Microchip 48-Pin LQFP Ethernet Controller 3.3 V 100 Mbps Full Duplex/Half Duplex KSZ8851-16MLLI

Microchip KSZ8851-16MLLI is a high-performance Ethernet controller IC supplied in a 48-Pin LQFP surface-mount package. It operates at a maximum supply voltage of 3.3 V and supports communication speeds up to 100 Mbps with full duplex and half duplex capabilities, making it suitable for various embedded system applications requiring robust Ethernet connectivity.

This controller integrates both MAC and PHY functions, providing seamless support for IEEE 802.3u and IEEE Ethernet standards. It features flexible CPU interfaces including SPI or 8-/16-/32-bit non-PCI type, allowing easy connection to microcontrollers and microprocessors. The device supports internal loopback mode facilitating easier diagnostics during development and deployment.

It supports DMA-slave burst read and write transfers, enhancing efficiency in handling network traffic. The KSZ8851-16MLLI offloads IP header checksum calculations for IPv4 and IPv6, including TCP, UDP, and ICMP protocols, contributing to improved processor performance in network communications.

The compact LQFP package with 48 pins has dimensions of 7.1 mm by 7.1 mm footprint and 1.6 mm height, ideal for space-constrained designs. The device operates reliably over a wide temperature range from -40°C to 85°C, supported by a modest supply current of 85 mA at 3.3 V, making it suitable for industrial, automotive non-certified applications, and embedded Ethernet solutions.

The KSZ8851-16MLLI does not carry specific industry approvals but is a well-established product designed and manufactured in the United States. Its compatibility with both Big- and Little-Endian processors, support for multiple data frames in transmission and reception, and automatic CRC checks ensure high reliability in network data handling.
