FAQ

What is the maximum operating frequency of the S32K322NHT0MPAST?

The S32K322NHT0MPAST features two independent Arm Cortex-M7 cores, each capable of operating at up to 160 MHz. This frequency is supported across the full industrial temperature range (-40 °C to 125 °C) and voltage range (2.97 V to 5.5 V), enabling high-throughput real-time processing for automotive control applications. The S32K322NHT0MPAST achieves this performance with zero-wait-state TCM RAM and dual I/D caches to minimize memory latency impact.

Does the S32K322NHT0MPAST support CAN FD?

Yes, the S32K322NHT0MPAST supports CAN FD on all four integrated FlexCAN modules. Each channel operates at up to 5 Mbps in the data phase while maintaining backward compatibility with classical CAN 2.0B at 1 Mbps arbitration rate. This capability is confirmed in the S32K3xx Data Sheet Rev. 14 and applies directly to the S32K322NHT0MPAST variant, enabling high-bandwidth communication for ADAS and powertrain domains.

What package type is used for the S32K322NHT0MPAST?

The S32K322NHT0MPAST uses the MAPBGA437 package: a 17 mm × 17 mm ball grid array with 437 I/O balls, 0.8 mm pitch, and an exposed thermal pad. This package is explicitly listed in the S32K3xx Data Sheet for the S32K322 family and supports automotive thermal dissipation requirements and high-pin-count peripheral routing for complex ECU designs.

Is the S32K322NHT0MPAST qualified for automotive safety standards?

Yes, the S32K322NHT0MPAST is certified to ASIL-B per ISO 26262, with hardware-level safety features including ECC on all memories, dual software watchdog timers (SWT), centralized error detection, and XRDC-based memory access control. These mechanisms are documented in the S32K3xx Data Sheet Rev. 14 and apply specifically to the S32K322NHT0MPAST, enabling its use in body control, chassis, and gateway applications requiring functional safety compliance.

Does the S32K322NHT0MPAST include hardware security acceleration?

Yes, the S32K322NHT0MPAST integrates the HSE_B hardware security engine, which provides dedicated acceleration for AES-256 encryption/decryption, SHA-256 hashing, and ECDSA signature verification. This engine is present in all S32K322 variants per the S32K3xx Data Sheet Rev. 14 and enables secure boot, firmware authentication, and runtime cryptographic operations without CPU overhead - a confirmed feature of the S32K322NHT0MPAST.
