Key attributes of the GlobalFoundries 65nm IO library are dual selectable drive strengths and independent input & output enable / disable. The GPIO cell can be configured as input, output or open-drain with a Schmitt trigger input and selectable internal 60K ohm pull-up or pull-down resistor. ESD protection for IO and core supplies is constructed in an aggressive footprint. 2.5V LVDS RX & TX cells capable of data rates up to 1.5Gbps (with no external reference) and a 2.5V low-capacitance analog/RF cell complement the GPIO offering. The library is enriched with filler, corner 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 additional IO libraries in GlobalFoundries technologies, as well as at TSMC and Samsung. 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.
