Certus is pleased to offer I2C open-drain IOs across multiple process technologies. The Certus I2C IO can support external supplies of 1.8V, 3.3V and 5V at Fast Mode (400Kbps) and Fast Mode+ (1Mbps) data rates. The Certus solution features power sequence independence, a hysteresis input, and true fail-safe operation. Fully compatible with the Certus GPIO library, this cell can be configured across a broad range of open-drain interfaces, resistive and capacitive loads. Our Open Drain IO solutions are also SMBUS, DDC, CEC and HPD compliant.
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 also offers RGMII, Secure Digital, LVDS, Analog/RF, HV and numerous other IO variants across most major foundries and technology nodes. We are particularly suited at providing customized options in a cost-efficient framework. Please contact us for supplementary physical or electrical features that can suit your needs.
