Product details
Overview
S32K311NHT0VLFST from NXP Semiconductors is an ASIL-B automotive-qualified Arm® Cortex-M7 microcontroller operating at up to 120 MHz, featuring 1 MB program flash with ECC, 128 KB SRAM with ECC (including 96 KB TCM), and support for CAN FD, LPUART, LPSPI, and LPI2C interfaces. It targets body control modules, gateway ECUs, and battery management systems in harsh automotive environments.
For engineers reviewing the S32K311NHT0VLFST datasheet, S32K311NHT0VLFST pinout, S32K311NHT0VLFST application, or S32K311NHT0VLFST equivalent, key selection criteria include its 120 MHz Cortex-M7 core with FPU/DSP, -40 °C to 125 °C ambient operation, 2.97–5.5 V supply range, integrated safety features (ECC, SWT, XRDC), and FlexCAN modules with CAN FD capability.
Technical Context
The S32K311NHT0VLFST implements a single-core Arm Cortex-M7 CPU executing the Armv7 and Thumb®-2 ISA, with a Single Precision Floating Point Unit and configurable NVIC. Its memory subsystem includes instruction/data caches and TCM RAM optimized for low-latency real-time control loops.
Timing architecture integrates FXOSC (8–40 MHz), FIRC (48 MHz), SIRC (32 kHz), SXOSC (32 kHz), and SPLL for flexible clock domain management. Peripheral clock gating via PMC enables selective power-down of non-critical modules during STANDBY mode while retaining wakeup-capable GPIO and RTC functionality.

FAQ
What is the maximum operating frequency of the S32K311NHT0VLFST?
The S32K311NHT0VLFST operates at up to 120 MHz using its Arm Cortex-M7 core. This frequency is achieved with the System PLL (SPLL) driven by the Fast External Oscillator (FXOSC) or Fast Internal RC oscillator (FIRC). The core maintains full performance across its specified -40 °C to 125 °C ambient temperature range, and the S32K311NHT0VLFST datasheet confirms this rating under all power modes.
Does the S32K311NHT0VLFST support CAN FD?
Yes, the S32K311NHT0VLFST integrates three FlexCAN modules, each fully supporting CAN FD with data rates up to 5 Mbps and payload lengths up to 64 bytes. CAN FD operation is enabled via hardware message filtering and bit-rate switching logic embedded in the FlexCAN peripheral, and the S32K311NHT0VLFST reference manual specifies full compliance with ISO 11898-1:2015.
What package type is used for the S32K311NHT0VLFST?
The S32K311NHT0VLFST uses the HDQFP100 package: a 100-pin heat sink exposed pad quad flat package with 0.5 mm pitch. This package is explicitly listed in the S32K3xx Data Sheet Rev. 14 for the S32K311 variant and supports thermal dissipation requirements for continuous operation at 120 MHz in automotive under-hood environments.
How much SRAM does the S32K311NHT0VLFST include, and what is its ECC coverage?
The S32K311NHT0VLFST includes 128 KB of SRAM, all protected by Error-Correcting Code (ECC). Of this, 96 KB is allocated as Tightly Coupled Memory (TCM) for ultra-low-latency CPU access, while the remaining 32 KB serves as general-purpose data SRAM. ECC coverage applies to both instruction and data SRAM regions, as confirmed in the S32K311NHT0VLFST memory map section of the reference manual.
Is the S32K311NHT0VLFST qualified for automotive ASIL-B applications?
Yes, the S32K311NHT0VLFST is certified to ASIL-B per ISO 26262:2018. Its safety features include dual watchdog timers (SWT), Fault Collection and Control Unit (FCCU), ECC on all memories, centralized error detection, and hardware memory protection unit (MPU). These capabilities are documented in the S32K311NHT0VLFST functional safety manual and supported by NXP's ASIL-B safety case.
