external PHY control |
| Power Management | ACPI D0–D3 states; Wake-on-LAN via Magic Packet detection in D3hot |
| Packet Buffering | Descriptor-based ring or chain structure; configurable buffer size up to 16 KB |

Pinout & Package
PQFP-128 (Plastic Quad Flat Package, 20 mm × 20 mm, 0.4 mm pitch), RoHS-compliant green package per Rev. 1.81 (2005).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN | PCI Clock Input | Accepts 33 MHz ±0.5% crystal or clock source; drives internal PCI timing and MAC logic |
| MDIO / MDC | PHY Management Interface | Bi-directional MDIO and output MDC signals for reading/writing external PHY registers (e.g., DP83843) |
| TXD[3:0] / RXD[3:0] | MII Data Bus | 4-bit parallel transmit/receive data path between MAC and external PHY; synchronous to TX_CLK/RX_CLK |
| LED0–LED3 | LED Driver Outputs | Open-drain outputs supporting 3- or 4-LED configuration for link, activity, speed, and collision status |
| RESET# | Active-Low Global Reset | Asynchronous reset of entire chip; deassertion initiates PCI enumeration and internal initialization flow |
| WOL# | Wake-on-LAN Trigger Input | Active-low input detecting Magic Packet wake event during D3 state; triggers internal WOL logic and PCI wake signal |
Key Features
| Feature | Design Value |
|---|---|
| Descriptor-Based DMA Engine | Hardware-managed transmit/receive descriptor rings with head/tail pointer registers; eliminates CPU polling overhead |
| Early Interrupt Scheme | Reduces interrupt latency by triggering before full frame completion-enables low-latency real-time response |
| Isolated Transceiver Reset | Dedicated TRST# pin allows PHY reset without affecting MAC or PCI logic-critical for PHY recovery without system restart |
| Flexible LED Configuration | Software-selectable 3-LED (Link/Activity/Speed) or 4-LED (Link/Activity/Speed/Collision) mode via CSR register bit |
| EEPROM Auto-Load | On power-up, loads MAC address, subsystem IDs, and PHY init values from external serial EEPROM-no host firmware initialization required |
Applications
| Industrial PC Add-in Card | Mini-PCI Embedded Network Module |
|---|---|
|
Use Scenario: Retrofitting legacy industrial PCs with 10/100 Mbps Ethernet connectivity where PCIe is unavailable. IC Role / Device Role / Timing Role: PCI bus master providing MAC-layer framing, MII interface to external PHY, and PCI configuration space enumeration. Use Value: Enables drop-in replacement of obsolete NIC controllers without BIOS or driver modification-supports standard NDIS 5.x drivers. |
Use Scenario: Compact network interface in fanless embedded systems using Mini-PCI slot (e.g., POS terminals, kiosks). IC Role / Device Role / Timing Role: Integrated PCI-to-MII bridge with low-power D3 state entry and WOL wakeup capability. Use Value: Reduces BOM count by eliminating separate PCI bridge + MAC + PHY chips; supports remote maintenance via WOL. |
| Legacy Telecom Gateway | Network Appliance Control Plane |
|
Use Scenario: Control-plane Ethernet interface in TDM-to-IP gateways requiring deterministic packet handling. IC Role / Device Role / Timing Role: Deterministic descriptor ring management with early interrupt support for sub-100 µs latency-critical control packets. Use Value: Guarantees timely delivery of signaling packets (e.g., SIP, H.248) without jitter introduced by software polling. |
Use Scenario: Out-of-band management interface in firewalls or load balancers with dual-NIC architecture. IC Role / Device Role / Timing Role: Dedicated management NIC with isolated reset and EEPROM-stored MAC address-immune to main data-plane resets. Use Value: Ensures continuous remote access even during data-plane firmware updates or crashes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PCI-to-Ethernet controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Realtek RTL8139D | Integrated 10/100 PHY; no MII interface; uses internal PHY instead of external MII-connected PHY | Eliminates need for external PHY but lacks PHY vendor flexibility and diagnostic visibility via MII registers | Select when cost-sensitive designs prioritize integration over PHY customization or debug access |
| Intel 82559ER | PCI-X capable (66 MHz); supports advanced features like TCP/IP offload and VLAN tagging not present in AN983BX | Targeted at higher-performance desktop/server NICs-not pin- or register-compatible | Select when migrating to newer platforms requiring extended feature set and broader OS driver support |
Compared with RTL8139D and Intel 82559ER, the AN983BX-BG-R-V1 uniquely balances MII PHY flexibility, deterministic descriptor handling, and legacy PCI compatibility-making it optimal for long-lifecycle industrial Mini-PCI designs where PHY selection and interrupt latency matter more than PHY integration or offload features.

FAQ
Does AN983BX-BG-R-V1 include an integrated Ethernet PHY?
No. The AN983BX-BG-R-V1 implements only the MAC layer and PCI interface; it requires an external MII-compliant PHY (e.g., National Semiconductor DP83843 or Broadcom BCM5221) connected via the MII bus. This architecture enables PHY selection based on noise immunity, power, or diagnostic requirements.
What EEPROM protocols and capacities are supported?
The device supports standard I²C-compatible serial EEPROMs with 1 Kbit (128 × 8) capacity, accessed via dedicated EEPROM clock/data pins. It auto-reads MAC address, vendor ID, subsystem ID, and PHY initialization values at power-on-no host intervention required for basic operation.
How does Wake-on-LAN operate in D3 state?
In D3hot, the AN983BX-BG-R-V1 maintains minimal power to its WOL detection circuitry. Upon receiving a valid 6-byte preamble followed by 16 repetitions of the target MAC address (Magic Packet), it asserts the PCI_WAKE# signal and transitions to D0, enabling full system resume through BIOS/OS power management firmware.
Is the AN983BX-BG-R-V1 compatible with modern operating systems?
Yes-standard NDIS 5.x drivers exist for Windows 2000/XP/Server 2003, and Linux kernel modules (e.g., 8139too-derived patches) support it via PCI ID 1114:983B. Driver availability depends on legacy OS support; no native Windows 10/11 or recent Linux mainline support exists.
