A 28nm Wirebond IO library with dynamically switchable 1.8V/ 3.3V GPIO, 5V I2C open-drain, 1.8V & 3.3V analog, OTP program cell, and HDMI & LVDS protection macros - featured across a variety of metal stack and pad configuration options
A key attribute of the Certus 28nm IO library is its ability to detect and dynamically adjust to a VDDIO supply of 1.8V or 3.3V during system operation. The GPIO cell set can be configured as input, output, open-source, or open-drain with an optional internal 60K ohm pull-up or pull-down resistor. Digital cells for 25MHz, 75MHz, and 150MHz allow optimization across SSO currents & power. ESD protection for VDDIO, VREF and core VDD supplies is constructed in an aggressive footprint. The library also features 5V I2C open-drain (fail-safe), a 5V OTP programming cell, and 1.8V & 3.3V analog cells. 1.8V LVDS and 3.3V, 5V tolerant fail-safe HDMI protection blocks with low-cap signal pads are also available. The library is enriched with feed-through, filler, transition and domain-break cells to allow for flexible pad ring construction.
Built into our IO libraries, and also offered as a separate service, is our strong ESD expertise. Certus was founded by ESD engineers and our results speak for themselves. Not only do we consistently exceed the standard ESD targets of 2KV HBM and 500V CDM, but we also provide on-chip solutions for standards such as IEC-61000-4-2, system-level ESD and Cable Discharge Events (CDE).
Certus supports IO libraries across multiple TSMC nodes including 180nm, 130nm, 40nm, 28nm, 22nm, and 16/12nm. Certus is particularly suited at providing custom variants in a cost-efficient framework. Please contact us for supplementary physical or electrical features that can suit your needs.
