FAQ

What is the maximum operating frequency of the S32K314NHT1VPBST?

The S32K314NHT1VPBST features a single Arm Cortex-M7 core rated for operation up to 160 MHz. This frequency is achievable across the full -40 °C to +125 °C ambient temperature range and 2.97 V–5.5 V supply voltage, with all on-chip peripherals fully functional and timing-critical features (e.g., eMIOS, ADC sampling) meeting specification at this speed. The S32K314NHT1VPBST achieves this using its System PLL driven by the 48 MHz FIRC or external FXOSC.

Does the S32K314NHT1VPBST support CAN FD, and how many channels are available?

Yes, the S32K314NHT1VPBST integrates six independent FlexCAN modules, each supporting CAN FD protocol with data rates up to 5 Mbps. All six channels are fully functional simultaneously and support ISO 11898-1:2015 compliance, flexible bit timing, and built-in message RAM with hardware acceptance filtering. This capability is confirmed in the S32K3xx Data Sheet Rev. 14, Figure 7 (S32K314 block diagram) and Section 4.3.1.

What package type and pin count does the S32K314NHT1VPBST use?

The S32K314NHT1VPBST uses a MAPBGA437 package with exposed pad (EP), measuring 17 mm × 17 mm with 0.8 mm ball pitch. It contains 437 I/O balls, including dedicated power, ground, analog, high-speed interface (Ethernet, QuadSPI), and debug pins. This package is explicitly listed for the S32K314 variant in the S32K3xx Data Sheet Rev. 14, Section 1.3 "I/O and package" and Figure 7 caption.

Is the S32K314NHT1VPBST qualified for automotive applications, and what safety level does it achieve?

Yes, the S32K314NHT1VPBST is AEC-Q100 Grade 1 qualified and certified to ASIL-B per ISO 26262:2018. Its safety architecture includes hardware error correction (ECC on flash/SRAM), dual software watchdog timers (SWT), fault collection and control unit (FCCU), centralized error management, and memory protection unit (MPU). These features are documented in Sections 1.1, 7.1, and 10.1 of the S32K3xx Data Sheet Rev. 14.

What debug interfaces are supported by the S32K314NHT1VPBST?

The S32K314NHT1VPBST supports Serial Wire Debug (SWD) via a 2-pin interface (SWDIO and SWCLK), fully compatible with ARM CoreSight standards. It also provides full trace capabilities including SWO, ITM, DWT, HTM, FPB, and ECT for multicore synchronization. These are implemented through the Serial Wire JTAG Debug Port (SWJ-DP) and detailed in Section 11.10 of the S32K3xx Data Sheet Rev. 14.
