FAQ
What is the maximum operating frequency of the S32K310NHT0MLFST?
The S32K310NHT0MLFST operates at a maximum CPU frequency of 120 MHz using its Arm Cortex-M7 core. This speed is achieved with the System PLL locked to the FXOSC or FIRC source, and is validated across the full -40 °C to 125 °C temperature range and 2.97–5.5 V supply. The S32K310NHT0MLFST does not support the 160 MHz or 240 MHz frequencies found in higher-tier S32K3xx variants like the S32K322 or S32K328.
Does the S32K310NHT0MLFST support CAN FD?
Yes, the S32K310NHT0MLFST includes three FlexCAN modules, each supporting CAN FD with data rates up to 5 Mbps. All CAN FD channels implement ISO 11898-1:2015 compliance, including bit rate switching, flexible data length (up to 64 bytes), and CRC-17/21 protection - essential for high-bandwidth body domain communication in modern vehicles.
What package options are available for the S32K310NHT0MLFST?
The S32K310NHT0MLFST is offered in HDQFP100 (100-pin thermally enhanced quad flat pack with exposed pad) and MAPBGA257 (257-ball microarray plastic ball grid array) packages. Both are RoHS-compliant, automotive-qualified, and support reflow soldering per J-STD-020. Pin assignments differ between packages and are fully documented in the S32K3xx Hardware Design Guide.
Is the S32K310NHT0MLFST certified for functional safety standards?
Yes, the S32K310NHT0MLFST is ISO 26262 ASIL-B compliant. Certification covers hardware metrics (SPFM, LFM, PMHF), safety mechanisms (ECC on all memories, dual SWT, CRC, centralized error collection), and diagnostic software libraries provided in the S32K3 SDK. It does not carry ASIL-D certification, which applies only to lockstep-core variants like the S32K341.
What debug interface does the S32K310NHT0MLFST support?
The S32K310NHT0MLFST supports Serial Wire Debug (SWD) via dedicated SWD_CLK and SWD_IO pins, compatible with ARM CoreSight debug infrastructure. It includes full SWD functionality - halt/resume, register access, memory read/write, flash programming, and trace via SWO - and is supported by NXP S32DS, SEGGER J-Link, and PE Micro debug tools.
