Product details
Overview
S32K322NHT0VPAST from NXP Semiconductors is an ASIL-B certified dual-core Arm® Cortex-M7 automotive microcontroller operating up to 160 MHz, featuring 2 MB program flash with ECC, 256 KB SRAM (including 192 KB TCM), and integrated QuadSPI interface supporting up to 480 Mbps for external memory expansion. It delivers real-time motor control subsystem offloading and supports Ethernet AVB/TSN, CAN FD, and LIN in harsh-automotive environments.
For engineers reviewing the S32K322NHT0VPAST datasheet, S32K322NHT0VPAST pinout, S32K322NHT0VPAST application, or S32K322NHT0VPAST equivalent, key selection considerations include dual-core lockstep readiness, ASIL-B functional safety compliance, QuadSPI bandwidth, TCM RAM allocation for latency-critical control loops, and FlexCAN channel count with CAN-FD support.
Technical Context
The S32K322NHT0VPAST implements two independent Arm Cortex-M7 cores at 160 MHz each, with separate I/D caches and zero-wait-state TCM RAM, enabling deterministic execution for safety-critical automotive control tasks. Its cross-triggering architecture tightly couples BCTU, eMIOS timers, and ADCs for synchronized sensor sampling and actuator timing.
Power management integrates a dedicated PMC with RUN/STANDBY modes and peripheral-specific clock gating, while security relies on HSE-B hardware acceleration for AES-256, RSA-4096, and ECC-521, plus XRDC-based access control and Virtualization Wrapper for I/O protection.
