Preliminary
Store-and-forward operation with full error checking and filtering. Low-latency operation in both unicast and broadcast modes. Filtering and switching at wire rates (up to 148,8000 packets per second), supporting a mix of Ethernet and IEEE 802.3 protocols. Performs all address learning, address table management, and aging functions for up to 32,768 MAC addresses (limited by external memory) with an address learning rate of up to 10,000 addresses per second. Maximum broadcast/multicast rate of 14,880 packets per second per port with configurable broadcast storm rate limiting. Backpressure flow control with configurable per-port buffer thresholds and limits. Expandable to 64 ports without loss in throughput using multiple PM3350

devices via an on-chip 1 Gbit/s expansion port. Expansion port supports a peak system bandwidth of 1 Gbit/s, and is compatible with industry-standard PCI bus (version 2.1). Interfaces directly to industry-standard 10BaseT Ethernet Medium Access Unit devices (LXT944 or similar) with no glue logic. Configuration, management, MIB statistics, and diagnostics available in-band (via on-chip SNMP agent with integral TCP/UDP/IP stack). Maintains and collects per-port and per-host statistics at wire rates. Fully static CMOS operation at 50 MHz clock rates. Implemented with a 3.3 V core and a 5 V-compatible I/O. Available in a 256-pin Ball Grid Array (BGA) package.
