Product details
Overview
SPC5748GSK1MKU6 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 processing, and secure boot.
For engineers reviewing the SPC5748GSK1MKU6 datasheet, SPC5748GSK1MKU6 pinout, SPC5748GSK1MKU6 application, or SPC5748GSK1MKU6 equivalent, this page delivers verified technical context, validated pin mapping 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 SPC5748GSK1MKU6 implements a heterogeneous multi-core architecture with two high-performance e200Z4 cores (160 MHz, VLE, single-precision FPU, 8 KB I-cache/4 KB D-cache) and one e200Z2 core (80 MHz, VLE), all sharing a triple-ported 64-bit AHB bus matrix. Memory subsystem includes 6 MB flash with three page buffers and ECC protection across all bus masters, plus 768 KB SRAM distributed across three ports with 256 KB per port.
Peripheral integration centers on automotive networking: eight FlexCAN modules (all supporting CAN FD), dual 10/100 Ethernet controllers with AVB, IEEE 1588, and L2 switching, dual-channel FlexRay 2.1, 18 LINFlexD modules, and four DSPI interfaces - all accessible via configurable I/O domains and managed by a 32-channel eDMA controller with DMAMUX routing.

Pinout & Package
SPC5748GSK1MKU6 is housed in a 176-pin LQFP-EP (exposed pad) package measuring 24 mm × 24 mm × 1.6 mm, optimized for automotive thermal and EMI requirements. Pin assignment follows NXP's standardized MPC5748G signal multiplexing scheme, with dedicated power domains (VDD_HV_A/B/C, VDD_LV), clock inputs (FXOSC/SXOSC/FIRC/SIRC), and peripheral-specific I/O banks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive gateway microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5748GSK1MJU6 | Same core configuration and peripherals, but in 256-pin MAPBGA package; higher pin count enables full peripheral concurrency (e.g., all 8 CAN FD channels + dual Ethernet + FlexRay simultaneously) | Preferred for space-constrained PCBs requiring maximum I/O density and thermal performance; not pin-compatible with SPC5748GSK1MKU6 | Select when board layout allows BGA packaging and full peripheral utilization is required; requires rework of power delivery and signal integrity design. |
| S32K344UAT0VLQY | ARM Cortex-M7-based MCU with 3 MB flash, 1.5 MB SRAM, 4× CAN FD, 1× Ethernet, no FlexRay or dual Ethernet; lacks HSMv2 but includes CSEc security engine | Better suited for cost-sensitive body control modules where FlexRay and dual Ethernet are unnecessary; lower ASIL-D capability than SPC5748GSK1MKU6's ASIL-B certified subsystems | Choose for new designs prioritizing ARM ecosystem tooling and lower BOM cost where FlexRay and dual Ethernet are excluded from requirements. |
Compared with SPC5748GSK1MKU6, MPC5748GSK1MJU6 offers identical functionality in a denser package for higher integration, while S32K344UAT0VLQY provides ARM-based scalability at the expense of FlexRay support and dual Ethernet - making SPC5748GSK1MKU6 uniquely positioned for legacy Power Architecture gateway migration and high-bandwidth automotive backbone networks.

FAQ
What is the operating temperature range for the SPC5748GSK1MKU6?
The SPC5748GSK1MKU6 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 NXP's Rev. 6 datasheet and applies to all core, memory, and peripheral functions under specified voltage conditions (VDD_HV = 3.3 V or 5 V). The SPC5748GSK1MKU6 maintains full ASIL-B compliance across this range.
Does the SPC5748GSK1MKU6 support CAN FD, and how many instances are available?
Yes, the SPC5748GSK1MKU6 supports CAN FD on all eight integrated FlexCAN modules, each configurable for Classic CAN or CAN FD operation up to 5 Mbps arbitration and 8 Mbps data phase. This capability is confirmed in the MPC5748G Family Comparison Table 1 and block diagram, and the SPC5748GSK1MKU6 implements full CAN FD protocol stack support in hardware including bit-rate switching and flexible data-length frames.
What debug interfaces does the SPC5748GSK1MKU6 provide, and are they production-ready?
The SPC5748GSK1MKU6 provides JTAG and cJTAG (IEEE 1149.7) debug interfaces compliant with IEEE-ISTO 5001-2008 Nexus Class 3+, supporting real-time trace, non-intrusive debugging, and secure access control. Both interfaces are production-enabled and fully supported by NXP's S32DS IDE and third-party tools like Lauterbach TRACE32. The SPC5748GSK1MKU6 also includes dedicated debug authentication features tied to the HSMv2 security module.
How is flash memory organized in the SPC5748GSK1MKU6, and what is its endurance?
The SPC5748GSK1MKU6 contains 6 MB of on-chip flash memory organized into 22 blocks (20 × 256 KB code blocks + 2 × 32 KB data blocks), with ECC protection applied to all reads/writes. Per NXP's datasheet Section 6.3.3, it guarantees 100,000 program/erase cycles and 20-year data retention at 125°C ambient. The SPC5748GSK1MKU6 supports Read-While-Write (RWW) on designated blocks for seamless firmware updates.
Is the SPC5748GSK1MKU6 pin-compatible with other MPC5748G variants like the MJU6 package?
No, the SPC5748GSK1MKU6 (176-pin LQFP-EP) is not pin-compatible with the MPC5748GSK1MJU6 (256-pin MAPBGA) or MNU6 (324-pin MAPBGA) variants. Pin assignments differ significantly due to package geometry and I/O bank allocation - for example, Ethernet MII signals occupy dedicated pins in the LQFP package but are multiplexed in BGA variants. Migration requires full PCB redesign; the SPC5748GSK1MKU6 pinout is fixed per NXP's datasheet Figure 9-1.
