Product details
Overview
S32K324NHT1MPBIR from NXP Semiconductors is an ASIL-B dual-core Arm® Cortex-M7 automotive MCU operating up to 160 MHz, featuring 4 MB program flash with ECC, 512 KB SRAM with ECC (including 192 KB TCM), and support for CAN FD, Ethernet AVB/TSN, and QuadSPI up to 480 Mbps. It targets body control modules, gateway ECUs, and chassis domain controllers in harsh-temperature automotive environments.
For engineers reviewing the S32K324NHT1MPBIR datasheet, S32K324NHT1MPBIR pinout, S32K324NHT1MPBIR application, or S32K324NHT1MPBIR equivalent, key selection criteria include dual-core real-time determinism, ASIL-B safety compliance, integrated FlexCAN (6 channels, all CAN FD-capable), and MAPBGA437 package compatibility with automotive PCB layout constraints.
Technical Context
The S32K324NHT1MPBIR implements two independent Arm Cortex-M7 cores at 160 MHz each, each with single-precision FPU, DSP extension, and separate I/D caches-enabling parallel task execution while maintaining deterministic latency for motor control and communication stacks. Its memory subsystem includes 4 MB on-chip flash with ECC, 512 KB SRAM with ECC (192 KB tightly coupled), and QuadSPI interface supporting external memory expansion at 480 Mbps with 4-bit data width.
Peripherals are architected for automotive domain consolidation: six FlexCAN modules (all CAN FD), sixteen LPUARTs (LIN-capable), six LPSPIs, two LPI2Cs, two SAI audio interfaces, and three 12-bit ADCs (24-channel each) with BCTU cross-triggering. Safety is enforced via FCCU, SWT timers, ECC/EDC across all memories and data paths, and XRDC-based access control.
