Product details
Overview
DP83815DUJB/NOPB from Texas Instruments (formerly National Semiconductor) is a single-chip 10/100 Mb/s PCI Ethernet MAC and integrated physical layer (PHY), implementing IEEE 802.3/802.3u standards with full-duplex support, 2 KB Tx/Rx FIFOs, and Wake-on-LAN capability for embedded PC motherboards and adapter cards.
For engineers reviewing the DP83815DUJB/NOPB datasheet, DP83815DUJB/NOPB pinout, DP83815DUJB/NOPB application, or DP83815DUJB/NOPB equivalent, key selection criteria include PCI V2.2 compliance, integrated 3.3V PHY with auto-negotiation, MII interface for external PHY extension, low-power WOL mode (380 mW), and LBGA-160 package compatibility with legacy PC designs.
Technical Context
The DP83815DUJB/NOPB integrates a PCI MAC/BIU compliant with PC 97/98/99 and ACPI v1.0, supporting bus-mastering transfers up to 128 dwords (512 bytes) and power management states D0–D3cold. Its internal PHY implements ANSI X3.263-compliant TP-PMD with adaptive equalization and baseline wander compensation for 100BASE-TX.
It supports IEEE 802.3x flow control, VLAN tagging, deep packet pattern matching (4 unique patterns), and RFC 1213/RFC 1398 MIB-II statistics collection. The device uses a single 25 MHz reference clock and provides configurable EEPROM auto-load for boot configuration and remote boot via Flash/PROM interface.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 10/100 Mb/s full/half-duplex operation per IEEE 802.3u; enables cost-effective migration from 10BASE-T to Fast Ethernet without external PHY. |
| PCI Interface | V2.2 33 MHz bus master; reduces host CPU overhead via descriptor-based DMA and burst transfers up to 512 bytes. |
| Integrated PHY | 3.3V CMOS 10BASE-T + 100BASE-TX transceiver with auto-negotiation, TP-PMD compliance, and adaptive signal conditioning. |
| Power Modes | D0–D3cold support; WOL mode draws 380 mW, sleep mode 33 mW - critical for energy-sensitive embedded systems. |
| FIFO Size | 2 KB transmit + 2 KB receive buffers; absorbs packet bursts and decouples MAC/PHY timing mismatches. |
| Management Interface | MII (MDIO/MDC) with register access to internal PHY; allows software control of link status, speed, duplex, and diagnostics. |
| Wake Events | Supports Magic Packet™, directed packets, ARP, VLAN, pattern match, and PHY status change - meets PC98/PC99 OnNow requirements. |
Pinout & Package
The DP83815DUJB/NOPB is packaged in a 160-pin LBGA (UJB160A), optimized for high-density PCB layouts and thermal performance in space-constrained embedded applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AD[31:0] | PCI Address/Data Bus | Multiplexed 32-bit address/data lines; enables direct memory-mapped I/O and bus-mastering DMA transfers. |
| CBEN[3:0] | PCI Command/Byte Enable | Defines transaction type during address phase; selects active byte lanes (0–3) during data phase in Little Endian mode. |
| PCICLK | PCI System Clock | 33 MHz input clock; rising edge synchronizes all PCI bus phases - requires stable, low-jitter source. |
| INTA# | PCI Interrupt Request | Active-low shared interrupt output; asserts on status events (e.g., Rx complete, Tx error, WOL trigger). |
| MDC / MDIO | MII Management Interface | 2.5 MHz serial clock and bidirectional data bus for reading/writing internal PHY registers (e.g., BMSR, ANAR). |
| RXCLK / RXD[3:0] / RXDV / RXER | MII Receive Interface | Recovery-clock-synchronous nibble-aligned data path; used only when CFG:EXT_PHY = 1 - otherwise internal PHY drives MAC directly. |
| TXCLK / TXD[3:0] / TXEN / CRS / COL | MII Transmit Interface | Drives external PMD; TXEN enables transmission, CRS indicates carrier presence, COL signals collision detection. |
| PMEN#/CLKRUN# | Power Management Event/Clock Run | Dual-function pin: signals WOL events or controls dynamic clock gating to reduce idle power in mobile designs. |
Key Features
| Feature | Design Value |
|---|---|
| IEEE 802.3/802.3u Compliance | Fully implements MAC and PHY layers for interoperable 10/100BASE-T operation - eliminates need for discrete PHY ICs. |
| Flexible Packet Filtering | Single-address perfect filter + 512-entry multicast/unicast hash table + 4-pattern deep packet match - enables precise traffic steering in firewall or IDS applications. |
| On-chip Statistics Engine | Gathers RFC 1213 MIB-II and IEEE 802.3 LME counters (e.g., Rx/Tx octets, collisions, errors); offloads SNMP agent processing from host CPU. |
| EEPROM Auto-Load | Loads configuration (MAC address, PHY settings, WOL filters) at power-on from external 93C46-compatible serial EEPROM - simplifies board bring-up and field updates. |
| Flash/PROM Boot Support | Direct interface to BIOS ROM or network boot PROM - enables PXE boot and remote firmware recovery in headless systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet MAC+PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RTL8139D-GR | PCI 10/100 MAC+PHY with 8 KB Tx/Rx buffer; lacks MII interface and advanced WOL packet filtering. | Targeted at consumer PC add-in cards; no RFC 1213 MIB support or VLAN acceleration. | Choose for lowest-cost implementation where deep packet inspection and standards-compliant management are not required. |
| KSZ8041NL | Standalone 10/100 PHY only (no MAC); requires external MAC (e.g., SoC Ethernet controller); supports RGMII/MII. | Used in ARM-based embedded systems with integrated MAC; enables PHY-level customization and lower power in active mode (120 mW). | Choose when system architecture mandates separation of MAC and PHY or demands modern low-power PHY features like EEE. |
Compared with RTL8139D-GR, DP83815DUJB/NOPB offers superior standards compliance (PC99/ACPI), richer WOL event support, and integrated MIB counters - making it preferable for certified commercial platforms.

The DP83815DUJB/NOPB serves as a fully integrated 10/100 Mb/s PCI Ethernet controller combining MAC and PHY functions. It handles frame assembly/disassembly, CRC calculation, auto-negotiation, physical signaling over twisted-pair media, and bus-mastering DMA transfers - eliminating the need for separate MAC and PHY ICs in legacy PC and embedded designs.
Does the DP83815DUJB/NOPB support connection to an external PHY?
Yes, the DP83815DUJB/NOPB supports external PHY connection via the Media Independent Interface (MII). When CFG:EXT_PHY is enabled, the internal PHY is disabled and MII signals (RXD[3:0], TXD[3:0], MDC, MDIO, etc.) become active - allowing use with third-party PHYs for specialized media or regulatory compliance.
What power management features does the DP83815DUJB/NOPB provide?
The DP83815DUJB/NOPB supports PCI Power Management Specification v1.1 with D0–D3cold states, Clkrun functionality, and Wake-on-LAN (WOL). In WOL mode, it consumes 380 mW and detects Magic Packet™, directed frames, ARP requests, VLAN tags, and PHY status changes - meeting PC98/PC99 OnNow requirements.
How is configuration data loaded into the DP83815DUJB/NOPB at startup?
Configuration data (MAC address, PHY settings, WOL filters) is auto-loaded from an external 93C46-compatible serial EEPROM via the MA3/EEDI, MA4/EECLK, and MD4/EEDO pins at power-on reset. This eliminates manual programming and enables field-updatable configurations without modifying firmware.
What package type is used for the DP83815DUJB/NOPB, and what are its key mechanical characteristics?
The DP83815DUJB/NOPB uses a 160-pin LBGA (UJB160A) package with 1.0 mm ball pitch and 13.0 mm × 13.0 mm body size.
