General Description
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.
FEATUREs
■ 100-pin LQFP.
■ Supports processor interface: Byte/word/Dword of I/O command to internal memory data operation
■ Integrated 10/100M transceiver with 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 Auto MDIX Enable .
■ Compatible with 3.3V and 5.0V tolerant I/O
