Product details
Overview
S32K328NHT1VPCST 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), and integrated QuadSPI supporting up to 2 Gbps with 8-bit data width. It delivers real-time control for body electronics, gateway modules, and domain controllers in harsh automotive environments.
For engineers reviewing the S32K328NHT1VPCST datasheet, S32K328NHT1VPCST pinout, S32K328NHT1VPCST application, or S32K328NHT1VPCST equivalent, key selection criteria include dual-core lockstep readiness, 1 Gbps Ethernet AVB/TSN support, CAN FD channel count (8), safety compliance level (ASIL-B), and package-specific thermal performance in MAPBGA437.
Technical Context
The S32K328NHT1VPCST implements two independent Arm Cortex-M7 cores at 240 MHz with separate I/D caches and FPU/DSP extensions, enabling deterministic real-time execution and parallel task partitioning. Its memory subsystem includes ECC on all SRAM and flash, plus a dedicated 192 KB TCM for latency-critical control loops.
Timing architecture integrates three eMIOS modules (72 timer channels), BCTU for ADC/timer cross-triggering, and TRGMUX for flexible event routing-supporting precise sensor synchronization and motor control timing. Safety is enforced via FCCU, SWT timers, CRC, and XRDC-based access protection across memory and peripherals.

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, and peripheral set but with redundant core execution and enhanced safety mechanisms | Required for ASIL-D safety goals (e.g., brake-by-wire); adds diagnostic coverage but increases power and cost | Select S32K344 when full ASIL-D compliance is mandated; S32K328NHT1VPCST suffices for ASIL-B systems with lower safety overhead |
| S32K324 | ASIL-B dual-core variant with 4 MB flash, 512 KB SRAM, and no 1 Gbps Ethernet-supports only 100 Mbps AVB/TSN and 4 FlexCAN channels | Suitable for mid-tier gateways or body controllers where bandwidth and channel count are constrained | Choose S32K324 for cost-optimized designs with reduced memory and connectivity needs; S32K328NHT1VPCST enables future scalability without PCB redesign |
Compared with S32K344, S32K328NHT1VPCST reduces safety certification burden while retaining dual-core performance and full peripheral feature set; versus S32K324, it doubles flash capacity and adds 1 Gbps Ethernet and 4 additional CAN FD channels-enabling higher integration in next-generation vehicle domains.
