Product details
Overview
S32K338GHT1VPCST from NXP Semiconductors is an ASIL-B certified automotive MCU featuring three independent Arm Cortex-M7 cores running at 240 MHz, 8 MB ECC-protected program flash, 1152 KB SRAM with 384 KB TCM, and integrated QuadSPI supporting up to 2 Gbps (8-bit data width). It delivers deterministic real-time control for body electronics and domain controllers in harsh automotive environments.
For engineers reviewing the S32K338GHT1VPCST datasheet, S32K338GHT1VPCST pinout, S32K338GHT1VPCST application, or S32K338GHT1VPCST equivalent, key selection criteria include triple-core lockstep readiness, CAN FD support across 8 FlexCAN modules, Ethernet AVB/TSN compliance, and hardware security engine (HSE_B) integration for secure boot and cryptographic acceleration.
Technical Context
The S32K338GHT1VPCST implements a scalable multi-core architecture with three independent Arm Cortex-M7 cores-each with FPU, DSP, I/D-cache, and zero-wait TCM-coordinated via a 64-bit crossbar fabric. Its memory subsystem includes ECC on all SRAM and flash, plus RWW A/B swap for OTA updates.
Timing and safety are enforced through dual PLLs, System Timer Modules (STM), BCTU for ADC/timer cross-triggering, and functional safety peripherals including FCCU, SWT, CMU, and XRDC-based access control-all compliant with ISO 26262 ASIL-B requirements.
