Product details
Overview
SPC5747CK1VKU6 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 hardware security module (HSMv2). It supports ISO 26262 ASIL-B–certifiable functions in vehicle gateway and body control applications.
For engineers reviewing the SPC5747CK1VKU6 datasheet, SPC5747CK1VKU6 pinout, SPC5747CK1VKU6 application, or SPC5747CK1VKU6 equivalent, this page delivers verified technical context, validated pin assignments for the 176-pin LQFP-EP package, confirmed functional safety architecture, and real-world substitution guidance aligned with NXP's official family documentation.
Technical Context
The SPC5747CK1VKU6 implements a triple-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 deterministic real-time task partitioning. All cores operate under full end-to-end ECC protection across buses, flash, and SRAM.
It integrates dual System Memory Protection Units (SMPU_0/SMPU_1, each with 12 region descriptors), 96-channel eMIOS timer subsystem, 18 LINFlexD modules, eight FlexCAN3 controllers (CAN FD-capable), and a 3-port Ethernet switch supporting AVB, IEEE 1588, and multi-queue operation - all mapped to dedicated AHB crossbar resources without arbitration contention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Configuration | 2× e200Z4 @ 160 MHz + 1× e200Z2 @ 80 MHz; enables parallel safety-critical and non-safety tasks with independent cache and ECC domains. |
| Flash Memory | 4 MB on-chip flash with triple-port controller and EEE emulation; supports RWW (Read-While-Write) for seamless firmware updates. |
| SRAM | 512 KB on-chip SRAM across three ports, fully protected by SECDED ECC; eliminates external RAM dependency in ASIL-B designs. |
| Functional Safety | ISO 26262 ASIL-B certified per core and peripheral cluster; includes FCCU fault collection, HSMv2 security engine, and dual SMPUs. |
| Communication Interfaces | 8× FlexCAN3 (CAN FD), 18× LINFlexD, 4× DSPI, 6× SPI, 4× I²C, 3× SAI, ENET + L2 switch; meets full vehicle network gateway requirements. |
| Package & Pin Count | 176-pin LQFP-EP (KU package); provides 129 GPIOs with configurable I/O domains for CAN, LIN, Ethernet, USB, and general-purpose use. |
| Operating Temperature | –40 °C to +125 °C ambient (Grade M); qualified for under-hood and powertrain-adjacent deployment. |
Pinout & Package
SPC5747CK1VKU6 is housed in a 176-pin LQFP-EP (exposed pad) package with 0.5 mm pitch, 24 × 24 mm body size, and thermal pad optimized for automotive PCB thermal management. Pin assignments follow NXP's official MPC5747G pinout documentation (Rev. 6, Section 9.1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_HV_A / VDD_HV_B / VDD_HV_C | High-voltage I/O supply inputs | Independent 3.3 V or 5 V supplies for I/O banks; enable mixed-voltage domain interfacing (e.g., 5 V LIN transceivers + 3.3 V CAN PHYs). |
| VDD_LV | Core logic supply input | 1.2–1.32 V regulated supply for e200Z4/Z2 cores; requires external decoupling per Table 8 (Clp/ulp_reg = 0.8–1.4 µF). |
| FXOSC_IN / FXOSC_OUT | Main crystal oscillator interface | 8–40 MHz external crystal connection; feeds FMPLL for system clock generation and jitter-sensitive peripherals (e.g., Ethernet, USB). |
| SXOSC_IN / SXOSC_OUT | 32 kHz real-time clock crystal | Enables RTC/API operation during low-power modes; supports wake-up via WKPU without main oscillator activation. |
| BOOT_CFG[2:0] | Boot mode configuration pins | Determines boot source (internal flash, SCI, LIN, or BAF); latched at reset and must be externally pulled to defined states. |
| ESR0 / ESR1 | External watchdog reset outputs | Fail-safe reset signals driven by SWT modules; used to reset external safety monitors or power management ICs. |
Key Features
| Feature | Design Value |
|---|---|
| Triple-core heterogeneous execution | Enables ASIL-B software partitioning: e200Z4 cores handle safety-critical CAN/FlexRay/Ethernet stacks while e200Z2 manages LIN diagnostics and low-latency I/O. |
| End-to-end ECC memory protection | Covers all bus masters, flash array, SRAM blocks, and cache lines - detects and corrects single-bit errors, detects double-bit errors in real time. |
| HSMv2 hardware security module | Provides AES-128/256, SHA-256, RSA-2048 acceleration, secure key storage, and life-cycle management for OTA firmware signing and secure boot. |
| Configurable I/O domains | Allows voltage-level isolation between CAN FD (5 V tolerant), LIN (12 V tolerant), Ethernet (3.3 V), and general-purpose GPIOs on shared pinmux. |
| Multi-queue Ethernet switching | Supports AVB traffic shaping, IEEE 1588 timestamping, and hardware-accelerated VLAN filtering - critical for time-sensitive automotive networking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5748GK1VKU6 | 6 MB flash, 768 KB SRAM, dual SMPU with 16 regions each, HSMv2 optional (not standard), adds second Ethernet port and FlexRay support. | Targeted at higher-tier gateways requiring dual Ethernet AVB domains and FlexRay backbone integration. | Select when >4 MB flash, >512 KB SRAM, or FlexRay 2.1 compliance is required; otherwise SPC5747CK1VKU6 offers optimal cost/performance for mid-tier gateways. |
| SPC5746CK1VKU6 | 3 MB flash, 512 KB SRAM, no HSMv2, SMPU_0 only (12 regions), limited FlexCAN count (6 vs 8), no Ethernet switch. | Suitable for entry-level BCMs or junction boxes where CAN/LIN connectivity suffices without Ethernet or advanced security. | Choose for cost-sensitive body electronics where cryptographic acceleration, ASIL-B certification, or multi-gigabit networking are unnecessary. |
Compared with MPC5748GK1VKU6, SPC5747CK1VKU6 trades FlexRay and dual Ethernet for lower cost and identical safety certification; versus SPC5746CK1VKU6, it adds HSMv2, two extra FlexCANs, and full Ethernet switching - making it the minimal viable part for ASIL-B gateway designs requiring CAN FD and OTA security.
