File Size : 116 KB Manufacturer:TI Description:The innovASIC IA21140AF Fast Ethernet LAN controller provides a direct interface connection to the PCI (Peripheral Component Interface) bus. It interfaces with the PCI bus by using on-chip control and status registers (CSRs), and a shared CPU memory area. The memory is initialized once during setup to minimize CPU overhead during normal operation. Large receive and transmit FIFOs are contained on-chip so no additional on board memory is required. The IA21140AF includes two on chip direct memory access (DMA) controllers with programmable burst size providing for low CPU utilization. A PCI clock frequency from dc to 33 MHz (20-33 MHz for operational network interface) is supported. Two network ports are supported. A serial standard 7- wire 10-Mbps port (SRL) and a media independent interface/symbol 10/100-Mbps port (MII/SYM). The 10 Mbps implements a direct interface to the external 10 Mbps front-end decoder (ENDEC). The 10/100 Mbps port supports two modes. The first is a 100BASE-X physical coding sublayer (PCS). The second is a full implementation of the MII standard. The IA21140AF functions in a full-duplex environment for either network port.
