Product details
Overview
S32K322EHT0MPBIT from NXP Semiconductors is an ASIL-B dual-core Arm® Cortex-M7 automotive microcontroller operating up to 160 MHz, featuring 2 MB program flash with ECC, 256 KB SRAM (including 192 KB TCM), and dual FlexCAN modules with CAN FD support - deployed in body control modules requiring real-time deterministic response under harsh environmental conditions.
For engineers reviewing the S32K322EHT0MPBIT datasheet, S32K322EHT0MPBIT pinout, S32K322EHT0MPBIT application, or S32K322EHT0MPBIT equivalent, key selection criteria include dual-core lockstep readiness, QuadSPI interface for external memory expansion, Ethernet AVB/TSN capability, and functional safety compliance for automotive ECU designs.
Technical Context
The S32K322EHT0MPBIT implements two independent Arm Cortex-M7 cores running at up to 160 MHz each, with separate I/D caches and dedicated TCM RAM to minimize latency in motor control and real-time safety-critical loops. It integrates a 64-bit crossbar switch fabric enabling concurrent high-bandwidth access to flash, SRAM, and peripherals.
Its safety architecture includes hardware error detection on all memories (ECC), centralized fault collection (FCCU), dual SWT timers, and XRDC-based memory protection - all aligned to ISO 26262 ASIL-B requirements without requiring lockstep configuration. The device supports RWW (Read-While-Write) flash for seamless OTA updates via A/B swap.
