Product details
Overview
AN983B-BG-T-V8 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 operation, 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 embedded industrial PCs and legacy Mini-PCI add-in cards for wired network connectivity.
For engineers reviewing the AN983B-BG-T-V8 datasheet, AN983B-BG-T-V8 pinout, AN983B-BG-T-V8 application, or AN983B-BG-T-V8 equivalent, key selection criteria include MII PHY interface compatibility, PCI revision 2.2 timing compliance, EEPROM-based configuration storage, Wake-on-LAN register control (CSR15/CSR18), and transceiver reset isolation capability.
Technical Context
The AN983B-BG-T-V8 implements a full-duplex 10/100BASE-TX MAC with integrated PCI bus master logic compliant with PCI Local Bus Specification Rev. 2.2. It uses descriptor ring or chain structures for DMA-managed frame buffers and supports both normal and early interrupt modes to reduce host CPU overhead during high-throughput traffic.
Its PHY interface operates in MII mode with configurable MDIO/MDC signaling (STA- or PHY-sourced), supports flow control via PAUSE frames, and includes hardware-accelerated CRC-32 generation/checking. Reset architecture separates chip-level and transceiver-only reset paths (CSR18[27] and CSR18[26]), enabling selective recovery without full reinitialization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 10/100 Mbps IEEE 802.3u-compliant full/half-duplex operation with auto-negotiation support. |
| Bus Interface | 32-bit, 33 MHz PCI Local Bus Rev. 2.2 compliant; supports memory-mapped I/O and bus mastering. |
| PHY Interface | MII (Media Independent Interface) with programmable MDIO direction and 25 MHz crystal accuracy requirement. |
| Power Management | ACPI D0–D3hot/D3cold states; Wake-on-LAN triggered by Magic Packet with pattern match in low-power D3 state. |
| Packet Buffering | Descriptor-based ring/chain DMA engine with configurable receive/transmit descriptor counts and early-interrupt thresholds. |
| Configuration Storage | External serial EEPROM (I²C-compatible) for MAC address, PHY settings, LED behavior, and vendor-specific parameters. |
| LED Control | Dual-mode LED driver supporting 3-LED (Link/Activity/Speed) or 4-LED (Link/Activity/Speed/Full-Duplex) configurations. |
Pinout & Package
AN983B-BG-T-V8 is housed in a 128-pin Plastic Quad Flat Package (PQFP) with 0.4 mm lead pitch and 20 mm × 20 mm body size. Thermal pad exposed on underside for enhanced heat dissipation in compact Mini-PCI form factor applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN | PCI Clock Input | Accepts 33 MHz PCI system clock; drives internal PLL for MAC and PHY timing domains. |
| MDIO / MDC | PHY Management Interface | Bidirectional MDIO and clocked MDC signals for reading/writing PHY registers (e.g., BMCR, BMSR). |
| TXD[3:0] / RXD[3:0] | MII Data Bus | 4-bit parallel transmit/receive data path between MAC and external PHY; synchronized to TX_CLK/RX_CLK. |
| LED0–LED3 | LED Output Drivers | Open-drain outputs supporting direct connection to LEDs with current-limiting resistors; configurable per mode. |
| RESET# | Active-Low Global Reset | Asynchronous reset asserting CR49[1:0] and clearing all internal registers except EEPROM shadow contents. |
| EEPROM_SCL / SDA | Serial EEPROM Interface | I²C-compatible clock/data lines for boot-time loading of MAC address and configuration parameters. |
Key Features
| Feature | Design Value |
|---|---|
| Wake-on-LAN with Magic Packet filtering | Hardware-accelerated pattern matching on incoming frames while in D3 state; no host CPU wake required until match occurs. |
| Transmit Early Interrupt | Generates interrupt after first descriptor completion-not full frame-reducing latency for small packets and improving real-time response. |
| Receive Early Interrupt | Triggers interrupt upon descriptor write completion before full frame reception, enabling zero-copy buffer pre-allocation in driver stack. |
| Isolated Transceiver Reset | CSR18[26]/CSR18[27] bits allow resetting only the PHY section without disturbing MAC or PCI interface state. |
| Flexible Descriptor Management | Supports both ring and chain descriptor structures with software-configurable head/tail pointers and status bit polling. |

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 | Single-chip 10/100 Mbps PCI controller with integrated PHY; lacks MII interface and Wake-on-LAN Magic Packet filtering. | Requires no external PHY but offers no PHY-level debug visibility or flexible media adaptation. | Choose when cost-sensitive designs prioritize integration over PHY configurability and WoL precision. |
| Intel 82559ER | PCI-based 10/100 Mbps controller with integrated PHY, advanced power management (AGP-style D1/D2), and TCO watchdog support. | Targeted at desktop/laptop platforms with Intel chipset ecosystems; requires different driver model and BIOS hooks. | Prefer when deploying into Intel-centric industrial motherboards with existing 82559 driver infrastructure. |
Compared with RTL8139D and 82559ER, the AN983B-BG-T-V8 uniquely provides MII separation for PHY vendor flexibility, hardware-accelerated WoL pattern matching independent of host state, and dual-mode LED control optimized for space-constrained Mini-PCI layouts.

FAQ
Does AN983B-BG-T-V8 support PCIe?
No. The AN983B-BG-T-V8 implements only the legacy PCI Local Bus Specification Rev. 2.2 (32-bit, 33 MHz). It lacks PCIe electrical signaling, enumeration protocol, or configuration space mapping. Migration to PCIe requires a discrete bridge IC or redesign with a native PCIe Ethernet controller.
Can it operate without an external EEPROM?
No. The AN983B-BG-T-V8 requires an external I²C-compatible serial EEPROM to store the MAC address, PHY configuration, LED mode settings, and vendor ID. Absence of EEPROM prevents successful initialization and results in undefined MAC behavior or link failure.
What is the function of CSR18[26] and CSR18[27]?
CSR18[26] (PMEP) enables Power Management Event generation on PCI PME# signal assertion. CSR18[27] (PMEPEN) enables the PME# output itself. Together they control Wake-on-LAN event signaling to the PCI host during D3 state, allowing the host to detect and respond to Magic Packet arrival.
Is the MII interface electrically compatible with standard PHYs like the DP83848?
Yes. The AN983B-BG-T-V8's MII signals (TXD[3:0], RXD[3:0], TX_EN, RX_DV, CRS, COL, TX_CLK, RX_CLK, MDIO, MDC) conform to IEEE 802.3u MII timing and voltage levels (3.3 V CMOS). It has been validated with TI DP83848, National DP83847, and similar MII-compliant PHYs in reference designs.
