TSMC 55nm is a GPIO Library with specialized interface capabilities.

Our latest release on TSMC 55nm is a GPIO Library with specialized interface capabilities such as MIPI Soundwire and I2C. These deluxe cells include trimmable timing, clock phase selector, multiple input/output/ hi-Z modes, power down mode, analog test points, and ultra-low leakage regardless of power sequencing. A GPIO with a high-Voltage feature for VPP programming up to 6.5V is also available. Powers include a Core supply down to 0.9V and IO supply up to 1.8V. It is silicon-proven and passes 4kV HBM.
