Overview

A TSMC 28nm HPM/HPC/HPC+ Wirebond I/O Library with a switchable 1.8V/3.3V GPIO, 5V I2C ODIO, 1.8V & 3.3V Analog Cells, ESD and more.

A key attribute of this silicon-proven library is to detect and adjust to a VDDIO supply of 1.8V or 3.3V during system operation. The GPIO can be configured as input, output, open-source, or open-drain with an optional 60kohm pull-up or pull-down resistor. Digital cells for 25MHz, 75MHz, and 150MHz allow optimization across SSO currents & power. Cells for I/O, core power & ground with built-in ESD circuitry are included. The library also features 5V I2C ODIO (fail-safe), 5V OTP cell, and 1.8V & 3.3V Analog cells with ESD protection. The library also includes 1.8V LVDS, 3.3V & 5V tolerant HDMI protection blocks with low-cap signal pads. The library’s filler, transition, and break cells allow for flexible pad ring construction. The library meets 2kV HBM, 500V CDM, and 2kV IEC 61000-4-2 standards.
