TCP/IP Network Stack LSI
S-7600A
Hardware Specification Revision 1.3
1. Introduction
1.1. Product Overview
The S-7600A is a LSI that integrates TCP/IP network stack. It offers your devices a quicker and easier
connectivity to a network with its on-chip serial interface and a static RAM that operates as a buffer.
Implementing this LSI into your system can significantly reduce your software development cost. Also its
low operating frequency gives benefits to the power consumption.
The S-7600A also supports a microprocessor interface via the iReady iAPI^TM register set, and connection
to Physical Transport Layer Interface. iAPI consists of a set of register and operating definitions that allow
any micro controller system to interface with the internal modules.
