Product details
Overview
SPC5748GBK0AVKU6 from NXP Semiconductors is an automotive-qualified Power Architecture® microcontroller featuring dual 160 MHz e200z4 cores and one 80 MHz e200z2 core, 6 MB on-chip flash, 768 KB SRAM with end-to-end ECC, and integrated HSMv2 security module. It supports ASIL-B functional safety compliance and targets vehicle gateway and domain controller applications requiring high-integrity communication, real-time control, and secure boot.
For engineers reviewing the SPC5748GBK0AVKU6 datasheet, SPC5748GBK0AVKU6 pinout, SPC5748GBK0AVKU6 application, or SPC5748GBK0AVKU6 equivalent, this page delivers verified technical context, validated pin-level design meaning, confirmed automotive-grade operating parameters (–40°C to +125°C), and two rigorously cross-checked alternative parts for gateway-class MCU selection.
Technical Context
The SPC5748GBK0AVKU6 implements a triple-core heterogeneous architecture: two high-performance e200z4 CPUs (160 MHz, single-precision FPU, VLE support) handle time-critical gateway routing and protocol translation, while the e200z2 core (80 MHz, VLE-optimized) manages background diagnostics and low-power monitoring. All cores share memory via a multi-port crossbar switch and are protected by dual SMPUs with 16-region granularity.
Its communication subsystem includes eight FlexCAN3 modules with CAN FD support, four DSPI, six SPI, 18 LINFlexD channels, four I²C interfaces, dual Ethernet controllers (10/100 with AVB, IEEE 1588, MII/RMII), and a dual-channel FlexRay 2.1 controller - all coordinated through a 32-channel eDMA with DMAMUX routing and synchronized by a Cross Trigger Unit for ADC-timer event alignment.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive gateway microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5746G | 4 MB flash, 512 KB SRAM, no HSMv2, 6× FlexCAN (no CAN FD), single Ethernet | Lacks CAN FD and dual Ethernet; insufficient for high-bandwidth gateway architectures requiring AVB or time-sensitive networking | Select when cost-sensitive body control applications require ASIL-B but not CAN FD or Ethernet switching |
| S32K344 | Arm Cortex-M7 @ 320 MHz, 4 MB flash, 1.5 MB SRAM, HSE security engine, 4× CAN FD, single Ethernet | Different ISA and toolchain; lacks FlexRay and MLB support; higher core performance but no native Power Architecture ecosystem compatibility | Choose for new Arm-based designs prioritizing compute density and AUTOSAR Adaptive support over legacy Power Architecture integration |
