LH79524/LH79525
Ethernet MAC Controller
compatible with IEEE 802.3, and has passed the Uni-
versity of New Hampshire (UNH) testing. It supports
both 10- and 100-Mbit/s, and full and half duplex oper-
ation. Other features include:
• Statistics counter registers for RMON/MIB
• MII interface to the physical layer
• Interrupt generation to signal receive and transmit
• Transmit and receive FIFOs
• Automatic pad and CRC generation on transmitted
• Automatic discard of frames received with errors
• Address checking logic supports up to four specific
• Supports promiscuous mode where all valid
• Hash matching of unicast and multicast destination
• Supports physical layer management through MDIO
• Supports serial network interface operation
• Support for:
• Multiple buffers per receive and transmit frame
• Software configures the MAC address
• Jumbo frames of up to 10,240 bytes supported.
I
interface capable of operating in either Master or Slave
mode. The block conforms to the I
cation for data rates up to 400 kbit/s. The two wires are
SCL (serial clock) and SDA (serial data). The I
ule provides the following features:
• Two-wire synchronous serial interface
• Operates in both the standard mode, for data rates
• Communicates with devices in the fast mode as well
