Description
The i2Chip W3100A is an LSI of hardware protocol stack that provides an easy, low-cost solution for high-speed Internet connectivity for digital devices by allowing simple installation of TCP/IP stack in the hardware.
The W3100A offers system designers a quick, easy way to add Ethernet networking functionality to any product. Implementing this LSI into a system can completely offload Internet connectivity and processing standard protocols from the system, thereby significantly reducing the software development cost.
