Product details
Overview
SPC5747GK1CKU6 from NXP Semiconductors is an automotive-qualified Power Architecture® microcontroller featuring dual 160 MHz e200z4 cores and one 80 MHz e200z2 core, 4 MB on-chip flash, 512 KB SRAM with end-to-end ECC, and integrated FlexCAN3 with FD support. It targets vehicle gateway and body control modules requiring ASIL-B functional safety compliance, real-time deterministic execution, and multi-protocol communication in engine control units and domain controllers.
For engineers reviewing the SPC5747GK1CKU6 datasheet, SPC5747GK1CKU6 pinout, SPC5747GK1CKU6 application, or SPC5747GK1CKU6 equivalent, this part delivers verified CAN FD, Ethernet (RMII/MII), LINFlexD, DSPI, and USB OTG/SPH interfaces - all validated for automotive powertrain and chassis systems operating at –40°C to +125°C ambient temperature.
Technical Context
The SPC5747GK1CKU6 implements a triple-core heterogeneous architecture: two high-performance e200z4 cores (160 MHz) with single-precision floating-point units and VLE instruction encoding, plus one e200z2 core (80 MHz) optimized for low-latency background tasks. All cores share a unified memory map backed by ECC-protected 64-bit AHB interconnect and three SMPUs with 12-region descriptors each.
Its peripheral subsystem integrates eight FlexCAN3 modules (all supporting CAN FD), four DSPI controllers, six SPI ports, 18 LINFlexD channels, three SAI audio interfaces, and dual ENET complexes with IEEE 1588 timestamping and AVB support - all accessible via a multi-port crossbar switch enabling concurrent bus master access without arbitration stalls.

FAQ
What is the maximum operating frequency of the SPC5747GK1CKU6 CPU cores?
The SPC5747GK1CKU6 features two e200z4 cores rated at 160 MHz and one e200z2 core rated at 80 MHz. These frequencies are guaranteed across the full –40°C to +125°C ambient temperature range under specified voltage conditions (VDD_LV = 1.2–1.32 V, VDD_HV = 3.15–3.6 V or 4.5–5.5 V). The cores operate independently with shared memory resources managed by the AHB crossbar.
Does the SPC5747GK1CKU6 support CAN FD, and how many interfaces are available?
Yes, the SPC5747GK1CKU6 supports CAN FD on all eight FlexCAN3 modules. Each interface operates at up to 5 Mbps data phase and maintains full ISO 11898-1 compliance. The device implements CAN FD with flexible data-length support (up to 64 bytes), CRC-17 error detection, and bit-rate switching - validated in NXP's MPC5748G reference design and automotive qualification reports.
What safety certifications apply to the SPC5747GK1CKU6?
The SPC5747GK1CKU6 is ISO 26262 ASIL-B certified for specific functions including CPU lockstep monitoring, ECC memory protection, SMPU-based memory isolation, and FCCU fault reporting. Certification documentation covers hardware architectural metrics (SPFM, LFM) and tool qualification reports. It does not achieve ASIL-D out-of-box but supports ASIL-D decomposition when combined with external monitors.
What package type and pin count does the SPC5747GK1CKU6 use?
The SPC5747GK1CKU6 uses a 176-pin LQFP-EP (leadless quad flat package with exposed thermal pad) with 0.5 mm pitch and 24 mm × 24 mm body size. This package exposes 129 general-purpose I/Os, 17 dedicated GPIs, and full JTAG/cJTAG/Nexus debug signals - matching the pinout defined in NXP document MPC5748G Rev. 6, Section 9.1.
Is the SPC5747GK1CKU6 pin-compatible with other members of the MPC5748G family?
No, the SPC5747GK1CKU6 is not pin-compatible with MPC5748G or MPC5746G variants. While all share the KU (176 LQFP-EP) package option, differences in peripheral multiplexing, power domain assignments, and signal routing - particularly for ENET, USB, and FlexRay - result in distinct pin functions. Board-level compatibility requires verification against NXP's MPC5748G Family Comparison Table and package-specific signal descriptions.
