SGIO IO T040G Library is a General Purpose IO Library (GPIO) developed in 40nm TSMC G process (equivalent to TSMC 45nm General Purpose Superb). It contains LVCMOS, LVDS, Crystal Oscillator, Analog and Power Pads along with a Power Detect cell.

The cells are implemented with TSMC G process (single poly with 9 metals). It uses SVT/HVT thin-oxide 1.0 V and 1.8 V transistors. The use of deep N-well, ESD implant and LVT transistors are not required. It operates on a core supply of 0.9 / 1.0 V and I/O supply of either 1.8 / 2.5 V or 2.5 / 3.3 V with variations as specified by JEDEC. All cells are power supply sequence independent.
