1.8V Capable GPIO on Samsung Foundry 4nm FinFET
The 1.8V capable GPIO is an IP macro for on-chip integration.
Overview
The 1.8V capable GPIO is an IP macro for on-chip integration. It is a 1.8V general purpose I/O built with a stack of 1.2V MOS FINFET devices. It is controlled by 0.75V (core) signals.
Supported features include core isolation, output enable and pull enable. Extra features such as input enable/disable, programmable drive strength and pull select, can be supported upon request.
By default, a 2kV HBM ESD protection is included. This is however easily scaled to any desired level. This specific IP macro is designed in Samsung 4nm FINFET, and can be ported to other technologies upon request using Sofics inhouse design tool flow.
