Product details
Overview
SPC5748GSK0AMKU6 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 with ECC, 768 KB SRAM, and integrated HSMv2 security module. It supports ASIL-B functional safety compliance and delivers deterministic real-time control for vehicle gateway applications requiring CAN FD, FlexRay, Ethernet AVB, and LIN.
For engineers reviewing the SPC5748GSK0AMKU6 datasheet, SPC5748GSK0AMKU6 pinout, SPC5748GSK0AMKU6 application, or SPC5748GSK0AMKU6 equivalent, this part enables high-integrity communication routing, secure boot, and mixed-signal processing in automotive domain controllers where clock accuracy, memory integrity, and peripheral concurrency are critical selection criteria.
Technical Context
The SPC5748GSK0AMKU6 implements a triple-core heterogeneous architecture: two e200Z4 CPUs (160 MHz, single-precision FPU, VLE support) handle high-throughput tasks like protocol stack offload and packet switching, while the e200Z2 core (80 MHz, VLE-optimized) manages low-latency I/O and safety monitoring. All cores share end-to-end ECC protection across 64-bit data and 29-bit address paths.
Its peripheral subsystem includes eight FlexCAN3 modules with CAN FD support, dual-channel FlexRay 2.1, 10/100 Ethernet with IEEE 1588 and AVB, and three SAI interfaces with fractional clock dividers - all accessible via concurrent crossbar switches and managed by a 32-channel eDMA controller with DMAMUX routing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5748GSK0AMJU6 | Same core, memory, and peripheral set but in 256-pin MAPBGA package; higher pin count enables full FlexRay + dual Ethernet + USB routing | Better suited for space-constrained PCB layouts requiring maximum peripheral concurrency and thermal dissipation | Select when board layout demands finer pitch, improved thermal performance, or additional GPIOs beyond 129 available in LQFP |
| SPC574SCK0MLU6 | Single e200Z4 core (160 MHz), 4 MB flash, no FlexRay, reduced CAN FD count (4 channels), no Ethernet or USB | Targeted at cost-sensitive body electronics with lower bandwidth and safety requirements (ASIL-A only) | Choose for non-gateway applications where gateway-level throughput, security, and protocol diversity are unnecessary |
Compared with MPC5748GSK0AMJU6, the SPC5748GSK0AMKU6 offers identical functionality in a more manufacturable LQFP package but trades off some routing flexibility and thermal headroom. Against SPC574SCK0MLU6, it provides full gateway-class capability-including dual FlexRay, 8 CAN FD channels, and Ethernet-with ASIL-B certification and HSMv2 security.

FAQ
What is the operating temperature range for the SPC5748GSK0AMKU6?
The SPC5748GSK0AMKU6 is qualified for automotive operation from –40°C to +125°C ambient temperature (TA), with junction temperature (TJ) rated up to +150°C. This rating is validated per AEC-Q100 Grade 1 and supports deployment in engine bay, transmission, and under-hood gateway locations where thermal stress is significant. The device includes on-die thermal monitoring and automatic throttling to maintain reliability within these limits.
Does the SPC5748GSK0AMKU6 support CAN FD, and what is its maximum data rate?
Yes, the SPC5748GSK0AMKU6 integrates eight FlexCAN3 modules, each supporting CAN FD with programmable bit timing and data rates up to 5 Mbit/s in FD mode. All CAN FD channels implement ISO 11898-1 compliant transceiver interfaces and support automatic protocol switching between classical CAN and CAN FD frames. The SPC5748GSK0AMKU6 also includes dedicated message RAM and interrupt prioritization for deterministic handling of high-priority FD traffic.
How does the SPC5748GSK0AMKU6 implement functional safety per ISO 26262?
The SPC5748GSK0AMKU6 achieves ISO 26262 ASIL-B compliance through hardware features including end-to-end ECC on all memory and buses, dual SMPUs with 16-region granularity, FCCU fault collection unit, lockstep-capable watchdog timers (SWT), and built-in self-test (MBIST/LBIST). Its safety manual documents diagnostic coverage metrics, failure modes, and safe states-enabling integration into ASIL-B systems without requiring external safety monitors for core memory and bus integrity.
What debug interfaces does the SPC5748GSK0AMKU6 support, and are they production-enabled?
The SPC5748GSK0AMKU6 supports IEEE-ISTO 5001-2008 Nexus Class 3+ debug interfaces on both e200Z4 and e200Z2 cores, plus JTAG and cJTAG (IEEE 1149.7) boundary scan. These interfaces remain fully functional in production devices and support real-time trace, memory access, and breakpoint debugging without disabling safety mechanisms. Debug authentication is enforced via HSMv2, preventing unauthorized access to secure memory regions during development or field service.
Can the SPC5748GSK0AMKU6 execute secure boot from internal flash, and how is it configured?
Yes, the SPC5748GSK0AMKU6 supports secure boot via Boot Assist Flash (BAF) using HSMv2-managed cryptographic verification. During reset, the BAF loader validates the signature of the first flash sector using ECDSA-256 against keys stored in HSMv2's secure key store. Configuration is controlled by BOOT_CFG pins and secured boot policy registers; once enabled, unsigned firmware images are rejected and the device enters safe mode. This process is immutable and tamper-resistant per Common Criteria EAL5+ requirements.
