About Certus Semiconductor

Certus Semiconductor is a Unique IO & ESD Solution Company. They have assembled several of the world’s foremost experts in IO and ESD design to offer their clients the ability to affordably tailor their IO libraries into the optimal fit for their products.

Certus works directly with you – that means they will meet with your architects, circuit & layout designers and reliability engineers to ensure that our IO and ESD solutions provide the most efficient and competitive solutions for your market space.

Take a look around, you will find that Certus is very different from the one-size-fits-all IO & ESD providers!

Digital and Analog IP

Digital I/O

Certus Semiconductor’s digital I/O solutions are capable of meeting many GPIO/ODIO standards including I2C, I3C, SPI, JECDEC CMOS, eMMC, LPDDR, SMBUS, DDC/DEC, ECEL,GTL, RGMII2, SPDIF and many more.

Analog I/O

Our Analog I/O solutions offer ultra-low capacitance, ultra ESD protection, and protection from extreme voltages. Minimizing impact on impedance and matching and signal integrity. Full libraries are also available.

RF/Analog IP

State of the art ultra-low power wireless front end technology including silicon proven RF IP, Full-Chip RF products, and next generation wireless IPs.

Specialty ESD

ESD protection that can meet your required specifications and capable of withstanding stress beyond standard HBM and CDM levels.

Certus Offers The Following Design Services

Foundries

Certus Offers A Wide Variety Of Information

Certus has silicon-proven libraries in the following foundry processes. These can be licensed off-the-shelf or can be customized for your application, and are available as full libraries or on a cell-by-cell basis.

In addition to these processes, Certus has consulted on designs in many others and can be contracted for development in any of them. Their foundry experience includes TowerJazz, DongBu HiTek, UMC, pSemi, Silanna, Lfoundry, Silterra, TSI, XFab, and Vanguard processes.

Testimonials

“The Certus team was able to use their experience to find a design solution that worked the FIRST TIME and passed our ESD requirements.”

Michael Stockinger
Technical Director, NXP

“The I/O and ESD solutions from Certus provide substantial improvement over the “standard” options.”

Paul Basset
Principal Engineer, Uhnder, Inc.

“Certus Semiconductor helped us created a FIRST SILICON success story.”

Huw Davies
CEO, Trameto 

Stephen & and the Certus Team [sic] are highly recommended.

We engaged with Stephen for (1) IO ESD expertise (2) to serve as an independent reviewer and (3) ~MHz IO designs. Stephen’s knowledge ESD designs is commendable. With his help, we were able to interpret TLP data correctly (multi-finger turn-on mechanisms) and discover weaknesses evident in the TLP curves but absent from internal reviews (insufficient NWELL contacts, e.g.)

On #1, #2: Stephen is always accessible for short/long discussions on any ESD-related topics. Our team appreciated his candor and always felt satisfied with the deep technical discussions (FA analysis, thermal runaways). We also appreciated his proposals on fixes.

On #3: For our last project, we worked with Certus Semiconductor for our IOs. Silicon shows IOs are working per expectation and based on TLP, we have excellent ESD robustness and margins.

Thanks Stephen for your support and I look forward to our next engagement.

Pruthvi Chaudri
Analog Design Manager, TDK InvenSense

We reached out to Stephen and the Certus Team for ESD consultation after failing to meet performance on our first product design. They integrated seamlessly with our design team and immediately found our issues and guided our team on the fixes. Our design update now fully meets/exceeds the spec and we are using Certus for all of our current product designs. This covers 2 Foundries and 2 Process Nodes.

Their expertise and guidance was critical to getting deep into our schematics and finding timely and sensible fixes. Certus is now a key part of our design flow to ensure our floorplans and circuit designs fully address ESD protections.y.”
