Product details
Overview
S32G378ASAK1VUCT from NXP Semiconductors is a high-performance vehicle network processor combining ASIL D safety, hardware security, and heterogeneous compute (dual Cortex-A53 + triple lockstep Cortex-M7) for central gateway and domain controller applications. It integrates 4x PFE-accelerated Ethernet MACs (including GMAC), 16x CAN FD channels via LLCE, FlexRay, LIN, PCIe Gen3, DDR3L/LPDDR4, and 8 MB system SRAM with ECC - deployed in automotive central compute nodes requiring real-time protocol translation and secure FOTA orchestration.
For engineers reviewing the S32G378ASAK1VUCT datasheet, S32G378ASAK1VUCT pinout, S32G378ASAK1VUCT application, or S32G378ASAK1VUCT equivalent, key selection criteria include its -40 °C to 105 °C operating range, 525 FC-PBGA package, dual-cluster Cortex-A53 @ 1 GHz / triple lockstep Cortex-M7 @ 400 MHz configuration, and integrated PFE firewall + HSE_H security subsystem - all validated for ISO 26262 ASIL D and EVITA Full compliance.
Technical Context
The S32G378ASAK1VUCT implements a NoC-based safe interconnect fabric linking two Cortex-A53 clusters (each dual-core, 512 KB L2 cache, GIC-500) and three lockstep Cortex-M7 cores (400 MHz, 64 KB D-TCM each). Its LLCE offloads legacy network processing (16x CAN FD, 4x LINFlexD, 1x FlexRay), while the Packet Forwarding Engine (PFE) delivers stateful inspection, classification, and IEEE 1588v2/AVB timestamping across four Ethernet interfaces.
Security is enforced via HSE_H cryptographic engine (AES/CMAC/RSA/ECC), XRDC memory isolation across 8 domains, Arm TrustZone®, OTFAD, and eFuses for life-cycle management. Safety architecture includes FCCU, MBIST/LBIST, dual-clock domain monitoring, and lockstep CPU clusters meeting ISO 26262 ASIL D requirements.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_CORE | Core power supply | 0.72–0.87 V supply for Cortex-A53/Cortex-M7 clusters; requires tight regulation (±25 mV) and controlled ramp rate (0.001–24 V/ms). |

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 | Same family superset; identical pinout, package, and core configuration - differs only in fuse-programmed feature enablement (e.g., full PFE, LLCE, SerDes lanes). | Supports identical central gateway and domain controller use cases; validated for same ASIL D and EVITA Full security levels. | Select S32G274A when full hardware feature set (e.g., all 4 SerDes lanes, full 16 CAN FD) is required; S32G378ASAK1VUCT is functionally identical but may have subset features fused off. |
| R-Car H3 | ARM Cortex-A57/A53 + Cortex-R7; no integrated LLCE or PFE; relies on software stacks for CAN/Ethernet offload and lacks ASIL D-certified safety islands. | Targeted at infotainment and IVI; not certified for safety-critical gateway or ADAS roles without extensive external safety hardware. | Choose R-Car H3 only for non-safety-constrained multimedia applications where external networking accelerators and safety monitors are acceptable. |
Compared with S32G274A, the S32G378ASAK1VUCT offers identical silicon and packaging but may ship with certain features disabled via eFuses - enabling cost-optimized variants within the same qualification baseline.
