Product details
Overview
S32K328GHT1MPCSR 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 and domain controllers in harsh automotive environments.
For engineers reviewing the S32K328GHT1MPCSR datasheet, S32K328GHT1MPCSR pinout, S32K328GHT1MPCSR application, or S32K328GHT1MPCSR equivalent, key selection criteria include dual-core lockstep readiness, 1 Gbps Ethernet AVB/TSN support, CAN FD across eight FlexCAN modules, and functional safety compliance per ISO 26262 ASIL-B.
Technical Context
The S32K328GHT1MPCSR implements two independent Arm Cortex-M7 cores at 240 MHz each, each with single-precision FPU, DSP extension, and separate I/D caches. Its memory subsystem includes ECC on all flash and SRAM, plus 192 KB tightly coupled memory (TCM) for deterministic low-latency execution of critical control loops.
Timing and communication are managed via three eMIOS modules (72 timer channels), BCTU for cross-triggering between ADCs and timers, and a comprehensive peripheral set including six LPSPI, two LPI2C, sixteen LPUART, eight FlexCAN (all CAN FD-capable), two SAI, and one 1 Gbps Ethernet MAC with AVB/TSN support.
