Product details
Overview
S32K348GHT1MPCSR from NXP Semiconductors is an ASIL-D certified automotive MCU featuring dual Arm Cortex-M7 cores in lockstep configuration, 8 MB ECC-protected program flash, 1152 KB SRAM with 192 KB TCM, and operation across -40 °C to 125 °C ambient temperature. It integrates 8 FlexCAN modules with CAN FD support, 1 Gbps Ethernet (AVB/TSN), and QuadSPI interface up to 2 Gbps for real-time body control and domain controller applications.
For engineers reviewing the S32K348GHT1MPCSR datasheet, S32K348GHT1MPCSR pinout, S32K348GHT1MPCSR application, or S32K348GHT1MPCSR equivalent, key selection criteria include ASIL-D functional safety compliance, lockstep core architecture for fault detection, 8 MB flash with RWW/A/B swap for OTA updates, and integrated hardware security engine (HSE-B) supporting AES-256, RSA-4096, and ECC-521.
Technical Context
The S32K348GHT1MPCSR implements a dual-core lockstep Arm Cortex-M7 platform running at 240 MHz per core, with separate I/D caches and zero-wait-state TCM to ensure deterministic execution for safety-critical control loops. Its memory subsystem includes ECC on all on-chip memories and EDC on data paths, backed by centralized error detection via FCCU and CMU.
Timing and communication are tightly coupled through BCTU cross-triggering between ADCs and timers, TRGMUX for signal routing, and XRDC-based access control enforcing master-domain isolation. The device supports full ISO 26262 ASIL-D compliance with hardware redundancy, MBIST/LBIST, voltage/clock monitoring, and virtualization wrapper (VIRT_WRAPPER) for I/O protection.
