Features
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
Supports IPv6 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 12K Bytes 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

and 3.3V VDD I/O
Built-in integrated 3.3V or 2.5V to 1.8V low noise
regulator for core and analog blocks
Enhanced power management feature with energy
detect mode and power-down mode to ensure low-
power dissipation during device idle periods
Comprehensive LED indicator support for link, activity,
full/half duplex, and 10/100 speed (4 LEDs)
– User programmable
Low-power CMOS design
Commercial Temperature Range: 0oC to +70oC
Industrial Temperature Range: –40oC to +85oC
Flexible package options available in 128-pin PQFP
KSZ8851-16/32MQL or 48-pin LQFP KSZ8851-16MLL
