Key attributes of our TSMC 65nm IO library include dual independent IO supply rails (1.0V-3.3V & 3.3V) and power-on-control (POC) to place IOs in a low-power HiZ state during power-down. The GPIO cell can be configured as input, output or open-drain with a Schmitt trigger input and optional internal 55K ohm pull-up or pull-down resistor. ESD protection for two independent IO supplies and core power is constructed in an aggressive footprint. A specialty output cell with matched throughput timings for pulse-width modulation (PWM) applications, along with 5V OTP programming, I2C & SVID open-drain and 3.3V & 5V analog cells complement the GPIO offering. The library is enriched with filler, corner and domain-break cells in digital and analog domains 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, 65nm, 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.
