Advanced Micro Devices AM79C960
The PCnet-ISA controller, a single-chip Ethernet controller, is a highly integrated system solution for the PC-AT Industry Standard Architecture (ISA ) architecture. It is designed to provide flexibility and compatibility with any existing PC application.GENERAL DESCRIPTION
This highly integrated 120-pin VLSI device is specifically designed to reduce parts count and cost, and addresses applications where higher system throughput is desired. The PCnet-ISA controller is fabricated with AMD’s advanced low-power CMOS process to provide low stand by current for power sensitive applications. The PCnet-ISA controller is a DMA-based device with a dual architecture that can be configured in two different Publication# 16907 Rev. B Issue Date: May 1994 Amendment /0 operating modes to suit a particular PC application. In the Bus Master Mode all transfers are performed using the integrated DMA controller. This configuration enhances system performance by allowing the PCnet-ISA controller to bypass the platform DMA controller and directly address the full 24-bit memory space. The implementation of Bus Master Mode allows minimum parts count for the majority of PC applications. The PCnet-ISA controller can be configured to perform Shared Memory operat...
