KSZ8851SNL General Description

The KSZ8851SNL is an Ethernet controller manufactured by Microchip Technology (formerly Micrel). It's a highly integrated, single-port 10/100 Ethernet controller designed for embedded applications requiring Ethernet connectivity.

Key Features

Integrated MAC and PHY Ethernet Controller 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 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
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
Shared data bus for Data, Address and Byte Enable
Efficient architecture design with configurable host interrupt schemes to minimize host CPU overhead and utilization
Powerful and flexible address filtering scheme
Optional to use external serial EEPROM configuration for MAC address
Single 25MHz reference clock for both PHY and MAC
HBM ESD Rating 6kV
Single 3.3V power supply with options for 1.8V, 2.5V and 3.3V VDD I/O
Built-in integrated 3.3V or 2.5V to 1.8V low noise regulator (LDO) for core and analog blocks
Enhanced power management feature with energy detect mode and soft power-down mode to ensure low-power dissipation during device idle periods Comprehensive LED indicator support for link, activity and 10/100 speed (2 LEDs) - User programmable
Low-power CMOS design
Commercial Temperature Range: 0°C to +70°C
Industrial Temperature Range: -40°C to +85°C
Flexible package options available in 32-pin (5mm x 5mm) QFN KSZ8851SNL/SNLI, 48-pin (7mm x 7mm) LQFP KSZ8851-16MLL or 128-pin PQFP KSZ8851-16/32MQL
