Product details
Overview
S32K328GHT1VPCSR from NXP Semiconductors is an ASIL-B dual-core Arm® Cortex-M7 automotive MCU operating up to 240 MHz, featuring 8 MB ECC-protected program flash, 1152 KB SRAM (including 192 KB TCM), and integrated QuadSPI supporting up to 2 Gbps with 8-bit data width. It delivers real-time control for body electronics, gateway modules, and domain controllers in harsh automotive environments.
For engineers reviewing the S32K328GHT1VPCSR datasheet, S32K328GHT1VPCSR pinout, S32K328GHT1VPCSR application, or S32K328GHT1VPCSR equivalent, key selection criteria include dual-core deterministic timing, CAN FD support across eight FlexCAN modules, 1 Gbps Ethernet with AVB/TSN, and functional safety compliance per ISO 26262 ASIL-B.
Technical Context
The S32K328GHT1VPCSR implements two independent Arm Cortex-M7 cores running at 240 MHz each, with separate I/D caches, FPU, DSP extensions, and zero-wait-state TCM RAM to minimize latency in motor control and safety-critical loops. Its memory subsystem includes ECC on all flash and SRAM, plus RWW (Read-While-Write) capability enabling A/B swap for OTA updates.
Timing and communication are tightly coordinated via BCTU for cross-triggering between ADCs and timers, TRGMUX for signal routing, and a distributed DMA architecture with DMAMUX supporting 32 channels and 128 request sources. Safety is enforced by FCCU, SWT, CRC, XRDC, and VIRT_WRAPPER for hardware-enforced access isolation.
