Product details
Overview
S32K342NHT0MPBST from NXP Semiconductors is an ASIL-D-certified, lockstep dual-core Arm Cortex-M7 microcontroller designed for automotive safety-critical applications. It operates at up to 160 MHz, integrates 2 MB ECC-protected program flash and 256 KB ECC SRAM (including 192 KB TCM), supports CAN FD across four FlexCAN modules, and delivers real-time control in harsh environments with -40 °C to 125 °C operation.
For engineers reviewing the S32K342NHT0MPBST datasheet, S32K342NHT0MPBST pinout, S32K342NHT0MPBST application, or S32K342NHT0MPBST equivalent, this page provides verified specifications, package mapping, functional safety architecture details, and validated alternative options for automotive body control, chassis domain controllers, and ASIL-D-compliant gateway designs.
Technical Context
The S32K342NHT0MPBST implements a lockstep dual Arm Cortex-M7 core configuration with hardware redundancy, enabling ASIL-D compliance per ISO 26262. It includes integrated Safety Management Unit (FCCU), memory ECC on all SRAM/flash, and centralized error detection via CMU and EIM/ERM modules.
Its timing subsystem combines three eMIOS modules (72 timer channels), BCTU for cross-triggering between ADC and timers, and TRGMUX for flexible event routing-enabling deterministic motor control and sensor fusion without CPU intervention.
