New Eagle OpenECU NX3 Controller
)
The NX3 is the industry's first single ECU solution combining Megawatt Charging System (MCS) and Combined Charging System (CCS) protocols with full vehicle supervisory control, covering powertrain, charging, and auxiliary system management. Commercial EV programs running MCS alongside CCS and a separate vehicle supervisory controller have traditionally required multiple ECUs, each carrying its own integration and validation overhead. More controllers means more wiring, more failure points, and more development cycles. By consolidating vehicle supervisory control, CCS charging, and MCS charging into a single controller, OEMs can reduce controller count, harness complexity, integration effort, validation time, and overall system cost while accelerating vehicle development.
Processor & hardware
Built on the Infineon Aurix TC387 microcontroller running at 300 MHz, with up to 8.5 MB code space, 800 KB RAM, and 254 KB calibration space. 80 pins with highly configurable I/O. Weight: 2.25 kg (4.96 lb).
I/O capabilities Up to 6 CAN-FD buses, 2 LIN buses (master and slave modes), up to 4 SENT inputs, up to 6 speed sensor inputs, up to 18 analog/digital inputs, 4 temperature sensor inputs, 13 low-side outputs, 9 high-side outputs, up to 4 H-bridge outputs with current and voltage feedback, 3 LED outputs, and a speedometer output. Alternative pin populations available from New Eagle for further customisation.
Off-the-shelf configurations
Three configurations are available: the full VCU+EVCC combining supervisory control with CCS and MCS charging; a standalone VCU for supervisory control without charging; and a standalone EVCC for charging control. All three include Over-the-Air (OTA) firmware update capability and ISO 21434 cybersecurity with integrated HSM.
Charging
Native support for J1772 (CCS) and Megawatt Charging (MCS). CCS includes Control Pilot, Proximity Pilot, CP Shield, and Power Line Communication (PLC) via the Qualcomm QCA7005 chipset. MCS includes insertion detection, charge enable, and Ethernet 10Base-T1S communication. Supported protocols: DIN SPEC 70121:2014-12, ISO 15118-2:2014, and ISO 15118-20 DIS.
Communication
CAN-FD (up to 6 buses, J1939 and UDS compatible), LIN (up to 2 buses), SENT (up to 4 channels), Ethernet (10Base-T1S). Flexible wake sources: ignition, CAN message, charge plug insertion, and programmable wake timer. Wake-on-CAN supported on CAN buses A and B.
Software development
Application software can be developed in MATLAB Simulink using the OpenECU blockset, or in C using the OpenECU C-API. The NX3 is integrated with New Eagle's Raptor® toolchain, enabling seamless development from model-based design through production deployment. Model-based control strategy libraries are available to accelerate development. Compatible with ATI Vision and Vector CANape calibration tools via CCP.
Functional safety & cybersecurity
Designed to meet ISO 26262 up to ASIL-D. Cybersecurity developed in accordance with ISO 21434, with an integrated HSM supporting Secure Boot, code signing, secure firmware update, secure keystore, security access, and secure logging, covering UN R155 and R156 requirements.
Applications
The NX3 is suited for light vehicles, agriculture, construction, mining and commercial vehicles, and off-highway machinery in ICE, hybrid, and full-electric architectures. Its single ECU approach is particularly relevant for platforms where reducing controller count, simplifying harness complexity, and meeting evolving dual-charging standards (MCS + CCS) are critical programme constraints.

renco integration support
renco is a Cologne-based EV system integrator and authorised New Eagle OpenECU Value-Added Reseller. Beyond hardware supply, we bring the engineering depth to deploy the NX3 effectively in your application.
The NX3's ISO 26262 ASIL-D and ISO 21434 cybersecurity architecture maps directly to renco's own software development capabilities. We develop VCU software to the same standards, with ASPICE-compliant processes covering functional safety architecture, SecOC, HSM key management, and intrusion detection. For teams integrating the NX3 into a new platform, or navigating functional safety and cybersecurity requirements for the first time, renco also provides tailored engineering support, helping you understand what compliance means in practice and how to build it in from the start.
