Product details
Overview
S32K324NHT1VMMST from NXP Semiconductors is an ASIL-B dual-core Arm® Cortex-M7 automotive MCU operating up to 160 MHz, featuring 4 MB program flash with ECC, 512 KB SRAM with ECC (including 192 KB TCM), and support for CAN FD, Ethernet AVB/TSN, and QuadSPI interface. It targets body control modules, gateway ECUs, and chassis domain controllers in harsh automotive environments.
For engineers reviewing the S32K324NHT1VMMST datasheet, S32K324NHT1VMMST pinout, S32K324NHT1VMMST application, or S32K324NHT1VMMST equivalent, key selection considerations include dual-core lockstep readiness, 160 MHz real-time performance, ASIL-B safety compliance, QuadSPI-enabled external memory expansion, and integrated hardware security engine (HSE_B) with AES acceleration.
Technical Context
The S32K324NHT1VMMST implements two independent Arm Cortex-M7 cores at 160 MHz each, with separate I/D caches and TCM RAM to minimize latency in fast control loops. It integrates a 64-bit crossbar switch fabric, DMAMUX-controlled 32-channel DMA, and BCTU for precise ADC/timer cross-triggering.
Its timing subsystem includes three eMIOS modules (72 timer channels), two STM modules, three PIT modules, and a 32-bit RTC with autonomous periodic interrupt capability. Safety architecture incorporates ECC on all memories, centralized error detection via FCCU, and XRDC-based access control for master domains.
