Product details
Overview
S32K328GHT1MJBST from NXP Semiconductors is an ASIL-B dual-core Arm® Cortex-M7 automotive microcontroller 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 and domain controllers in harsh automotive environments.
For engineers reviewing the S32K328GHT1MJBST datasheet, S32K328GHT1MJBST pinout, S32K328GHT1MJBST application, or S32K328GHT1MJBST equivalent, key selection factors include dual-core deterministic timing, CAN FD support across eight FlexCAN modules, Ethernet AVB/TSN at 1 Gbps, and hardware security engine (HSE_B) with AES acceleration - all validated for -40 °C to 125 °C operation.
Technical Context
The S32K328GHT1MJBST implements two independent Arm Cortex-M7 cores running at 240 MHz each, with separate I/D caches and zero-wait-state TCM RAM to minimize latency in fast control loops. Its memory subsystem includes ECC on all SRAM and flash, plus RWW (Read-While-Write) capability enabling A/B swap for OTA updates.
Timing and safety are enforced via dual PLLs, System Timer Modules (STM), three eMIOS blocks (72 timer channels total), and a centralized Functional Safety Control Unit (FCCU) with ASIL-B compliance. The device integrates BCTU for cross-triggering between ADCs and timers, and XRDC for master-access rights protection across domains.
