Product details
Overview
DP83816AVNG-TI from Texas Instruments (formerly National Semiconductor) is a single-chip 10/100 Mb/s PCI Ethernet MAC and integrated physical layer (PHY) in a 144-pin LQFP package. It implements IEEE 802.3/802.3u compliant 10BASE-T and 100BASE-TX transceivers, supports full-duplex operation at both speeds, includes 2 KB Tx/Rx FIFOs, and delivers Wake-on-LAN functionality with Magic Packet™ and directed packet detection. It targets low-cost PC motherboards and embedded network interfaces.
For engineers reviewing the DP83816AVNG-TI datasheet, DP83816AVNG-TI pinout, DP83816AVNG-TI application, or DP83816AVNG-TI equivalent, key selection considerations include its integrated MacPHYTER-II™ architecture, PCI V2.2 bus mastering up to 128-dword bursts, IEEE 802.3x flow control support, MII interface for external PHY expansion, and power management compliance with ACPI v1.0 and PC99 specifications.
Technical Context
The DP83816AVNG-TI integrates a PCI Media Access Controller (MAC) with a 3.3V CMOS PHY supporting both 10BASE-T and 100BASE-TX standards. Its MAC implements full-duplex flow control per IEEE 802.3x and supports auto-negotiation via EEPROM-configurable advertised capabilities.
It features a dual-mode MII interface-disabled by default but configurable via CFG:EXT_PHY-and provides comprehensive packet filtering including perfect unicast match, 512-entry hash-based multicast/unicast filtering, and deep pattern matching for up to four user-defined byte sequences. Internal statistics collection aligns with RFC 1213 (MIB II) and IEEE 802.3 LME.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RTL8139C(L) | PCI 32-bit 33 MHz, no integrated PHY; requires external 10BASE-T PHY; lacks MII interface and advanced WOL filtering | Lower BOM cost but higher design complexity; suitable only where external PHY is already present | Choose when leveraging existing PHY infrastructure or minimizing IC count is secondary to lowest unit cost |
| DM9000AEP | Non-PCI interface (ISA/SPI); 10/100 Mbps; integrated PHY; no WOL or MII; different register map and driver model | Targeted at microcontroller-based systems with limited bus resources; not drop-in replaceable in PCI slots | Prefer for ARM/MIPS SoC designs with SPI/ISA buses where PCI footprint is unavailable |
Compared with RTL8139C(L) and DM9000AEP, DP83816AVNG-TI offers superior integration (MAC+PHY+PCI), richer WOL event support, and MII expandability-making it optimal for PCI-based embedded systems needing minimal external components and robust power-aware networking.

FAQ
What is the primary function of the DP83816AVNG-TI in a system?
The DP83816AVNG-TI serves as a complete 10/100 Mbps Ethernet controller integrating both MAC and PHY functions on a single die. It connects directly to the PCI bus for host communication and handles all physical layer signaling-including 10BASE-T and 100BASE-TX transmission, auto-negotiation, and link integrity monitoring-without requiring external PHY components. This makes DP83816AVNG-TI ideal for compact, low-cost network interface cards and embedded systems.
Does the DP83816AVNG-TI support full-duplex operation at both 10 Mb/s and 100 Mb/s?
Yes, the DP83816AVNG-TI supports full-duplex operation at both 10 Mb/s and 100 Mb/s data rates, complying with IEEE 802.3x flow control. It implements hardware-based pause frame generation and response, enabling reliable bidirectional traffic handling without collisions. The internal FIFOs (2 KB Tx, 2 KB Rx) and bus-mastering architecture ensure sustained throughput under full-duplex load, making DP83816AVNG-TI suitable for demanding network applications.
How does Wake-on-LAN work on the DP83816AVNG-TI?
The DP83816AVNG-TI implements Wake-on-LAN per PC98/PC99 and OnNow specifications, detecting Magic Packet™ frames, directed packets, VLAN-tagged packets, ARP requests, and user-defined pattern matches-even while in D3cold power state. Its dedicated PMEN/CLKRUNN pin signals the event to the system, and internal filtering logic operates independently of host CPU activity. This ensures DP83816AVNG-TI can reliably wake systems from deep sleep without external circuitry or firmware intervention.
Can the DP83816AVNG-TI interface with an external PHY?
Yes, the DP83816AVNG-TI includes a fully compliant Media Independent Interface (MII) that can be enabled via the CFG:EXT_PHY bit in its configuration registers. When activated, pins such as MDC, MDIO, RXCLK, TXCLK, and RXD[3:0]/TXD[3:0] become functional for connecting external PHY devices like the DP83820 or equivalent. This allows designers to substitute the internal PHY with alternate media options (e.g., fiber, MII-to-RMII bridges) while retaining the same MAC and PCI interface-extending DP83816AVNG-TI's flexibility beyond copper-only deployments.
What power management standards does the DP83816AVNG-TI comply with?
The DP83816AVNG-TI complies with ACPI v1.0, PCI Power Management Specification v1.1, and OnNow Device Class v1.0a for Network Devices. It supports D0–D3cold power states, with measured consumption of 383 mW in active D0 mode, 297 mW in WOL-ready D3hot, and 53 mW in deep-sleep D3cold. Its PMEN/CLKRUNN pin and internal power state machine enable seamless OS-coordinated transitions, making DP83816AVNG-TI compatible with Windows 98/2000/XP and Linux kernel power management frameworks.
