Product details
Overview
DP83816AVNG from Texas Instruments 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-compliant MAC, PCI V2.2 bus interface, full-duplex 10/100-Mb/s operation, internal 2 KB TX/RX FIFOs, and Wake-on-LAN support. It targets PC motherboards and embedded network interface cards requiring low-cost, self-contained Ethernet connectivity.
For engineers reviewing the DP83816AVNG datasheet, DP83816AVNG pinout, DP83816AVNG application, or DP83816AVNG equivalent, this page delivers verified technical context, validated pin functions, confirmed power and timing specifications, and real-world deployment guidance for legacy PCI-based Ethernet designs.
Technical Context
The DP83816AVNG integrates a PCI bus interface with burst-capable bus mastering up to 128 dwords, enabling zero-copy packet transfers and reducing CPU overhead. Its internal PHY supports both 10BASE-T and 100BASE-TX over twisted-pair media with auto-negotiation, adaptive equalization, and baseline wander compensation per ANSI X3.263.
It features configurable Rx packet filtering-including perfect unicast match with MSb masking, 512-entry multicast/unicast hash table, and deep pattern matching for up to four unique byte patterns-alongside RFC 1213 and RFC 1398 MIB-II statistics gathering for network management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10/100 Mbps PCI Ethernet controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RTL8139D-GR | Realtek 10/100 PCI MAC+PHY; lacks integrated EEPROM auto-load and has different MII register map | Requires external EEPROM initialization logic; no native WoL pattern match beyond Magic Packet™ | Lower BOM cost but demands additional firmware initialization and lacks DP83816AVNG's deep packet filter flexibility |
| KSZ8841-ML | Microchip 10/100 PCI-to-MII bridge (no integrated PHY); requires external PHY and separate clock domain management | Offers greater PHY selection freedom but increases board area, power, and design complexity | Preferred when PHY customization (e.g., fiber, PoE, extended reach) is required; not a drop-in replacement |
Compared with RTL8139D-GR and KSZ8841-ML, the DP83816AVNG provides tighter MAC-PHY timing integration, built-in WoL intelligence, and hardware-assisted Rx filtering-making it optimal for cost-sensitive, space-constrained PCI Ethernet implementations where full PHY integration and low-power standby are critical.

FAQ
What is the primary function of the DP83816AVNG?
The DP83816AVNG is a fully integrated 10/100 Mbps PCI Ethernet Media Access Controller and Physical Layer device. It combines MAC logic, PCI bus interface, and a compliant 10BASE-T/100BASE-TX PHY in one chip. The DP83816AVNG handles frame transmission/reception, auto-negotiation, CRC calculation, collision detection, and differential signaling-all without requiring external PHY components.
Does the DP83816AVNG support Wake-on-LAN functionality?
Yes, the DP83816AVNG supports comprehensive Wake-on-LAN (WoL) per PC98, PC99, SecureOn, and OnNow specifications. It responds to Magic Packet™ frames, directed packets, ARP requests, VLAN-tagged packets, pattern-matched payloads, and PHY link status changes. The DP83816AVNG consumes only 297 mW in WoL standby mode, enabling low-power network presence.
What package type and pin count does the DP83816AVNG use?
The DP83816AVNG uses a 144-pin LQFP (PGE) package with nominal dimensions of 20.00 mm × 20.00 mm. It includes dedicated pins for PCI bus signaling (AD[31:0], PCICLK, FRAMEN), MII interface (RXD/TXD, RXDV, TXEN), PMD differential pairs (TPTDP/TPRDM), EEPROM loading (EECLK/EEDI/EEDO), and LED status outputs (LEDACT, LED10LNK, LED100LNK).
Can the DP83816AVNG operate with an external PHY instead of its internal one?
Yes, the DP83816AVNG 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], RXDV, TXEN, CRS, COL, RXCLK, TXCLK, MDIO, MDC) become active. This allows use of alternative PHYs while retaining the DP83816AVNG's MAC, PCI interface, and filtering capabilities.
What are the key power supply requirements for the DP83816AVNG?
The DP83816AVNG requires a nominal 3.3-V ±0.3-V supply (VDD) with typical operating current of 116–140 mA. It also needs isolated AUXVDD (3.3 V) for analog PHY sections and PCIVDD (3.3 V) for PCI I/O. The DP83816AVNG specifies absolute maximum ratings up to 3.6 V and supports 5-V tolerant inputs. Decoupling requires parallel 10-µF and 0.1-µF capacitors on C1.
