Overview
SPC5747CFK0ACKU6 from NXP Semiconductors is an automotive-qualified Power Architecture® 32-bit microcontroller featuring dual e200z4 cores (160 MHz) and one e200z2 core (80 MHz), 4 MB on-chip flash, 512 KB SRAM with end-to-end ECC, and integrated FlexCAN3 with FD support. It targets body control modules requiring ASIL-B functional safety compliance, real-time deterministic execution, and multi-protocol connectivity in 176-pin LQFP-EP packaging.
For engineers reviewing the SPC5747CFK0ACKU6 datasheet, SPC5747CFK0ACKU6 pinout, SPC5747CFK0ACKU6 application, or SPC5747CFK0ACKU6 equivalent, this device delivers verified dual-core deterministic control, hardware security module (HSMv2)-enabled secure boot, and production-ready CAN FD/Ethernet/LIN interface integration for automotive ECU designs.
Technical Context
The SPC5747CFK0ACKU6 implements a triple-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) sharing memory via a multi-port crossbar switch. All bus masters generate SECDED codes for 64-bit data + 29-bit address transactions across flash, SRAM, and peripherals.
It integrates dual SMPUs (12-region each), 16 semaphores, 32-channel eDMA, Boot Assist Flash (BAF), and peripheral clusters including 48+32-channel ADCs (10-/12-bit), 18 LINFlexD modules, eight FlexCAN3 controllers (CAN FD-capable), four DSPI, six SPI, four I²C, three SAI, dual Ethernet (MII/RMII + AVB/1588), uSDHC, and FlexRay 2.1 - all operating under ISO 26262 ASIL-B certified safety mechanisms.

Pinout & Package
SPC5747CFK0ACKU6 uses a 176-pin LQFP-EP package with exposed thermal pad. Pin functions are defined per multiplexed signal groups (e.g., SIUL0, SIUL1, eMIOS, DSPI, FlexCAN, LINFlexD, ADC, USB, Ethernet) and include dedicated power/ground, clock, reset, debug (JTAG/cJTAG/Nexus), and safety monitoring pins (WKPU, CMU, FCCU).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_HV_A / VDD_HV_B / VDD_HV_C | High-voltage I/O supply rails | Independent 3.3 V or 5 V supplies for I/O banks; enable mixed-voltage interfacing with legacy automotive sensors and actuators. |
| VDD_LV | Core logic supply | 1.2–1.32 V regulated supply for e200z4/z2 cores; requires external decoupling per FPREG stability specs. |

FAQ
What is the maximum operating frequency of each CPU core in the SPC5747CFK0ACKU6?
The SPC5747CFK0ACKU6 features two e200z4 cores operating at up to 160 MHz and one e200z2 core running at up to 80 MHz. These frequencies are validated across the full automotive temperature range (–40°C to +125°C) and supported by the FMPLL clock generation system with frequency modulation capability. The SPC5747CFK0ACKU6 datasheet specifies these values under recommended operating conditions with proper voltage regulation and thermal management.
Does the SPC5747CFK0ACKU6 support CAN FD, and how many channels are available?
Yes, the SPC5747CFK0ACKU6 supports CAN FD on all eight FlexCAN3 modules, each capable of data rates up to 5 Mbps in FD mode. This is confirmed in the MPC5748G family comparison table and block diagram, where "All FlexCANs optionally support CAN FD" applies to the SPC5747C variant. The SPC5747CFK0ACKU6 implements the full FlexCAN3 peripheral set with FD frame handling, bit rate switching, and CRC enhancements.
What safety certifications apply to the SPC5747CFK0ACKU6?
The SPC5747CFK0ACKU6 is ISO 26262 ASIL-B certified for specific safety-related functions, including memory ECC, SMPU-based memory protection, FCCU fault reporting, and HSMv2 cryptographic operations. Certification documentation covers hardware elements and safety mechanisms - not full-system compliance. The SPC5747CFK0ACKU6 datasheet and NXP's functional safety manual provide detailed FMEDA results and diagnostic coverage metrics for each safety feature.
What package type and pin count does the SPC5747CFK0ACKU6 use?
The SPC5747CFK0ACKU6 uses a 176-pin LQFP-EP (lead-free, exposed pad) package measuring 24 mm × 24 mm with 0.5 mm pitch. This package is explicitly listed in Table 1 of the MPC5748G family comparison document and confirmed in the ordering information section, where "KU" denotes the 176 LQFP-EP option. The exposed pad enhances thermal dissipation for sustained operation in automotive under-hood environments.
Is the SPC5747CFK0ACKU6 pin-compatible with other members of the MPC5748G family?
No, the SPC5747CFK0ACKU6 is not pin-compatible with higher-pin-count variants like the 256- or 324-ball BGA packages (e.g., MPC5748G). However, it shares identical pinout and signal mapping with other 176-pin LQFP-EP variants in the family (e.g., SPC5746C, SPC5748G in KU package), enabling PCB reuse across derivatives with different flash/SRAM configurations or peripheral enablement. Pin compatibility is limited to the same package code (KU) and validated in NXP's package migration guides.
