Overview
S32K348GHT1MJBST from NXP Semiconductors is an ASIL-D-certified, lockstep dual-core Arm Cortex-M7 automotive microcontroller operating up to 240 MHz, featuring 8 MB ECC-protected program flash, 1152 KB SRAM with 192 KB TCM, and integrated Ethernet (1 Gbps AVB/TSN), eight FlexCAN modules with CAN FD support, and triple 12-bit ADCs for body control and powertrain applications.
For engineers reviewing the S32K348GHT1MJBST datasheet, S32K348GHT1MJBST pinout, S32K348GHT1MJBST application, or S32K348GHT1MJBST equivalent, this page delivers verified core frequency, memory configuration, safety certification level, interface count, and package mapping - all confirmed for the exact S32K348GHT1MJBST variant per NXP S32K3xx Rev. 14 datasheet.
Technical Context
The S32K348GHT1MJBST implements two Arm Cortex-M7 cores in lockstep configuration with hardware redundancy, dedicated error detection circuitry (FCCU, CMU), and centralized fault management (EIM/ERM) to meet ISO 26262 ASIL-D requirements. It integrates a 64-bit crossbar fabric, dual PLLs, and 2×24-channel eMIOS timers for deterministic real-time control.
Its memory subsystem includes RWW (Read-While-Write) capability for OTA updates via A/B swap, ECC on all memories, and instruction/data caches with zero-wait TCM to minimize latency in safety-critical control loops. The HSE-B security engine supports AES-256, RSA-4096, and ECC-521 with firmware-upgradable cryptographic services.
