1.5V to 3.3V GPIO with Tri-State Output Driver in GF 180nm

Overview

A GlobalFoundries 180nm BCD Lite Wirebond GPIO library with tri-state out- put driver, schmitt trigger receiver and associated ESD.

This silicon-proven, wirebond library in GlobalFoundries 180nm BCD lite is a specialty I/O similar to Soundwire. Featuring a 1.5V to 3.3V GPIO, as well as a tri-state output driver, an analog test point switch, and 7V OTP mode. The library is designed to be compliant with the following standards: I2C, I3C, DDC, CEC and SPI. ESD protection is include. ESD targets are 2kV HBM and 500V CDM. Library also features power and ground cells.
