Overview
S32K338GHT1MPCST from NXP Semiconductors is an ASIL-B certified, three-core Arm® Cortex-M7 automotive microcontroller operating up to 240 MHz, featuring 8 MB ECC-protected program flash, 1152 KB SRAM with 384 KB TCM, and integrated QuadSPI supporting up to 2 Gbps (8-bit data width) for external memory expansion. It delivers real-time deterministic control in body electronics, gateway, and domain controller applications requiring high I/O count, CAN FD networking, and Ethernet AVB/TSN.
For engineers reviewing the S32K338GHT1MPCST datasheet, S32K338GHT1MPCST pinout, S32K338GHT1MPCST application, or S32K338GHT1MPCST equivalent, key selection criteria include triple-core lockstep-capable architecture, 3× 12-bit ADCs (24-channel each), 8× FlexCAN modules with full CAN FD support, 1 Gbps Ethernet interface, and hardware security engine (HSE_B) with AES acceleration - all validated for automotive operation from −40 °C to 125 °C.
Technical Context
The S32K338GHT1MPCST implements three independent Arm Cortex-M7 cores at 240 MHz, each with FPU, DSP, and separate I/D cache, coordinated via a 64-bit crossbar fabric and shared memory subsystem. Its safety architecture includes centralized error detection (FCCU), memory ECC on all SRAM/flash, CRC modules, and dual PLLs for clock redundancy.
It integrates a comprehensive mixed-signal subsystem: three 24-channel 12-bit ADCs, three analog comparators with internal 8-bit DACs, BCTU for cross-triggering, and eMIOS timer modules offering 72 PWM/IC/OC channels. Communication is enabled by 8 FlexCAN (CAN FD), 16 LPUART, 6 LPSPI, 2 LPI2C, 2 SAI, and 1 Gbps Ethernet with AVB/TSN support.
