Two additional independent HDLC controllers
Fast load and unload features for FIFOs
SS7 support for FISU transmit and receive
Independent 128-byte Rx and Tx buffers with interrupt support
Access FDL, Sa, or single/multiple DS0 channels
DS0 access includes Nx64 or Nx56
Compatible with polled or interrupt driven environments
Bit-oriented code (BOC) support
CIR Rate controller limits transmission of data from the Ethernet interface to the serial interface
CIR granularity at 512kbit/s
CIR averaging for smoothing traffic peaks
Interface for 128Mb, 32-bit-wide SDRAM
SDRAM Interface speed up to 100MHz
Auto refresh timing
Automatic precharge
Master clock provided to the SDRAM
No external components required for SDRAM connectivity
MAC port with standard MII (less TX_ER) or RMII
10Mbps and 100Mbps Data rates
Configurable DTE or DCE modes
Facilitates auto-negotiation by host microprocessor
Programmable half and full-duplex modes
Flow control for both half-duplex (back-pressure) and full-duplex (PAUSE) modes
Programmable Maximum MAC frame size up to 2016 bytes
Minimum MAC frame size: 64 bytes
Discards frames greater than programmed maximum MAC frame size and runt, nonoctet bounded, or
bad-FCS frames upon reception
Configurable for promiscuous broadcast-discard mode.
Programmable threshold for SDRAM queues to initiate flow control and status indication
MAC loopback support for transmit data looped to receive data at the MII/RMII interface
