Product details
Overview
S32K328GHT1VJBSR from NXP Semiconductors is an ASIL-B dual-core Arm Cortex-M7 automotive MCU operating up to 240 MHz, featuring 8 MB ECC-protected program flash, 1152 KB SRAM (including 192 KB TCM), triple 12-bit ADCs (24-channel each), eight FlexCAN modules with CAN FD support, and dual 100/1000 Mbps Ethernet with AVB/TSN. It targets body control modules and domain controllers in electric vehicle powertrain gateways.
For engineers reviewing the S32K328GHT1VJBSR datasheet, S32K328GHT1VJBSR pinout, S32K328GHT1VJBSR application, or S32K328GHT1VJBSR equivalent, key selection criteria include dual-core real-time determinism, ASIL-B safety compliance, QuadSPI interface supporting up to 2 Gbps (8-bit), uSDHC host controller, and 32-channel DMAMUX for peripheral offloading in harsh automotive environments.
Technical Context
The S32K328GHT1VJBSR implements two independent Arm Cortex-M7 cores at 240 MHz with separate I/D caches, FPU, and DSP extensions, coordinated via a 64-bit crossbar fabric. Its memory subsystem includes ECC on all SRAM and flash, plus TCM RAM optimized for low-latency control loops.
Timing and safety are enforced by integrated modules: BCTU for cross-triggering ADC/timer events, XRDC for master access protection, HSE_B for AES/RSA/ECC acceleration, and dual SWT watchdogs. Power management uses PMC with RUN/STANDBY modes and per-peripheral clock gating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K344 | ASIL-D lockstep dual-core variant; identical 8 MB flash, 1152 KB SRAM, but adds redundant core checking and enhanced error containment | Required for ASIL-D safety goals (e.g., steering actuation); higher FIT rate and stricter qualification testing | Select S32K344 when functional safety architecture mandates lockstep execution and diagnostic coverage >99% |
| S32K324 | ASIL-B dual-core variant with 4 MB flash, 512 KB SRAM, no uSDHC or 1 Gbps Ethernet; same 240 MHz M7 cores and peripheral set minus advanced networking | Suitable for mid-tier body domain controllers where cost sensitivity outweighs need for OTA or gigabit bandwidth | Choose S32K324 for non-gateway applications requiring dual-core performance but lower memory and interface count |
Compared with S32K328GHT1VJBSR, S32K344 provides certified ASIL-D fault containment at higher cost and power, while S32K324 offers reduced memory and interface capability for cost-constrained body electronics-neither is pin-compatible, requiring PCB redesign for migration.
