Product details
Overview
DP83815DVNG/NOPB from Texas Instruments (formerly National Semiconductor) is a single-chip 10/100 Mb/s PCI Ethernet MAC + PHY (MacPhyter™) in 144-pin LQFP. It integrates IEEE 802.3/802.3u-compliant MAC, 3.3V CMOS PHY, 2 KB Tx/Rx FIFOs, and Wake-on-LAN support. Designed for low-cost PC motherboards and embedded network interfaces requiring full-duplex operation, auto-negotiation, and MII extension capability.
For engineers reviewing the DP83815DVNG/NOPB datasheet, DP83815DVNG/NOPB pinout, DP83815DVNG/NOPB application, or DP83815DVNG/NOPB equivalent, key selection considerations include PCI V2.2 compliance, integrated 10BASE-T/100BASE-TX transceivers, WOL packet filtering (Magic Packet™, directed, VLAN), EEPROM auto-load configuration, and power management across D0–D3cold states.
Technical Context
The DP83815DVNG/NOPB implements a PCI bus-mastering MAC/BIU with burst transfers up to 128 dwords (512 bytes), supporting both host-initiated and descriptor-driven DMA operations. Its internal PHY includes adaptive equalization, baseline wander compensation, and full IEEE 802.3u auto-negotiation with configurable advertisement via EEPROM.
It features dual-mode LED control (MA1/LED10N, MA2/LED100N), MII interface for external PHY attachment (enabled via CFG:EXT_PHY), and hardware-accelerated Rx packet filtering - including perfect unicast match with MSb masking, 512-entry multicast/unicast hash table, and deep pattern matching for up to four user-defined byte sequences.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet MAC+PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RTL8139C(L) | PCI 32-bit 33 MHz, no integrated 100BASE-TX PHY; requires external PHY or uses 10BASE-T-only analog front-end. | Lacks full 100 Mb/s integration; limited WOL filter types (no VLAN/ARP pattern match); no MII management interface. | Choose when cost sensitivity outweighs 100 Mb/s requirement and external PHY is acceptable. |
| KS8842-16MQL | 16-bit ISA/PCI bridge; integrated 10/100 PHY but lacks PCI bus mastering; relies on programmed I/O or shared memory DMA. | No native descriptor-based DMA; higher CPU utilization; no RFC-aligned MIB engine; limited power management (no D3cold). | Prefer for ISA-bus legacy systems or where PCI bus mastering is not required. |
Compared with RTL8139C(L) and KS8842-16MQL, DP83815DVNG/NOPB delivers superior integration (single-chip 10/100 PHY), lower host overhead (bus-mastering DMA), richer WOL filtering, and standards-aligned power management - making it optimal for new PCI-based embedded designs demanding full feature parity with PC-class NICs.

FAQ
What is the function of the PMEN/CLKRUNN pin on DP83815DVNG/NOPB?
The PMEN/CLKRUNN pin on DP83815DVNG/NOPB serves dual roles: as PMEN, it asserts a low-power management event signal (PME#) upon WOL triggers like Magic Packet™ reception; as CLKRUNN, it signals PCI clock suspension in mobile designs. Function selection is controlled by bit 0 of the CLKRUN Control/Status Register (CCSR), with default behavior set to PMEN mode at power-up.
Does DP83815DVNG/NOPB support external PHY devices via MII?
Yes, DP83815DVNG/NOPB supports external PHY attachment through its Media Independent Interface (MII). When CFG:EXT_PHY is enabled (bit 7 of Configuration Command and Status Register), the MII pins (MDIO, MDC, RXD[3:0], TXD[3:0], CRS, COL) become active and tri-state the internal PHY interface. This allows use of alternative PHYs while retaining MAC functionality and register compatibility.
How does DP83815DVNG/NOPB handle Wake-on-LAN packet filtering?
DP83815DVNG/NOPB implements hardware-accelerated WOL filtering that operates independently of host CPU activity. It detects Magic Packet™ frames (with 6×0xFF followed by 16×MAC address), directed unicast, VLAN-tagged, ARP, and user-defined pattern-match packets. Filtering occurs in D3hot/D3cold states using on-chip comparators and hash logic, enabling selective wake without full system power-up.
What are the power consumption characteristics of DP83815DVNG/NOPB in different operational modes?
DP83815DVNG/NOPB exhibits three defined power states: D0 (active mode, 561 mW typical), WOL mode (380 mW, PHY active with selective packet detection), and D3cold (sleep mode, 33 mW, all clocks and analog blocks disabled except PME# detection). These values reflect 3.3V supply operation at 25°C and align with PCI Power Management Specification v1.1 requirements.
Is DP83815DVNG/NOPB compatible with standard PCI BIOS and operating system drivers?
Yes, DP83815DVNG/NOPB is fully compatible with standard PCI enumeration and widely supported by legacy OS drivers, including Microsoft Windows NT/2000/XP NDIS miniport drivers and Linux kernel modules (e.g., drivers/net/ethernet/natsemi/natsemi.c). Its PCI configuration space adheres to V2.2 specifications, ensuring plug-and-play recognition and functional interoperability without custom driver development.
