W5100S-L
Overview
The W5100S-L is an embedded Ethernet controller that provides an easy way to add internet connectivity to embedded systems. It integrates a 10/100 Base-T/TX Ethernet PHY and supports various hardwired Internet protocols, offloading network processing from the host MCU. This controller features an internal 16KB memory for TX/RX buffers and can be controlled via SPI or a Parallel System Bus interface.
Why Choose This Part
This Ethernet controller simplifies network integration by handling standard internet protocols in hardware, reducing the processing load on the host microcontroller. Its 16KB internal memory for TX/RX buffers and support for both SPI and Parallel interfaces offer design flexibility. The integrated PHY and features like Wake on LAN and Power Down mode contribute to efficient and power-conscious network solutions.
