Product details
Overview
DP83816AVNG/NOPB 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, internal 2KB TX/RX FIFOs, and full-duplex 10/100BASE-TX/10BASE-T operation with auto-negotiation - deployed in PC motherboards and embedded network interface cards.
For engineers reviewing the DP83816AVNG/NOPB datasheet, DP83816AVNG/NOPB pinout, DP83816AVNG/NOPB application, or DP83816AVNG/NOPB equivalent, key selection considerations include PCI bus mastering capability, integrated PHY support for twisted-pair media, Wake-on-LAN compliance (PC98/PC99/SecureOn), EEPROM-based configuration loading, and low-power 3.3-V CMOS operation with 383 mW typical active power draw.
Technical Context
The DP83816AVNG/NOPB integrates a PCI V2.2 bus interface with burst transfers up to 128 dwords and supports PCI power management (Clkrun, PME, D3 state). Its internal PHY implements ANSI X3.263-compliant TP-PMD with adaptive equalization and baseline wander compensation for 100BASE-TX, plus IEEE 802.3 10BASE-T transceiver with integrated filters.
It features flexible packet filtering (single-address perfect match with MSb masking, 512-entry multicast/unicast hash table, deep pattern matching for four patterns), MII interface for external PHY attachment, and statistics gathering per RFC 1213, RFC 1398, and IEEE 802.3 MIB II.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10/100 Mb/s 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 WoL packet filter granularity | Lower BOM cost but requires host driver initialization of MAC address and PHY registers | Preferred where driver support and cost dominate over out-of-box configurability |
| KSZ8841-16MQL | Microchip 10/100 PCI-to-SMI bridge with external PHY; no integrated PHY, smaller 128-pin QFP package | Requires external PHY but offers greater PHY selection flexibility and lower thermal density | Chosen when system-level PHY customization (e.g., fiber, PoE) or thermal constraints preclude integrated solutions |
Compared with RTL8139D-GR and KSZ8841-16MQL, DP83816AVNG/NOPB provides tighter integration (MAC+PHY+EEPROM loader in one LQFP), deterministic WoL behavior per PC99 spec, and reduced host initialization burden - making it optimal for PC-class and embedded designs prioritizing time-to-market and driver compatibility.

FAQ
What is the primary function of the DP83816AVNG/NOPB in a system architecture?
The DP83816AVNG/NOPB serves as a complete 10/100 Mb/s Ethernet controller, integrating both the Media Access Controller (MAC) and Physical Layer (PHY) into a single device. It connects directly to the PCI bus for host communication and interfaces with twisted-pair cabling via its built-in 10BASE-T/100BASE-TX transceivers. In system architecture, DP83816AVNG/NOPB handles frame transmission/reception, CRC generation/checking, auto-negotiation, and physical signaling - eliminating the need for separate MAC and PHY chips.
Does the DP83816AVNG/NOPB support PCI power management features such as Clkrun and PME?
Yes, the DP83816AVNG/NOPB fully supports PCI power management per ACPI v1.0, PCI Power Management Specification v1.1, and OnNow Device Class v1.0a. Its PMEN/CLKRUNN pin provides dual-function support: PME assertion for wake events and Clkrun signaling to gate PCICLK during idle periods. The device enters low-power sleep mode drawing only 53 mW and maintains WoL readiness at 297 mW - all compliant with PC98 and PC99 hardware design guides.
How does the DP83816AVNG/NOPB handle MAC address storage and initialization?
The DP83816AVNG/NOPB supports automatic MAC address loading from an external serial EEPROM (e.g., NM93C46) via its EESEL/EECLK/EEDI/EEDO interface at power-on reset. Configuration data - including MAC address, WoL enable bits, and PHY settings - is loaded without host CPU intervention. If CFGDISN is pulled low, EEPROM loading is disabled and the device defaults to factory-programmed or software-configured values. This ensures deterministic bring-up in headless embedded systems.
Can the DP83816AVNG/NOPB operate with an external PHY instead of its integrated one?
Yes, the DP83816AVNG/NOPB includes a standard Media Independent Interface (MII) compliant with IEEE 802.3u, allowing connection to external PHY devices. When EXT_PHY is enabled in the CFG register, the internal PHY is disabled and MII signals (TXD/RXD, TXEN, RXDV, CRS, COL, TXCLK, RXCLK, MDIO, MDC) become active. This mode supports PHY substitution for specialized media (e.g., fiber, AUI) or custom signal conditioning not provided by the integrated 10/100 twisted-pair PHY.
What thermal and power specifications apply to the DP83816AVNG/NOPB under normal operation?
The DP83816AVNG/NOPB operates within 0°C to 70°C ambient temperature and draws 116–140 mA typical supply current at 3.3 V, equating to 383 mW nominal power dissipation. Thermal resistance is RθJA = 47.2°C/W (junction-to-ambient) in the 144-pin LQFP package. In Wake-on-LAN standby, current drops to 90–105 mA (297 mW); in sleep mode, it falls to 16–20 mA (53 mW). These values are measured with unloaded CMOS outputs and align with JEDEC JESD51-2A testing conditions.
