Product details
Overview
S32G399ASCK1VUCR from NXP Semiconductors is a high-performance automotive vehicle network processor integrating dual Cortex-A53 application cores (1 GHz), three lockstep Cortex-M7 real-time cores (400 MHz), ASIL D functional safety infrastructure, hardware security engine (HSE_H), and network acceleration for Ethernet (PFE), CAN FD, FlexRay, and LIN. It delivers 8 MB system SRAM with ECC, LPDDR4/DDR3L memory interface, and PCIe Gen3 SerDes for central gateway and domain controller applications in EVs and ADAS systems.
For engineers reviewing the S32G399ASCK1VUCR datasheet, S32G399ASCK1VUCR pinout, S32G399ASCK1VUCR application, or S32G399ASCK1VUCR equivalent, key selection criteria include its dual-cluster A53/M7 compute architecture, integrated PFE firewall and classification engine, 525 FC-PBGA package with 0.8 mm pitch, and support for -40 °C to 105 °C ambient operation under AEC-Q100 qualification.
Technical Context
The S32G399ASCK1VUCR implements a heterogeneous multi-core architecture with two independent Cortex-A53 clusters (dual-core each) and three lockstep Cortex-M7 cores, all interconnected via a NoC-safe interconnect fabric. Its LLCE (Legacy Link Controller Engine) offloads transport-layer processing for up to 16 BCAN, 1 FlexRay (dual-channel), and 4 LINFlexD interfaces.
Network acceleration is provided by the Packet Forwarding Engine (PFE) supporting IEEE 1588v2 timestamping, stateful inspection firewall, header manipulation, and up to four Ethernet MACs (3× PFE_MAC + 1× GMAC_0) with MII/RMII/RGMII/SGMII PHY support. The chip includes HSE_H for symmetric/asymmetric crypto, XRDC-based resource isolation across 8 domains, and Arm TrustZone for secure execution environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar vehicle network processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32G274A | Superset variant with identical package, pinout, and core configuration; includes full PFE, LLCE, and SerDes feature set enabled. | Supports maximum Ethernet port count (4 MACs) and full PCIe Gen3 bandwidth; suitable for premium gateway designs requiring full feature headroom. | Select S32G274A when full PFE rule table depth, LLCE channel count, or PCIe lane flexibility is required; S32G399ASCK1VUCR is functionally identical but may have factory-configured feature gating. |
| R-Car H3 | 6× Cortex-A57/A53 cores, no lockstep M7, no integrated HSE_H, no LLCE offload; relies on software stacks for CAN/FlexRay. | Targeted at IVI and infotainment; lacks ASIL-D safety certification path and hardware-accelerated legacy bus handling. | Choose R-Car H3 only for non-safety-critical multimedia gateways where Linux ecosystem breadth outweighs real-time determinism and functional safety needs. |
Compared with S32G274A, the S32G399ASCK1VUCR offers identical silicon and pin compatibility but may reflect a specific mask revision or feature-binned configuration; compared with R-Car H3, it provides hardware-enforced safety, security, and legacy network offload essential for production automotive gateways.
