This specific IP macro is designed in TSMC 7nm and can be ported to other technologies upon request using Sofics in-house design tool flow. The 3.3V local clamp provides 2.35A TLP, 3.5kV HBM and 5A CDM performance with leakage below 50nA at 25C. Its compact 1800µm² implementation supports local protection for I/O, analog, RF and high-voltage pins.

Summary
This ESD protection IP provides robust on-chip protection for sensitive I/O, supply, and interface pins while minimizing impact on signal performance, leakage, and silicon area. The solution is designed for integration in multiple process nodes and can be adapted to specific interface requirements, voltage domains, and foundry design rules.
The protection concept supports reliable operation under HBM and CDM stress conditions and can be customized for higher robustness levels, low-capacitance interfaces, low-leakage applications, or reduced-area.
