Sdram Interface, MAC Interface | Maxim DS33Z41 guide

DS33Z41 Quad IMUX Ethernet Mapper

2.6SDRAM Interface

•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

2.7MAC Interface

•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, non-octet bounded, or bad-FCS frames upon reception

•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

2.8Microprocessor Interface

•8 bit data bus

•Non-multiplexed Intel and Motorola Timing Modes

•Internal software reset and External Hardware reset input pin

•Global interrupt output pin

2.9Test and Diagnostics

•IEEE 1149.1 Support

•Programmable on-chip Bit Error Rate Tester (BERT)

•Patterns include Pseudorandom QRSS, Daly, and user-defined repetitive patterns

•Loopbacks (remote, local, analog, and per-channel loopback)
