Product details
Overview
DP83816AVNG-EX/NOPB 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, features 2 KB Tx/Rx FIFOs, Wake-on-LAN (WOL), and operates across 0°C to 85°C. It targets embedded SBCs requiring high-speed PCI bus connectivity with low-power 3.3V CMOS design.
For engineers reviewing the DP83816AVNG-EX/NOPB datasheet, DP83816AVNG-EX/NOPB pinout, DP83816AVNG-EX/NOPB application, or DP83816AVNG-EX/NOPB equivalent, key selection considerations include PCI V2.2 compliance, integrated PHY support for twisted-pair media, WOL event filtering (Magic Packet™, directed packets, VLAN), MII interface capability for external PHY attachment, and EEPROM auto-load configuration at power-on.
Technical Context
The DP83816AVNG-EX/NOPB integrates a PCI MAC/BIU with a fully compliant 3.3V CMOS PHY supporting both 10BASE-T and 100BASE-TX standards. Its MAC implements bus-mastering DMA with up to 128-dword bursts, reducing host CPU overhead, and includes RFC 1213/1398-compliant MIB statistics collection.
The PHY subsystem features adaptive equalization, baseline wander compensation, IEEE 802.3u Auto-Negotiation with EEPROM-configurable advertised capabilities, and supports both internal loopback and external MII interface. It delivers full-duplex flow control per IEEE 802.3x and deep packet pattern matching for up to four unique wake patterns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 10/100 Mb/s full-duplex operation with minimum interframe gap - enables simultaneous transmit/receive on standard twisted-pair cabling. |

Pinout & Package
DP83816AVNG-EX/NOPB is housed in a 144-pin LQFP package (NS package code VNG144A), with exposed thermal pad and 0.5 mm pitch. Pin functions are defined per PCI V2.2, MII, and PHY interface requirements, including dedicated signals for EEPROM access (EECLK, EEDO, EEDI), LED control (MA1/LED10N, MA2/LED100N, MA0/LEDACTN), and power management (PMEN/CLKRUNN, PWRGOOD, 3VAUX).

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 2.2 10/100 MAC only - requires external PHY; no integrated 100BASE-TX transceiver; lacks WOL pattern matching and MII management registers. | Suitable for cost-sensitive designs where external PHY is already present and advanced WOL is unnecessary. | Select if BOM flexibility and PHY independence outweigh integrated PHY convenience and enhanced power management. |
| KSZ8851-MLL | Non-PCI SPI/parallel interface; 10/100 MAC+PHY in 48-QFN; no WOL support; no MII; lower power (120 mW active) but no EEPROM auto-load. | Targeted at microcontroller-based systems with limited PCB space and no PCI bus - not drop-in replaceable. | Choose for ARM Cortex-M or RISC-V platforms needing compact, low-power Ethernet without PCI infrastructure. |
Compared with RTL8139C(L) and KSZ8851-MLL, DP83816AVNG-EX/NOPB uniquely combines PCI-native integration, full internal PHY compliance, robust WOL filtering, and MII extensibility - making it optimal for PCI-based embedded SBCs requiring minimal external components and field-upgradable link behavior.

FAQ
What is the operating temperature range of the DP83816AVNG-EX/NOPB?
The DP83816AVNG-EX/NOPB is rated for operation from 0°C to +85°C. This extended temperature range is explicitly validated in the official datasheet (SNLS275) and makes the device suitable for industrial enclosures and non-air-conditioned embedded deployments where ambient temperatures exceed commercial-grade limits. The "EX" suffix denotes this extended specification.
Does the DP83816AVNG-EX/NOPB support Wake-on-LAN with custom packet patterns?
Yes, the DP83816AVNG-EX/NOPB supports Wake-on-LAN with up to four user-defined deep packet patterns stored in on-chip memory. These patterns are matched against incoming frames while the device is in D3cold or sleep mode, enabling selective wake events beyond standard Magic Packet™ - a capability confirmed in Section 6.5.2 of the DP83816AVNG-EX/NOPB datasheet.
Can the DP83816AVNG-EX/NOPB interface with an external PHY?
Yes, the DP83816AVNG-EX/NOPB includes a fully compliant Media Independent Interface (MII) with MDIO/MDC, RXD[3:0], TXD[3:0], CRS, COL, RXDV, RXER, RXCLK, and TXCLK pins. When configured via the CFG:EXT_PHY bit, the internal PHY is disabled and the MII signals become active - allowing direct connection to external 10/100 PHYs such as the DP83840 or equivalent.
What package type and pin count does the DP83816AVNG-EX/NOPB use?
The DP83816AVNG-EX/NOPB uses a 144-pin LQFP package with NS package code VNG144A. This is explicitly stated in the "Connection Diagram" section (page 4) of the official datasheet SNLS275 and confirmed by the pin numbering diagram showing pins 1 through 144 in standard LQFP layout with thermal pad.
Is EEPROM configuration required for basic operation of the DP83816AVNG-EX/NOPB?
No, EEPROM configuration is optional but recommended. The DP83816AVNG-EX/NOPB will operate with default register values if no EEPROM is present; however, critical parameters like MAC address, Auto-Negotiation advertisement bits, and WOL enable settings must be loaded via software or EEPROM. The serial EEPROM interface (EECLK/EEDI/EEDO) supports auto-load at power-on, simplifying system initialization.
