Product details
Overview
S32K322EHT0MPBST from NXP Semiconductors is an ASIL-B dual-core Arm Cortex-M7 automotive MCU operating up to 160 MHz, featuring 2 MB program flash with ECC, 256 KB SRAM (including 192 KB TCM), and dual FlexCAN modules with CAN FD support-designed for body control modules in electric powertrain gateways.
For engineers reviewing the S32K322EHT0MPBST datasheet, S32K322EHT0MPBST pinout, S32K322EHT0MPBST application, or S32K322EHT0MPBST equivalent, key selection criteria include dual-core real-time determinism, 160 MHz M7 performance with TCM latency optimization, ASIL-B safety certification, QuadSPI interface for external memory expansion, and Ethernet (100 Mbps AVB/TSN) + CAN FD connectivity for domain controller architectures.
Technical Context
The S32K322EHT0MPBST implements two independent Arm Cortex-M7 cores at 160 MHz with separate I/D caches and 192 KB tightly coupled memory (TCM), enabling deterministic execution of safety-critical and application tasks in parallel. It integrates a 64-bit crossbar switch fabric, dual eMIOS timer modules (48 channels total), and BCTU for synchronized ADC/timer triggering.
Its safety architecture includes hardware error detection on all memories (ECC), centralized fault collection (FCCU), dual SWT timers, and XRDC-based access control-meeting ISO 26262 ASIL-B requirements without lockstep redundancy. Power management supports RUN and STANDBY modes with peripheral-specific clock gating.
