Internet Appliance on a Chip (IAC)

 
Data Sheet
Preliminary Draft

Description

The IAC (Internet Appliance on a Chip) is an embedded microcontroller with builtin Internet functionality. This provides simple coniguration and communication between the IAC and host computers as well as several IACs. Programming is done through the builtin HTTP and FTP servers. Programs are stored in the nonvolatile RAM disk. Several serial and parallel I/O interface pins permit the control of the embedded application.
