DM9102D: Single Chip PCI Fast Ethernet NIC Controller
The DM9102D is a fully integrated and cost effective single chip Fast Ethernet NIC controller. It is designed with low power and high performance process. It is a 2.5/3.3V device with 5V tolerance. The DM9102D provides direct interface to the PCI bus and supports bus master mode to achieve the high performance of the PCI bus. It fully complies with PCI 2.2. In the media side, the DM9102D interfaces to the UTP3, 4, 5 in 10Base-T and the UTP5 in 100Base-TX. It is fully compliant with the IEEE 802.3u Spec. The auto-negotiation and HP Auto-MDIX function can automatically configure the DM9102D to take the maximum advantage of its abilities.
Features
- Current consumption 90mA + 40mA transformer
- 0.25 µm Process
- Integrated 10/100 Auto MDI-X Transceiver
- Up to 100MHz system clock
- Compatible to IEEE802.3u
- IP/TCP/UDP checksum generation and checking
- Supports early TX
- 4k Dword SRAM
- Temperature Range: 0°C to 70°C
- Integrated 3.3V to 2.5V converter
- Processor interface: Byte/Word/Dword
- SPI EEPROM interface
- MII and Reverse-MII interface
- Wake-on-LAN
The DM9102D also supports IEEE 802.3x’s full-duplex flow control to prevent the receive overflow of link partner. The IPv4 IP/TCP/UDP checksum generation and checking can reduce the system CPU utilization. The DM9102D supports two types of power management mechanisms. The main mechanism is based on the OnNow architecture, which is required for PC99. The alternative mechanism is based upon the remote Wake-On-LAN mechanism.
