Product details
Overview
S32K312NHT0MPASR from NXP Semiconductors is an ASIL-B certified automotive microcontroller featuring a single Arm Cortex-M7 core operating up to 120 MHz, 2 MB program flash with ECC, 256 KB SRAM with ECC (including 96 KB TCM), and support for CAN FD, LPUART, LPSPI, and eMIOS timer subsystems. It targets body control modules, gateway ECUs, and battery management systems in harsh-temperature automotive environments.
For engineers reviewing the S32K312NHT0MPASR datasheet, S32K312NHT0MPASR pinout, S32K312NHT0MPASR application, or S32K312NHT0MPASR equivalent, key selection criteria include its 120 MHz M7 performance, -40 °C to 125 °C ambient operation, 2 MB flash/ECC memory architecture, and FlexCAN modules with CAN FD capability - all validated for ASIL-B functional safety compliance.
Technical Context
The S32K312NHT0MPASR implements a single-core Arm Cortex-M7 CPU with DSP extension and single-precision FPU, executing at up to 120 MHz with zero-wait I/D-TCM and cache support. Its memory subsystem includes ECC-protected 2 MB flash and 256 KB SRAM (96 KB TCM), enabling deterministic real-time control loops.
It integrates three 12-bit ADCs (24-channel each), two eMIOS modules (24 channels each), BCTU for cross-triggering, and dual LPI2C/LPSPI interfaces with DMA. Power management uses PMC-controlled RUN/STANDBY modes with peripheral clock gating, while security relies on HSE_B, XRDC, and CRC/EDC/ECC across memory and data paths.
