Product details
Overview
SPC5748GK0AVKU6 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, body control, and domain controller applications requiring high-integrity communication and real-time processing.
For engineers reviewing the SPC5748GK0AVKU6 datasheet, SPC5748GK0AVKU6 pinout, SPC5748GK0AVKU6 application, or SPC5748GK0AVKU6 equivalent, this page delivers verified technical context, validated pin assignments for the 176-pin LQFP-EP package, confirmed CAN FD/Ethernet/USB/FlexRay peripheral support, and two rigorously cross-checked alternative parts for gateway-class automotive MCU selection.
Technical Context
The SPC5748GK0AVKU6 implements a heterogeneous multi-core architecture with two high-performance e200Z4 CPUs (160 MHz, VLE, single-precision FPU, 8 KB I-cache/4 KB D-cache) and one e200Z2 CPU (80 MHz, VLE), all sharing a triple-ported 64-bit AHB bus with SMPU-based memory protection. Its clock system integrates FMPLL, 8–40 MHz FXOSC, 32 kHz SXOSC, and 16 MHz FIRC to drive multiple synchronous domains.
Peripheral subsystems include eight FlexCAN3 modules with CAN FD support, dual 10/100 Ethernet controllers with AVB/IEEE 1588, two USB controllers (OTG + SPH), uSDHC, dual-channel FlexRay 2.1, and three SAI audio interfaces - all accessible via concurrent crossbar switching and managed by a 32-channel eDMA with DMAMUX routing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive gateway microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5748GK0AVMJ6 | Same core, memory, and peripheral set but in 256-pin MAPBGA package; higher pin count enables more Ethernet PHY traces and additional CAN/LIN channels | Better suited for space-constrained PCB layouts requiring dense routing of multiple high-speed interfaces | Select when board layout demands finer-pitch routing, thermal performance beyond LQFP limits, or need for >176 I/O signals |
| SPC574SADK0MLU6 | Single e200Z4 core @ 160 MHz, 4 MB flash, 512 KB SRAM, no FlexRay or second Ethernet; HSMv2 retained | Targeted at cost-sensitive body control modules where full gateway feature set is unnecessary | Choose for non-gateway applications needing ASIL-B compliance and HSMv2 but lower peripheral count and reduced BOM cost |
Compared with SPC5748GK0AVKU6, MPC5748GK0AVMJ6 offers identical functionality in a smaller footprint with superior thermal performance, while SPC574SADK0MLU6 reduces complexity and cost for non-gateway roles - both require revalidation of pin mapping and layout but share toolchain and safety certification assets.
