Product details
Overview
S32K341NHT0VPASR from NXP Semiconductors is an ASIL-D-certified, lockstep dual-core Arm Cortex-M7 microcontroller designed for automotive safety-critical control units. It operates at up to 160 MHz, integrates 1 MB ECC-protected program flash and 256 KB ECC SRAM (including 192 KB TCM), and supports CAN FD, Ethernet AVB/TSN, and QuadSPI for external memory expansion - deployed in battery management systems and chassis domain controllers.
For engineers reviewing the S32K341NHT0VPASR datasheet, S32K341NHT0VPASR pinout, S32K341NHT0VPASR application, or S32K341NHT0VPASR equivalent, key selection criteria include ASIL-D functional safety compliance, lockstep core redundancy, 160 MHz real-time performance with zero-wait TCM, and integrated hardware security engine (HSE-B) supporting AES-256 acceleration.
Technical Context
The S32K341NHT0VPASR implements a lockstep pair of Arm Cortex-M7 cores executing identical instructions with hardware comparison logic to detect divergence, satisfying ISO 26262 ASIL-D requirements. Its memory subsystem includes ECC on all on-chip flash and SRAM, plus CRC and EDC protection across data paths.
Timing and communication are tightly coupled via BCTU cross-triggering between ADCs and timers, TRGMUX for event routing, and dedicated FlexCAN modules with full CAN FD support - enabling deterministic sensor fusion and actuator control in electric powertrain applications.
