It targets body control modules, gateway ECUs, and chassis domain controllers in harsh automotive environments.
For engineers reviewing the S32K314NHT1MMMST datasheet, S32K314NHT1MMMST pinout, S32K314NHT1MMMST application, or S32K314NHT1MMMST equivalent, key selection criteria include its 160 MHz Cortex-M7 core with FPU/DSP, ASIL-B safety certification, 4 MB on-chip flash with RWW and A/B swap for OTA updates, and integrated hardware security engine (HSE_B) supporting AES acceleration.
Technical Context
The S32K314NHT1MMMST implements a single Arm Cortex-M7 core executing at up to 160 MHz with Thumb-2 ISA, integrated Single Precision FPU and DSP extensions, and zero-wait-state I/D-TCM for deterministic real-time control. Its memory subsystem includes ECC-protected 4 MB program flash, 128 KB data flash, and 512 KB SRAM with 192 KB TCM-optimized for fast control loops and safety-critical firmware execution.
It integrates three 24-channel 12-bit ADCs, three 16-bit eMIOS timer modules (72 channels total), BCTU for cross-triggering between analog and timing peripherals, and dual LPI2C/LPSPI/FlexCAN interfaces-all with DMA support via DMAMUX.

FAQ
What is the maximum operating frequency of the S32K314NHT1MMMST?
The S32K314NHT1MMMST features a single Arm Cortex-M7 core rated for operation up to 160 MHz. This frequency is supported across the full industrial temperature range (−40 °C to +125 °C) and supply voltage range (2.97 V to 5.5 V), with integrated PLL and clock monitoring ensuring stable timing under dynamic load conditions. The S32K314NHT1MMMST achieves deterministic real-time performance using zero-wait-state TCM memory.
Does the S32K314NHT1MMMST support CAN FD?
Yes, the S32K314NHT1MMMST integrates up to six FlexCAN modules, all of which support CAN FD (Flexible Data-Rate) per ISO 11898-1:2015. Each channel operates at data rates up to 5 Mbps in FD mode and includes built-in message RAM, error counters, and loopback self-test capability. CAN FD support is enabled in hardware and requires no external transceivers beyond standard ISO 11898-2 physical layer components.
What safety certifications does the S32K314NHT1MMMST hold?
The S32K314NHT1MMMST is certified to ASIL-B per ISO 26262:2018 (up to TÜV SÜD assessment level), with integrated safety mechanisms including ECC on all memories, dual SWT timers, FCCU fault collection unit, XRDC memory protection, and CRC acceleration. It does not support ASIL-D; for that level, the S32K344NHT1MMMST variant is required. All safety documentation-including FMEDA, safety manual, and diagnostic coverage reports-is provided by NXP.
Which package options are available for the S32K314NHT1MMMST?
The S32K314NHT1MMMST is offered in MAPBGA437 (17 mm × 17 mm, 0.8 mm pitch, exposed pad), matching the pin-compatible footprint used across the S32K3xx family. Other S32K3xx variants use MAPBGA257/289, HDQFP100/172, and LQFP48 packages-but the S32K314NHT1MMMST itself is only available in MAPBGA437 per NXP's official packaging matrix and datasheet revision 14.
Does the S32K314NHT1MMMST include hardware encryption acceleration?
Yes, the S32K314NHT1MMMST includes the HSE_B (Hardware Security Engine – Basic) module, which provides dedicated AES-128/256 encryption/decryption acceleration, TRNG/PRNG, and secure key storage. It supports secure boot, firmware authentication, and OTA update signing-meeting EVITA Full security goals. RSA-4096 and ECC-521 are not implemented in HSE_B; those require HSE_F (Full) found only in S32K388/K389.
