Micrel Evaluation Board KSZ8851SNL-EVAL

The KSZ8851 is a single-chip Fast Ethernet controller consisting of a 10/100Base-T physical layer transceiver (PHY), a MAC, and a microprocessor interface.

Integrated MAC and PHY Ethernet controller fully compliant with IEEE 802.3/802.3u standards
Designed for high performance and high throughput applications
Supports 10Base-T/100Base-TX
Supports IEEE 802.3x full-duplex flow control and half-duplex backpressure collision flow control
Supports DMA-slave burst data read and write transfers
Supports IP Header (IPv4)/TCP/UDP/ICMP checksum generation and checking
Automatic 32-bit CRC generation and checking
Simple SRAM-like host interface easily connects to most common embedded MCUs
Supports multiple data frames for transmit and receive without address bus and byte-enable signals
Supports both Big- and Little-Endian processors
Larger internal memory with 12KBytes for RX FIFO and 6K Bytes for Tx FIFO
Programmable low, high and overrun watermark for flow control in Rx FIFO
Efficient architecture design with configurable host interrupt schemes to minimize host CPU overhead and utilization
Powerful and flexible address filtering scheme
Single 25MHz reference clock for both PHY and MAC
