This library is a production-ready I/O library built on the TSMC 12nm process. The library features 1.8V to 3.3V GPIOs with programmable drive strength, hysteresis, and control logic. It includes support cells for all power domains: 0.8V, 1.8V, and I/O and incorporates latch-up immune, JEDEC-compliant ESD structures. The library is designed for flip-chip packaging and includes vertical and horizontal variants to support all die edge orientations. All power domains include integrated power-on control (POC) cells for safe and reliable sequencing.
