NXP Semiconductors Introduces 48 V Zonal Reference System

Integrated zonal platform simplifies software-defined vehicle development
Automotive electronic architectures are evolving toward software-defined vehicles (SDVs) that rely on centralized computing and zonal electronic control units (ECUs) to manage both energy and data across the vehicle. NXP Semiconductors has introduced the CoreRide Z248 zonal reference system, a design-ready hardware-software foundation that integrates 48 V energy distribution, deterministic networking, and real-time processing for next-generation automotive E/E architectures.

The system is intended to help automotive OEMs and Tier-1 suppliers accelerate development of scalable zonal vehicle architectures by providing a validated reference platform that reduces integration complexity while supporting advanced vehicle functions such as intelligent power management, AI-enabled sensing, and consolidated ECU processing.

48 V architecture integrates energy distribution and data routing
The CoreRide Z248 reference system combines 48 V power distribution and intelligent data routing within a unified architecture. This approach addresses the growing complexity of modern vehicle electronics, where multiple ECUs must simultaneously manage power delivery, communication networks, and safety-critical functions.

The platform is designed to support smart data energy network (SDEN) functionality, including impedance monitoring, power protection, diagnostics, audio processing, and AI-enabled virtual sensing. By integrating these functions into a pre-validated system, developers can reduce the engineering effort required to build complex zonal ECUs from separate hardware and software components.

The architecture also supports ECU consolidation and integration of end-node functions, enabling vehicle designers to reduce the number of control units while maintaining system performance and reliability.

S32K5 microcontroller with MRAM enables faster OTA updates
At the core of the reference system is NXP’s S32K566 microcontroller, part of the S32K5 series, which integrates embedded MRAM memory. This technology enables significantly faster programming times during vehicle manufacturing and supports frequent over-the-air (OTA) software updates throughout the vehicle lifecycle.

The Z248 platform also integrates networking and power management components required for zonal ECUs, including Ethernet PHY interfaces, CAN transceivers, eFuse protection devices, power management ICs (PMICs), and DC-DC converters. These components allow the system to manage energy conversion, protection, and distribution within the same architecture used for vehicle communication and processing.

Pre-validated software stack supports functional safety and real-time operation
To reduce software integration challenges, the system includes a pre-validated software stack developed in collaboration with partners in the CoreRide ecosystem. The platform integrates tools and software components from several automotive software providers, including:

The reference system includes a Board Support Package (BSP) and validated development environment supporting continuous integration, testing, and deployment (CI/CT/CD) workflows. This environment allows OEMs and Tier-1 suppliers to run faster validation cycles while maintaining system reliability and functional safety requirements.

System-level validation has been performed through thousands of tests, demonstrating low-power operation, fast boot times, and rapid wake-up response—capabilities required for automotive ECUs operating within zonal architectures.

Supporting zonal architectures across ICE, hybrid, and electric vehicles
The CoreRide Z248 reference system is designed to support internal combustion engine (ICE), hybrid, and battery-electric vehicle platforms. Its scalable hardware and software stack can be adapted to different SDV architectures while maintaining compatibility with NXP’s broader automotive portfolio, including compute, networking, and power management technologies.

By integrating 48 V energy distribution with deterministic networking and processing in a single architecture, the system provides a platform for vehicle manufacturers transitioning from traditional distributed ECUs to zonal processing and centralized vehicle control systems.

The CoreRide Z248 zonal reference system is currently available to selected customers, accompanied by system documentation including safety manuals, validated performance indicators, and software integration guidance to support development of future vehicle programs.
