Product details
Overview
SPC5747GK1CKU2 from NXP Semiconductors is an automotive-qualified Power Architecture® 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 vehicle gateway and body control modules requiring ASIL-B functional safety compliance, real-time deterministic execution, and multi-protocol communication.
For engineers reviewing the SPC5747GK1CKU2 datasheet, SPC5747GK1CKU2 pinout, SPC5747GK1CKU2 application, or SPC5747GK1CKU2 equivalent, this page delivers verified technical context, validated pin mapping for the 176 LQFP-EP package, confirmed memory architecture, functional safety implementation details, and two rigorously cross-referenced alternative parts for gateway-class automotive MCU selection.
Technical Context
The SPC5747GK1CKU2 implements a tri-core heterogeneous architecture: two high-performance e200z4 CPUs (160 MHz, VLE-enabled, single-precision FPU, 8 KB I-cache/4 KB D-cache) plus one e200z2 CPU (80 MHz, VLE-only) for dedicated safety monitor or low-latency tasks. All cores operate with full end-to-end ECC across buses, flash, and RAM - covering 64-bit data and 29-bit addresses with SECDED protection.
Its peripheral subsystem includes eight FlexCAN3 modules (all supporting CAN FD), four DSPI, six SPI, 18 LINFlexD channels, four I²C, three SAI, dual Ethernet (MII/RMII + IEEE 1588 AVB), and dual-channel FlexRay 2.1 - all routed via multiple crossbar switches to enable concurrent access without arbitration bottlenecks. Clocking is managed by FMPLL, FXOSC (8–40 MHz), SXOSC (32 kHz), FIRC (16 MHz), and SIRC (128 kHz).

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive gateway microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5748GK1MJU2 | 6 MB flash, 768 KB SRAM, 324 MAPBGA package, adds third Ethernet port and second FlexRay channel. | Targeted at high-end gateways requiring >6 MB OTA image storage and dual FlexRay backbone connectivity. | Select when needing larger code space, higher I/O count (246 GPIO), or additional Ethernet/FlexRay bandwidth beyond SPC5747GK1CKU2 capability. |
| SPC5746GK1CKU2 | 3 MB flash, 512 KB SRAM, no HSMv2, no FlexRay, reduced CAN count (6 vs 8), same 176 LQFP-EP package. | Suitable for cost-sensitive body controllers where security and FlexRay are not required. | Select for non-security-critical BCM designs where flash footprint <3 MB and CAN FD count ≤6 suffices; lower BOM cost than SPC5747GK1CKU2. |
Compared with MPC5748GK1MJU2, SPC5747GK1CKU2 trades flash capacity and FlexRay for LQFP manufacturability and lower thermal envelope; versus SPC5746GK1CKU2, it adds HSMv2, two extra FlexCAN3 channels, and ASIL-B certification - making it the minimal viable part for certified gateway deployments.
