For engineers reviewing the SPC5748GK1MKU6 datasheet, SPC5748GK1MKU6 pinout, SPC5748GK1MKU6 application, or SPC5748GK1MKU6 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 SPC5748GK1MKU6 implements a heterogeneous multi-core architecture: two high-performance e200Z4 CPUs execute at up to 160 MHz with single-precision floating-point units and VLE instruction encoding, while the auxiliary e200Z2 core runs at 80 MHz for dedicated real-time control tasks. All cores share end-to-end ECC protection across bus transactions, covering 64-bit data and 29-bit addresses.
Its peripheral subsystem includes dual Ethernet controllers (one with integrated L2 switch), eight FlexCAN FD interfaces, four DSPIs, six SPIs, 18 LINFlexD modules, three SAI audio interfaces, and dual ADCs (10-bit and 12-bit) synchronized via Cross Trigger Unit - all coordinated through a multi-port crossbar switch enabling concurrent access to flash, RAM, and peripherals by multiple bus masters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5746GK1MKU6 | Same package (176 LQFP-EP), but 3 MB flash, 512 KB SRAM, no second Ethernet or FlexRay; lacks HSMv2 and only 4 FlexCAN FD channels | Suitable for cost-sensitive body control modules where dual Ethernet and full gateway bandwidth are unnecessary | Select when gateway functionality is limited to CAN/LIN bridging without Ethernet backbone or advanced security needs. |
| SPC58NG84C3MKU6 | ARM Cortex-R52 dual-core (300 MHz), 8 MB flash, 2 MB SRAM, same 176 LQFP-EP package; supports ASIL-D, includes PCIe and more CAN FD channels | Targets next-gen zonal controllers requiring higher compute throughput, PCIe connectivity to AI accelerators, and ASIL-D compliance | Choose for future-proofed designs needing ARM ecosystem compatibility, higher performance, and extended safety certification beyond ASIL-B. |
Compared with MPC5746GK1MKU6, SPC5748GK1MKU6 adds 3 MB flash, 256 KB SRAM, dual Ethernet with AVB, and HSMv2 - making it essential for full-featured gateways. Versus SPC58NG84C3MKU6, it offers Power Architecture continuity and lower entry cost but trades ARM scalability and ASIL-D readiness.

FAQ
What is the maximum operating frequency of each CPU core in the SPC5748GK1MKU6?
The SPC5748GK1MKU6 integrates two e200Z4 cores rated at 160 MHz and one e200Z2 core rated at 80 MHz. These frequencies are guaranteed across the full automotive temperature range (-40°C to +125°C ambient) under specified supply conditions (VDD_LV = 1.2–1.32 V, VDD_HV = 3.3 V or 5 V). The e200Z4 cores support dual-issue execution and single-precision floating-point operations, while the e200Z2 provides deterministic real-time control.
Does the SPC5748GK1MKU6 support CAN FD, and how many interfaces are available?
Yes, the SPC5748GK1MKU6 supports CAN FD on all eight FlexCAN 3.0 modules. Each interface operates at bit rates up to 5 Mbps in FD mode and is fully compatible with ISO 11898-1:2015. The controller handles FD frame formatting, bit rate switching, and payload length extension in hardware - eliminating software overhead for high-bandwidth diagnostic and control messaging in modern vehicle networks.
What package type and pin count does the SPC5748GK1MKU6 use?
The SPC5748GK1MKU6 uses a 176-pin Low-Profile Quad Flat Package with Exposed Pad (LQFP-EP), identified by the "KU" package code in its orderable part number. This package supports thermal dissipation requirements for automotive under-hood applications and is pin-compatible with other MPC5748G variants in the same KU footprint, including MPC5747GK1MKU6 and MPC5746GK1MKU6.
How is functional safety implemented in the SPC5748GK1MKU6?
The SPC5748GK1MKU6 achieves ISO 26262 ASIL-B compliance through hardware-enforced safety mechanisms: dual System Memory Protection Units (SMPUs) with 16-region granularity, Fault Collection and Control Unit (FCCU) for error detection and reporting, end-to-end ECC on all memory and bus transactions, and lockstep-capable debug interfaces. These features are validated per ISO 26262 Part 5 and documented in NXP's safety manual for the MPC5748G family.
What is the role of the Hardware Security Module (HSMv2) in the SPC5748GK1MKU6?
The HSMv2 in the SPC5748GK1MKU6 is a dedicated, isolated security co-processor that performs cryptographic operations (AES-128/256, SHA-256, RSA-2048), manages secure key storage, enforces secure boot verification, and supports device lifecycle management via Password and Device Security (PASS/TDM) features. It operates independently of the main CPU cores to prevent side-channel attacks and ensure confidentiality of sensitive keys and firmware images.
