FAQ

What is the maximum operating frequency of the S32K376NHT1MJBST?

The S32K376NHT1MJBST operates at a maximum core frequency of 320 MHz using its dual Arm Cortex-M7 cores in lockstep mode. This frequency is achieved via the PLLDIG module driven by the FXOSC crystal oscillator or FIRC internal RC source, with clock monitoring enforced by CMU_FC to ensure timing integrity under ASIL-D requirements. The S32K376NHT1MJBST maintains this frequency across its full −40°C to +125°C operating range with appropriate voltage regulation.

Does the S32K376NHT1MJBST support CAN FD?

Yes, the S32K376NHT1MJBST integrates up to four FlexCAN FD controllers compliant with ISO 11898-1:2015, supporting data rates up to 5 Mbps in FD mode and classic CAN up to 1 Mbps. Each controller includes message RAM with configurable ID filters, loopback testing, and error counters - all accessible via the AIPS_Lite bridge with safety monitoring through FCCU and ERM. This capability is confirmed in Chapter 76 of the S32K396RM reference manual.

What safety certifications does the S32K376NHT1MJBST hold?

The S32K376NHT1MJBST is AEC-Q100 Grade 1 qualified and fully compliant with ISO 26262 up to ASIL-D for both hardware and software development processes. Its safety architecture includes lockstep CPU execution, FCCU fault collection, CMU_FC/CMU_FM clock monitoring, REG_PROT register protection, and STCU2 self-test - all documented in Chapters 44–49 and 51–52 of the S32K396RM. NXP provides certified safety manuals and FMEDA reports for S32K376NHT1MJBST.

How much embedded flash memory does the S32K376NHT1MJBST include?

The S32K376NHT1MJBST includes 8 MB of embedded flash memory with built-in ECC (Error Correction Code) for single-bit correction and double-bit detection. This flash is partitioned into multiple blocks with independent erase/write control and supports secure boot via HSE_B-verified DCF records. Flash endurance is rated at 100,000 write/erase cycles, and retention exceeds 20 years at 125°C - specifications confirmed in Chapter 20 of the S32K396RM reference manual.

Is the S32K376NHT1MJBST pin-compatible with other S32K3 series MCUs?

The S32K376NHT1MJBST uses a 208-pin LQFP package identical to the S32K396NHT1MJBST, enabling mechanical and footprint compatibility. However, not all signals are functionally mapped identically - for example, eTPU and COOLFLUX DSP signals present on S32K396 are NC on S32K376. Pin compatibility is limited to shared peripherals (FlexCAN, LPUART, eFlexPWM, ADC); full drop-in replacement requires validation of signal routing and software configuration against the S32K376NHT1MJBST-specific signal multiplexing table.
