The NOVOSENSE NCA1044-Q1 is an automotive CAN FD transceiver. NOVOSENSE says it passed Toyota’s VeLIO vehicle-network certification after receiving EMC certification from IBEE/FTZ-Zwickau. Those claims provide evidence about network interoperability and electromagnetic compatibility, but do not establish acceptance for every vehicle platform or design.
What the Toyota VeLIO claim covers
NOVOSENSE describes VeLIO as Toyota’s Vehicle LAN Interoperability and Optimization program. The company’s announcement says the NCA1044-Q1 passed its certification. The listed evaluation areas include transceiver delay, dV/dt, distortion-delay, threshold-voltage response, single-ended S-parameters and static tests.
In its announcement, NOVOSENSE Microelectronics wrote: “NOVOSENSE proudly announces that the NCA1044-Q1, our automotive-grade CAN FD transceiver, has officially passed Toyota’s VeLIO (Vehicle LAN Interoperability and Optimization) certification.” This is the company’s statement about the product’s result; it should not be read as a blanket approval for every Toyota vehicle, network topology or system design.

What the European EMC validation means
The cited product announcement says the device meets IBEE/FTZ-Zwickau requirements aligned with IEC 62228-3, and also references Volkswagen’s VW80121-3, 2023-12 EMC requirements. These are EMC-related validations, distinct from VeLIO’s vehicle-network interoperability and optimization assessment.

Published electrical and protection specifications
NOVOSENSE’s 2024 Product Selection Guide and 2025 NCA1044-Q1 datasheet publish the following figures. Check the datasheet revision and exact orderable part number before using any value in a design.

The 2025 datasheet also lists ISO 7637-2 transient-test parameters. The cited material does not provide the parameter values here, so the datasheet’s test conditions and limits should be checked directly rather than inferring transient immunity from the standard’s name.
Rank #2
- Optimized for robust performance in challenging interference conditions.
- Capable of reliable data transmission at varying speeds.
- Compliant with the ISO11898 standard for seamless integration.
- Features high input impedance to support up to 120 nodes.
- Operates in a low-power standby mode with a typical current draw of 370μA.
Packages, applications and part-number checks
The 2024 selection guide lists SOP8 and DFN8 package variants and identifies automotive gateways, body-control modules, ADAS, infotainment and heavily loaded CAN networks as applications. These are stated application areas, not evidence that one package or configuration is suitable for every board or vehicle.
The datasheet distinguishes orderable part numbers described as VeLIO verified from part numbers described as potentially able to pass VeLIO testing. Confirm the complete suffix and its status in the current documentation; do not assume that all package variants have identical certification evidence.
Rank #3
- 1. Optimized for robust performance in challenging interference conditions.
- 2. Capable of reliable data transmission at varying speeds.
- 3. Compliant with the ISO11898 standard for seamless integration.

- 5. Operates in a low-power standby mode with a typical current draw of 370μA.
How to assess the NCA1044-Q1 for a design
- Match the network requirements. Confirm that the application’s CAN FD rate, bus-fault exposure, common-mode conditions and logic-supply voltage fit the published values and your system’s operating margins.
- Verify qualification and validation scope. Obtain current qualification documents and EMC test conditions, and confirm that the exact part number has the certification status required by the OEM.
- Check implementation details. Review the current datasheet for standby and wake behavior, thermal operating range, pinout, package footprint and any board-level EMC requirements. These details should not be inferred from the certification announcement.
- Compare alternatives by exact datasheet. The 2024 NOVOSENSE guide names NXP TJA1044/TJA1057 and TI TCAN1044A/TCAN1057A as functional or pin-to-pin market analogues. Those descriptions do not guarantee drop-in equivalence: check pin compatibility, operating behavior, ratings, qualification and package for the exact models being considered.
Production and availability
NOVOSENSE and the cited industry announcement describe the NCA1044-Q1 as in mass production and shipping to OEM and Tier-1 customers. That is a company or industry-publication claim, not a guarantee of current stock from a particular distributor. For procurement, confirm live availability, package suffix and minimum order quantity with the seller.
