DM9010 10/100 Mbps Single Chip Ethernet Controller with General Processor Interface

The DM9010 is a fully integrated and cost-effective single chip Fast Ethernet MAC controller with a general processor interface, a 10/100M PHY and 16K Byte SRAM. It is designed with low power and high performance process that support 3.3V with 5V tolerance. The DM9010 also provides a MII interface to connect HPNA device or other transceivers that support MII interface. The DM9010 supports 8-bit, 16-bit and 32-bit uP interfaces to internal memory accesses for different processors.

• 100-pin LQFP.
• Supports processor interface: Byte/word/Dword of I/O command to internal memory data operation.
• Integrated 10/100M transceiver with HP Auto-MDIX
• Supports MII and reverses MII interface
• Supports back pressure mode for half-duplex mode flow control
• IEEE802.3x flow control for full-duplex mode
• Supports wakeup frame, link status change and magic packet events for remote wake up
• Integrated 16K Byte SRAM
• Build in 3.3V to 2.5V regulator
• Supports early Transmit
• Supports IP/TCP/UDP checksum generation and checking
• Supports automatically load vendor ID and product ID from EEPROM
• Supports 7 or 23 GPIO pins
• Optional EEPROM configuration

• Very low power consumption mode:
  – Power reduced mode (cable detection)
  – Power down mode
  – Selectable TX drivers for 1:1 or 1.25:1 transformers for additional power reduction.
  – 1: 1 transformers only when HP Auto-MDIX Enable .
• Compatible with 3.3V and 5.0V tolerant I/O

The PHY of the DM9010 can interface to the UTP3, 4, 5 in 10Base-T and UTP5 in 100Base-TX. It is fully compliant with the IEEE 802.3u Spec. Its auto-negotiation function will automatically configure the DM9010 to take the maximum advantage of its abilities. The DM9010 also supports IEEE 802.3x full- duplex flow control. This programming of the DM9010 is very simple, so user can port the software drivers to any system easily.
