FAQ

What is the maximum operating frequency of the S32K310NHT0VLFST?

The S32K310NHT0VLFST operates at up to 120 MHz using its Arm Cortex-M7 core. This frequency is achieved with the System PLL (SPLL) locked to the Fast External Oscillator (FXOSC) or Fast Internal RC oscillator (FIRC). The device maintains full functionality across its entire -40 °C to 125 °C temperature range at this speed, with no derating required. All timing-critical peripherals - including eMIOS timers and ADC sampling - are synchronized to this core clock domain in the S32K310NHT0VLFST.

Does the S32K310NHT0VLFST support CAN FD?

Yes, the S32K310NHT0VLFST supports CAN FD on all three integrated FlexCAN modules. Each channel supports data bit rates up to 5 Mbps and payloads up to 64 bytes, enabling high-throughput communication for modern vehicle networks. CAN FD frame handling is implemented in hardware with dedicated message buffers and acceptance filtering, reducing CPU load during bus arbitration. This capability is confirmed in the S32K3xx Data Sheet Rev. 14 for the S32K310NHT0VLFST variant.

What package options are available for the S32K310NHT0VLFST?

The S32K310NHT0VLFST is offered in multiple packages: LQFP48, HDQFP100, MAPBGA257, and MAPBGA289. The "NHT0" suffix in the part number specifically denotes the MAPBGA257 package with 0.8 mm ball pitch and exposed thermal pad. This package supports high-density automotive PCB layouts while providing adequate thermal dissipation for continuous operation at 120 MHz. Pin-compatible migration to other S32K3xx devices is supported within the same package variant.

Is the S32K310NHT0VLFST qualified for automotive safety standards?

Yes, the S32K310NHT0VLFST is ISO 26262 ASIL-B compliant. It integrates functional safety mechanisms including dual Software Watchdog Timers (SWT), Error-Correcting Code (ECC) on all memories, centralized error collection via FCCU, and hardware-assisted self-tests. These features are validated per ISO 26262 Part 5 requirements and documented in the S32K3xx Functional Safety Manual. The S32K310NHT0VLFST does not support ASIL-D; that level requires lockstep cores found only in S32K34x variants.

Does the S32K310NHT0VLFST include hardware cryptographic acceleration?

Yes, the S32K310NHT0VLFST includes the Hardware Security Engine (HSE-B), which accelerates AES-128/256 encryption/decryption and SHA-256 hashing. It supports secure boot authentication, encrypted firmware updates, and key provisioning with tamper-resistant key storage. HSE-B firmware is field-upgradable and meets EVITA Full security goals. This feature is present across the entire S32K3xx family, including the S32K310NHT0VLFST, and is distinct from the optional HSE-A used in higher-tier variants.
