Integrated Circuit Chip W3100A-LF - WIZNET - i2Chip W3100A



Detailed Product Description

Quick Detail:

i2Chip W3100A


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.
The W3100A contains TCP/IP Protocol Stacks such as TCP, UDP, IP, ARP and ICMP protocols, as well as Ethernet protocols such as Data Link Control and MAC protocol.
The W3100A offers a socket API (Application Programming Interface) that is similar to the windows socket API. The chip offers Intel and Motorola MCU (8051, i386, 6811 tested) bus interface and I2C for upper-layer and supports standard MII interface for under-layer Ethernet.
The W3100A can be applied to handheld devices including Internet phones, VoIP SOC chips, Internet MP3 players, handheld medical devices, LAN cards for Web servers, cellular phones and many other nonportable electronic devices such as large consumer electronic products.
