On-chip ESD IP and expertise

Enable higher performance
Increase ESD robustness
Reduce time and cost

Sofics IP and solutions extend
the foundry GPIO library.

Most foundries provide GPIO libraries for free. These libraries contain power/ground cells, analog I/Os, digital I/Os. However, for some applications the general purpose library introduces limitations. Sofics developed solutions to extend the GPIO libraries. This page compares the solutions available from Sofics with those available from the foundry.

Coverage of supply and I/O options

Sofics analog I/O and ESD protection solutions extend the foundry libraries. Both for power clamp protection and for I/Os Sofics ESD protection provides additional solutions.

General supplies
Low power / low leakage options
Interdomain interfaces

While general purpose analog I/Os are suitable for most interfaces, high-speed communication (Wired, wireless or optical) needs a special solution. The traditional ESD concepts introduce a lot of parasitic capacitance. Sofics has created ESD protection with low-parasitic capacitance to enable higher datarates.
