Product details
Overview
S32K310NHT0MLFSR from NXP Semiconductors is an ASIL-B automotive-qualified Arm® Cortex-M7 microcontroller operating at up to 120 MHz, featuring 512 KB program flash with ECC, 112 KB SRAM with ECC (including 96 KB TCM), and support for -40 °C to 125 °C ambient operation across all power modes. It integrates dual 24-channel 12-bit ADCs, three FlexCAN modules with CAN FD capability, and a full suite of safety mechanisms including ECC on all memories, SWT timers, and XRDC-based access control - deployed in body control modules and electric power steering systems.
For engineers reviewing the S32K310NHT0MLFSR datasheet, S32K310NHT0MLFSR pinout, S32K310NHT0MLFSR application, or S32K310NHT0MLFSR equivalent, this page delivers verified specifications, package mapping to MAPBGA257, validated pin functions, real-world automotive use cases, and two confirmed alternative parts with documented functional and integration differences.
Technical Context
The S32K310NHT0MLFSR implements a single-core Arm Cortex-M7 CPU executing at up to 120 MHz with Thumb®-2 ISA, integrated DSP extension, single-precision FPU, and configurable NVIC. Its memory subsystem includes I/D cache, zero-wait TCM RAM, and RWW-capable flash supporting A/B swap for OTA updates.
Timing architecture combines FXOSC (8–40 MHz), FIRC (48 MHz), SIRC (32 kHz), SXOSC (32 kHz), and SPLL for flexible clock domain management. Safety-critical peripherals - eMIOS timers, BCTU, LCU, and STM - are synchronized via TRGMUX and support cross-triggering with ADCs for deterministic control loop execution.
