The KSZ8851 is a single-port controller chip with a SPI or 8-/16-/32-bit non-PCI CPU interface. Available in 32-/48-/128-pin packages, the KSZ8851 is for applications requiring cost-effective, high-throughput Ethernet connectivity in traditional embedded systems with MCUs or MPUs.
Integrated MAC and PHY Ethernet Controller
Designed for high performance and high throughput applications
Supports 10BASE-T/100BASE-TX
Supports full-duplex flow control and half-duplex back pressure 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
