Safe Communication Technology


Automotive Ethernet, Single-Pair-Ethernet (SPE)

Automotive Ethernet

Automotive Ethernet is the marketing name for a standard ethernet stack specified by IEEE 802.3 working group for automotive usage.

Driven by vehicle needs for high manufacturing volume, failure tolerant wiring and and low unit costs, automotive ethernet uses 2-wire single-pair communication channels. for 10 MBit/s (10BASE-T1S), 100 MBit/s (100BASE-T1), 1000 MBit/s (1000BASE-T1) and 2.5/5/10 GBit/s (MultiGigBASE-T1).

Automotive Ethernet intents to be the next generation standard automotive network communication stack, following up CAN, MOST, LIN and Flexray. It has the advantage, that it can be used with standard operating system communication stack, because only the physical layer differs from the TX ethernet stacks.

The speciality of Automotive Ethernet is the full duplex communication over 2 wires. Both nodes can send and receive data the same time. This feature is implemented in all Automotive Ethernet standards besides 10BASE-T1S, that uses a collision detection, colission avoidance algorithm or a scheduler.

Single-Pair-Ethernet (SPE)

Single-Pair-Ethernet (SPE) is the marketing name for 2-Wire-Ethernet more used in the Industry than in Automotive. it is based on the same ethernet stack than Automtive Ethernet but also uses some different flavors for the physical layer.

Besides the 100BASE-T1 and 1000BASE-T1 physical layer, SPE utilizes the 10 MBit/s communication for distances bigger than 1000 m in the standard 10BASE-T1L. This standard is mainly relevant for the process industry and is often used in comination with Ethernet Advanced Physical Layer (Ethernet-APL).

Our IPs

Single PHY image

Single PHY IP

We provide IP for IEEE 100BASE-T1 Automotive Ethernet as hard macro in a single phy configuration. This phy is fully functional and in the final qualification for customer integration.

Combo PHY Image

Combo PHY IP

The Combo PHY IP contains an IEEE 100BASE-T1 and 1000BASE-T1 Phy in an integrated module and one port with autonegotiation between the two standards. The first tape out is in Q4 2022.


For our solutions we use Globalfoundries 22FDX as standard node. This allows us to develop compliant to AEC-Q100 Grade 1, which is also supported by Globalfoundries.

All solutions will be qualified according to ISO 26262 ASIL B. We will do functional safety qualifications for Industry according to ISO 61508, Aerospace and Military standards on demand.

Customer Opportunities

  1. Off the shelf SoC Integration: A customer that develops its SoC based on 22FDX node technology can purchase our IP and integrate it off the shelf as hard macro.
  2. Different node technology SoC Integration: A customer develops its SoC in a technology different from 22FDX. Siliconally supports different technologies and will create a migration path for the required technology.
  3. SoC Development with PHY integration: A customer needs a SoC with PHY integration, but does not have the competencies of capacities to do an in-house development. In this case, we hand over the request to our shareholders from Racyics. Racyics developed a reference SoC that can be used as baseline for the custom made product.

About us

How We See the Future

Since its final foundation in 1989, the internet is the enabler for the digital transformation of all societies. Now, more than 30 years later, this transformation has reached the product and portfolio development of the world-wide economy.

All industries are at the threshold for the next level of automation. Systems that are being designed for the next 20, 30 or 40 years operate highly independent with limited need for human intervention in case of disturbances.

These systems demand highly reliable and functional safe communication between the system nodes for safe, reliable and high performance opererations.

Where We do See Us

Connectivity technology is more than bandwidth. We see our special scope in functional safety and reliability features for highly automated systems in multiple industries.

We enable safe and reliable system architectures by providing patterns that make the most benefit from our safety and reliablity features.

We do agile hardware development. We know that we don't know all future requirements, but we will implement them, when we get aware about.

Please get in contact with us about your special needs.

Our Technology

Siliconally provides wired connectivity technology for SoC integration. Our first technologies are IEEE 100BASE-T1 and 1000BASE-T1 Automotive Ethernet PHYs. We develop according to ISO 26262 with target ASIL B and AEC-Q100 Grade 1.

We plan tu support IEEE 10BASE-T1L and IEEE 2,5/5/10GBASE-T1 communication standards in near future and are evaluating IEEE 10BASE-T1S and MIPI communication standards for our future portfolio.

We develop in Automotive certified GLOBALFOUNDRIES® 22FDX technology but also support other technology nodes on demand. Our solutions are supported by the Racyics® Adaptive Body Bias (ABB) IP Platform.
