STE10/100

PCI 10/100 ETHERNET CONTROLLER

WITH INTEGRATED PHY (5V)

PRODUCT PREVIEW

1.0 DESCRIPTION

The STE10/100 is a high performance PCI Fast Eth-

ernet controller with integrated physical layer inter-

face for 10BASE-T and 100BASE-TX application.

It was designed with advanced CMOS technology to

provide glueless 32-bit bus master interface for PCI

bus, boot ROM interface, CSMA/CD protocol for Fast

Ethernet, as well as the physical media interface for

100BASE-TX of IEEE802.3u and 10BASE-T of

IEEE802.3. The auto-negotiation function is also

supported for speed and duplex detection.

PQFP128 (14x20x2.7mm)

ORDERING NUMBER: STE10/100

■

PCI bus interface Rev. 2.2 compliant

The STE10/100 provides both half-duplex and full-

duplex operation, as well as support for full-duplex

flow control. It provides long FIFO buffers for trans-

mission and receiving, and early interrupt mecha-

nism to enhance performance. The STE10/100 also

supports ACPI and PCI compliant power manage-

ment function.
