Product details
Overview
S32K328GHT1VJBST 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 deterministic real-time control for body electronics, domain controllers, and gateway modules in harsh automotive environments.
For engineers reviewing the S32K328GHT1VJBST datasheet, S32K328GHT1VJBST pinout, S32K328GHT1VJBST application, or S32K328GHT1VJBST equivalent, key selection criteria include dual-core lockstep readiness, 1 Gbps Ethernet AVB/TSN support, CAN FD channel count (8), safety compliance (ASIL-B), and thermal operation range (−40 °C to 125 °C).
Technical Context
The S32K328GHT1VJBST implements two independent Arm Cortex-M7 cores at 240 MHz with separate I/D caches and TCM RAM, enabling parallel task execution while maintaining low-latency interrupt response. Its memory subsystem includes ECC on all SRAM and flash, plus a dedicated BCTU for cross-triggering ADC and timer events.
It integrates a full automotive communication stack: eight FlexCAN modules with CAN FD, sixteen LPUARTs, six LPSPIs, two LPI2Cs, two SAI audio interfaces, and a 1 Gbps Ethernet MAC with AVB/TSN support - all backed by DMAMUX-driven 32-channel DMA for zero-CPU-overhead data movement.

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 Cortex-M7 @ 160 MHz; 4 MB flash; no Ethernet or QuadSPI | Targeted at safety-critical steering/braking where lockstep redundancy is mandatory, but bandwidth requirements are lower | Select S32K344 when ISO 26262 ASIL-D certification is required and 1 Gbps Ethernet or external memory expansion is unnecessary |
| S32K358 | ASIL-D triple-core Cortex-M7 @ 240 MHz; 8 MB flash; adds uSDHC interface; same package options | Designed for higher-integration ADAS domain controllers requiring local storage and enhanced compute partitioning | Choose S32K358 if uSDHC-based log storage or third core for isolated safety monitor is needed - otherwise S32K328GHT1VJBST offers optimal cost/performance balance |
Compared with S32K344 and S32K358, the S32K328GHT1VJBST uniquely balances ASIL-B dual-core performance, 1 Gbps Ethernet, QuadSPI expansion, and thermal ruggedness - making it ideal for scalable gateway and domain controller designs where ASIL-D is not mandated but bandwidth and flexibility are critical.
