General-Purpose I/O

eSilicon has developed a general-purpose I/O (GPIO) library catering to a wide variety of customers and market segments. Our general-purpose I/O library includes support for multiple voltages and a full set of support cells (supply, corner spacers, diode breakers, terminators) targeted for a wide range of process technologies and applications. eSilicon’s general-purpose I/O solution is carefully crafted to meet critical power, performance, area (PPA) and reliability requirements.

Our general-purpose I/O is available from 14nm to 180nm process technology. Front-end views of our 7nm general-purpose I/O are available now by contacting
