Product details
Overview
S32K322EHT0MPBIR from NXP Semiconductors is a dual-core Arm® Cortex-M7 automotive MCU rated ASIL B, operating at up to 160 MHz, with 2 MB ECC-protected program flash, 256 KB ECC SRAM (including 192 KB TCM), and integrated QuadSPI interface supporting up to 480 Mbps. It targets body control modules and gateway ECUs in harsh automotive environments.
For engineers reviewing the S32K322EHT0MPBIR datasheet, S32K322EHT0MPBIR pinout, S32K322EHT0MPBIR application, or S32K322EHT0MPBIR equivalent, key selection criteria include dual-core real-time determinism, CAN FD support across four FlexCAN modules, Ethernet AVB/TSN capability, and hardware security engine (HSE-B) for AES acceleration - all validated for -40 °C to 125 °C operation.
Technical Context
The S32K322EHT0MPBIR implements two independent Arm Cortex-M7 cores, each with FPU, DSP, I/D-cache, and zero-wait TCM RAM, enabling parallel real-time task partitioning. Its cross-trigger architecture tightly couples eMIOS timers, ADCs, and BCTU for deterministic sensor-to-actuator latency.
Power management uses a simplified RUN/STANDBY model with peripheral-specific clock gating; safety is enforced via ECC on all memories, CRC modules, dual SWT timers, and XRDC-based memory access protection. The HSE-B provides AES acceleration but excludes RSA/ECC crypto per device variant documentation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K342EHT0MPBIR | ASIL D lockstep dual-core variant with identical package and peripheral set; adds redundant core checking and enhanced safety mechanisms | Required for steering angle sensor or brake-by-wire sub-systems demanding higher fault coverage | Select when ISO 26262 ASIL D decomposition applies; requires additional safety software certification effort |
| S32K312EHT0MPBIR | ASIL B single-core variant with same 2 MB flash and 256 KB SRAM but reduced peripheral count (no Ethernet, only 3× FlexCAN) | Suitable for cost-optimized body nodes where Ethernet or multi-domain routing is unnecessary | Choose for non-gateway BCMs with lower I/O density and no time-sensitive network bridging needs |
Compared with S32K322EHT0MPBIR, the S32K342EHT0MPBIR adds lockstep safety enforcement at the cost of ~15% higher power and stricter toolchain qualification, while the S32K312EHT0MPBIR reduces system complexity and BOM cost by removing Ethernet and one FlexCAN channel - making it optimal for isolated body nodes.

FAQ
What is the maximum operating frequency of the S32K322EHT0MPBIR?
The S32K322EHT0MPBIR features two independent Arm Cortex-M7 cores, each capable of running at up to 160 MHz. 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, with performance sustained via integrated I/D caches and zero-wait TCM RAM. The S32K322EHT0MPBIR does not support higher frequencies like the 240 MHz variants found in the S32K328 or S32K338 families.
Does the S32K322EHT0MPBIR support CAN FD, and how many channels are available?
Yes, the S32K322EHT0MPBIR integrates four FlexCAN modules, each fully supporting CAN FD (Flexible Data-Rate) per ISO 11898-1:2015, including bit rates up to 5 Mbps and payload lengths up to 64 bytes. These channels operate independently and can be configured for different baud rates and message filters, enabling concurrent communication with powertrain, chassis, and body networks without software arbitration overhead.
What package type and pin count does the S32K322EHT0MPBIR use?
The S32K322EHT0MPBIR is packaged in a MAPBGA437 (17 mm × 17 mm, 0.8 mm pitch) with an exposed thermal pad. This 437-ball grid array supports high I/O density required for automotive domain controllers, including dedicated pins for Ethernet RMII, multiple CAN transceivers, QuadSPI, and 320 GPIOs - with 60 pins supporting wakeup capability and 32 supporting configurable interrupts.
Is the S32K322EHT0MPBIR qualified for automotive safety standards?
Yes, the S32K322EHT0MPBIR is certified ASIL B compliant per ISO 26262:2018. Its safety features include ECC on all on-chip memories (flash, SRAM, TCM), dual independent software watchdog timers (SWT), centralized error detection (FCCU), memory protection unit (MPU), and XRDC-based access control. It does not include ASIL D-level lockstep or redundant core checking, which are present in the S32K342EHT0MPBIR variant.
Does the S32K322EHT0MPBIR include hardware security acceleration?
Yes, the S32K322EHT0MPBIR integrates the HSE-B (Hardware Security Engine – Basic) module, which provides hardware-accelerated AES encryption/decryption (128/192/256-bit keys). It does not support RSA or ECC acceleration - those capabilities are reserved for higher-tier variants like S32K388/S32K389. The HSE-B firmware is field-upgradable and includes side-channel attack protections aligned with EVITA Full requirements.
