Description

The RTL8703AS is a highly integrated electronic component that functions as a Fast Ethernet controller. It is a cost-effective option that provides a 32-bit performance and full compliance with IEEE 802.3u 100Base-TX specifications. This component is designed to support the Advanced Configuration Power management Interface (ACPI), PCI power management, and supports Wake-On-LAN function for remote wake-up.

Specifications and features

• 100 pin LQFP
• 10 Mb/s and 100 Mb/s operation and N-way Auto-negotiation operation
• Compliant with PCI Revision 2.2 and supports PCI clock 16.75MHz-40MHz
• Supports PCI VPD (Vital Product Data) and ACPI, PCI power management
• Supports 4 Wake-On-LAN signals, aux power-on internal reset, and auxiliary power auto-detect
• Supports a 32-bit general-purpose timer with the external PCI clock as the clock source to generate timer-interrupt
• Contains two large independent receive and transmit FIFOs and a programmable PCI burst size and early Tx/Rx threshold
• Supports Full Duplex Flow Control (IEEE 802.3x)
• Interface for 128K byte (max) Boot ROM for both EEPROM and Flash Memory
• MC’97 compatible digital controller chip and AC’97 v 2.2 compliant for full-duplex operation
• Low latency GPIO updated and 8 double-WORD FIFO depth for each bus master of LINE1-OUT/IN
• 3.3V power supply, 3.3V and 5V I/O tolerance

Application Scenarios

The RTL8703AS can be used in various applications such as desktop computers, laptops, network interface cards, and other electronic equipment that require Fast Ethernet connectivity.
