Overview
SPC5748GSK1MKU6R 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 is designed for vehicle gateway and domain controller applications requiring high-integrity communication, real-time processing, and secure boot.
For engineers reviewing the SPC5748GSK1MKU6R datasheet, SPC5748GSK1MKU6R pinout, SPC5748GSK1MKU6R application, or SPC5748GSK1MKU6R equivalent, this part delivers deterministic multi-core execution, CAN FD (8 channels), FlexRay, Ethernet AVB/1588, and hardware-accelerated cryptography - critical for automotive network gateways, body control modules, and ADAS domain controllers where timing predictability, memory integrity, and secure firmware updates are mandatory.
Technical Context
The SPC5748GSK1MKU6R implements a heterogeneous multi-core architecture with two high-performance e200Z4 CPUs (160 MHz, VLE + single-precision FPU) and one e200Z2 CPU (80 MHz, VLE-only), all sharing coherent memory via triple-ported 64-bit AHB crossbar. End-to-end ECC secures all bus transactions across flash, SRAM, and peripherals using SECDED over 64-bit data + 29-bit address paths.
Its peripheral set includes eight FlexCAN3 modules with CAN FD support, dual 10/100 Ethernet controllers with AVB, multi-queue, and IEEE 1588 timestamping, a dual-channel FlexRay 2.1 controller, and three Synchronous Audio Interfaces (SAI) with fractional clock dividers - enabling time-synchronized audio routing and deterministic network bridging in automotive infotainment and central gateway systems.

The SPC5748GSK1MKU6R is qualified for automotive Grade 1 operation, supporting ambient temperatures from –40 °C to +125 °C. Its junction temperature rating extends to +150 °C, enabling reliable deployment in under-hood environments such as engine compartments and battery management units where thermal stress is significant. This specification is validated per AEC-Q100 Rev G.
Does the SPC5748GSK1MKU6R support CAN FD, and how many channels are available?
Yes, the SPC5748GSK1MKU6R supports CAN FD across all eight FlexCAN3 modules, each capable of data rates up to 5 Mbps in FD mode. These channels are fully configurable for classic CAN or CAN FD operation, with hardware message filtering, RAM-based mailboxes, and time-triggered communication support - essential for high-bandwidth vehicle networking in modern gateways.
How does the Boot Assist Flash (BAF) function work on the SPC5748GSK1MKU6R?
The Boot Assist Flash (BAF) on the SPC5748GSK1MKU6R enables in-field firmware updates via LIN or SCI serial interfaces without requiring JTAG access. During reset, BAF executes from ROM and allows reprogramming of internal flash through a defined command protocol - supporting secure, authenticated OTA updates and field recovery for safety-critical automotive ECUs.
What security features are implemented in the SPC5748GSK1MKU6R's Hardware Security Module (HSMv2)?
The SPC5748GSK1MKU6R integrates HSMv2 with dedicated cryptographic accelerators for AES-128/256, SHA-256, RSA-2048, and ECC; a True Random Number Generator (TRNG); secure key storage; and secure boot verification. It complies with EVITA Medium and supports UNECE R155/R156 cybersecurity management system (CSMS) requirements for automotive software updates.
Is the SPC5748GSK1MKU6R pin-compatible with other members of the MPC5748G family?
No - the SPC5748GSK1MKU6R uses the 176-pin LQFP-EP (KU) package, while other MPC5748G variants use 256 or 324 MAPBGA packages (MJ/MN). Pinouts differ significantly across packages due to I/O count, power pin distribution, and peripheral mapping. Migration requires PCB redesign; however, software compatibility is maintained across the MPC5748G family via consistent register maps and SDK support.
