Introduction
1.1
General Description
The TC5299J is a 10/100 PCMCIA Ethernet controller, include a standard MII interface. It provides an 8/16-bit
PCMCIA interface to host CPU and buffer memory into single chip to minimize the chip gate count.
The TC5299J supports both half-duplex and full-duplex (both 10BT or 100BTX) operation environment.

Features
!"PCMCIA 2.01 bus interface.
!"Use serial EEPROM 93C56/66 to store CIS.
!"Internal 5V to 3.3V regulator.
Ethernet LAN features:
!"Integrated Fast Ethernet MAC and SRAM in one chip.
!"Supports both 10Mbps and 100Mbps operation.
!"IEEE 802.3/802.3u compatible.
!"Full-duplex or half-duplex operation supported for both 10Mbps and 100Mbps operation.
!"NE2000 register definitions.
!"Supports 3.3V or 5V signaling environment.
!"The size of built-in Buffer RAM is 8k x 16 bits. It does not need the extra SRAM in the application circuit.
!"Supports loop-back mode for self-testing.
!"Supports 256/512 bytes EEPROM interface.
!"LED interface supported.
!"Supports MII bus interface.
