Product details
Overview
S32K328NHT1VPCSR from NXP Semiconductors is an ASIL-B 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 QuadSPI supporting up to 2 Gbps at 8-bit width. It delivers real-time control for body electronics, gateway modules, and domain controllers in harsh automotive environments.
For engineers reviewing the S32K328NHT1VPCSR datasheet, S32K328NHT1VPCSR pinout, S32K328NHT1VPCSR application, or S32K328NHT1VPCSR equivalent, key selection criteria include dual-core deterministic timing, CAN FD support across eight FlexCAN modules, Ethernet AVB/TSN (1 Gbps), and hardware safety features including ECC on all memories and centralized error detection per ISO 26262.
Technical Context
The S32K328NHT1VPCSR implements two independent Arm Cortex-M7 cores running at up to 240 MHz each, with separate I/D caches, FPU, DSP extensions, and zero-wait-state TCM RAM. Its memory subsystem includes 8 MB on-chip flash with read-while-write (RWW) and A/B swap for OTA updates.
Timing and communication are tightly integrated: three eMIOS modules provide 72 timer channels, BCTU enables cross-triggering between ADCs and timers, and the fabric supports concurrent high-bandwidth access via 64-bit Xbar-critical for simultaneous CAN FD, Ethernet, and FlexIO operation in automotive gateways.
