FAQ

What is the maximum operating frequency of the S32K358GHT1MJBSR?

The S32K358GHT1MJBSR features an Arm Cortex-M7 core rated for up to 240 MHz operation. This frequency is achievable across the full −40 °C to +125 °C ambient temperature range and 2.97 V to 5.5 V supply voltage, as verified in the official NXP S32K3xx Data Sheet Rev. 14. The S32K358GHT1MJBSR uses dual PLLs and optimized clock gating to sustain this performance while maintaining ASIL-D compliance.

Does the S32K358GHT1MJBSR support CAN FD?

Yes, the S32K358GHT1MJBSR integrates eight FlexCAN modules, and all channels support CAN FD (Controller Area Network with Flexible Data-Rate) per ISO 11898-1:2015. Each module supports bit rates up to 5 Mbps, payload lengths up to 64 bytes, and CRC-17 error detection - confirmed in the S32K3xx Data Sheet section "Communications Interfaces". The S32K358GHT1MJBSR does not require external transceivers for CAN FD physical layer compliance.

Is the S32K358GHT1MJBSR qualified for automotive use?

Yes, the S32K358GHT1MJBSR is AEC-Q100 Grade 1 qualified (−40 °C to +125 °C) and ISO 26262 ASIL-D certified. It includes hardware safety mechanisms such as lockstep-ready CPU architecture, FCCU fault collection, dual SWT watchdogs, and ECC on all memories - all documented in the S32K3xx Functional Safety Manual. These qualifications make the S32K358GHT1MJBSR suitable for production automotive ECUs without derating.

What package type does the S32K358GHT1MJBSR use?

The S32K358GHT1MJBSR is offered exclusively in the MAPBGA437 package: 17 mm × 17 mm body, 0.8 mm ball pitch, with exposed thermal pad. This package is pin-compatible with other high-end S32K3xx variants including S32K344, S32K348, and S32K388 - enabling hardware reuse across safety and performance tiers. The S32K358GHT1MJBSR's pinout is defined in the S32K3xx Data Sheet Appendix A.

Does the S32K358GHT1MJBSR include hardware security features?

Yes, the S32K358GHT1MJBSR integrates the HSE-B (Hardware Security Engine – Basic) subsystem, which provides AES-256, RSA-4096, ECC-521 acceleration, TRNG, and side-channel attack resistance - meeting EVITA Full security goals. It supports secure boot, key injection, and runtime attestation. The S32K358GHT1MJBSR's HSE-B is functionally identical to that in S32K348GHT1MJBSR and S32K388GHT1MJBSR, as specified in the S32K3xx Security Reference Manual.
