Product details
Overview
SPC5747GSK1MKU6 from NXP Semiconductors is a 32-bit Power Architecture® automotive microcontroller featuring dual e200z4 cores (160 MHz) and one e200z2 core (80 MHz), 4 MB on-chip flash, 512 KB SRAM with end-to-end ECC, and integrated FlexCAN, LIN, DSPI, and Ethernet interfaces. It targets vehicle gateway and body control modules requiring ASIL-B functional safety compliance and secure boot via HSMv2.
For engineers reviewing the SPC5747GSK1MKU6 datasheet, SPC5747GSK1MKU6 pinout, SPC5747GSK1MKU6 application, or SPC5747GSK1MKU6 equivalent, this page delivers verified technical context, validated pin assignments for the 176-pin LQFP-EP package, real-world automotive use cases, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The SPC5747GSK1MKU6 implements a triple-core architecture with two high-performance e200z4 CPUs supporting single-precision floating-point and VLE encoding, plus one e200z2 CPU for deterministic low-latency tasks. All cores operate under a unified memory map with SMPU-based memory protection across 16-region descriptors per unit.
Its peripheral subsystem includes eight FlexCAN modules (CAN FD-capable), 18 LINFlexD channels, four DSPI controllers, and dual 10-/12-bit ADCs synchronized via Cross Trigger Unit. Clocking relies on FMPLL with multiple oscillator inputs (FXOSC, SXOSC, FIRC, SIRC) and RTC support, while safety-critical operation is enforced by FCCU fault collection and ISO 26262 ASIL-B-certifiable features.
