Digital I/O

In Fact, They Can Be Incredibly Powerful.

Certus Semiconductor offers numerous libraries of Digital I/Os to meet the needs of your specific project. Our Multitool specialty circuit is capable of meeting many GPIO/ODIO standards and many of our off-the-shelf libraries contain special features, like protection from extreme voltages and ESD, that can’t be done with  Foundry IP. Learn more about these features by downloading our Digital I/O brochure.

1.2/1.5/1.8/2.5/3.3/5V GPIO


Certus offers 1.8V, 3.3V, and switchable 1.8/2.5/3.3/5V General-Purpose IO (GPIO) solutions. Many features are available across various nodes, foundries, and technologies. Some of these features include ultra-low power/low leakage, multiple drive strengths (dedicated cells or selectable), Analog Test Point, One Time Program, extreme levels of ESD protection, and Rad Hard. Standards include eMMc, RGMII, ONFI, LPDDR, etc. Advanced Certus IO libraries also include a 1.8/2.5/3.3V Reduced Gigabit Media Independent Interface (RGMII) compliant IO cell.

ODIO


Our libraries include an I2C Open Drain IO, up to 3.3V-5V tolerant, supporting Fast Mode (400Kbps) and Fast Mode+ (1Mbps) data rates. 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 cell is compliant with I2C, SMBUS, DDC, CEC and HPD.
