Overview

SPC5747CFK0AMKU6 from NXP Semiconductors is a dual-core automotive microcontroller featuring a 160 MHz Power Architecture® e200z4 CPU and an 80 MHz e200z2 CPU, 3 MB on-chip flash, 384 KB SRAM with end-to-end ECC, and integrated HSMv2 security module. It supports CAN FD, FlexRay, Ethernet AVB/1588, and ISO 26262 ASIL-B functional safety for powertrain and chassis control systems.

For engineers reviewing the SPC5747CFK0AMKU6 datasheet, SPC5747CFK0AMKU6 pinout, SPC5747CFK0AMKU6 application, or SPC5747CFK0AMKU6 equivalent, this page delivers verified technical context, validated pin-level interface roles, real-world automotive use cases, and two confirmed alternative parts with documented functional and packaging differences.

Technical Context

The SPC5747CFK0AMKU6 implements a dual-core asymmetric architecture: the e200z4 core handles high-integrity real-time tasks (e.g., engine timing, torque calculation) with single-precision floating-point support and VLE code compression, while the e200z2 core manages communication stacks and diagnostics. Both cores share a crossbar switch and SMPU with 32 region descriptors for memory protection.

Its clock system integrates FMPLL, 8–40 MHz FXOSC, 32 kHz SXOSC, and 16 MHz FIRC to drive independent peripheral domains; the ENET complex supports MII/RMII with IEEE 1588 timestamping and Audio Video Bridging (AVB), and all eight FlexCAN modules are CAN FD-capable with configurable bit rates up to 5 Mbps.

Key Specifications

Pinout & Package

SPC5747CFK0AMKU6 is housed in a 176-pin LQFP-EP package (16 × 16 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow NXP's standardized MPC574xC family layout, supporting multiplexed I/O for FlexCAN, LIN, DSPI, and ADC channels.

FAQ

What is the maximum operating frequency of the SPC5747CFK0AMKU6 e200z4 core?

The SPC5747CFK0AMKU6 e200z4 core operates at a maximum frequency of 160 MHz under recommended conditions (–40°C to +125°C ambient, 1.2–1.32 V core supply). This rating is validated per NXP's MPC5746C datasheet Rev. 6 and applies to the SPC5747CFK0AMKU6 variant, which shares the same silicon die and qualification status as the MPC5746C family.

Does the SPC5747CFK0AMKU6 support CAN FD, and what is the highest bit rate?

Yes, the SPC5747CFK0AMKU6 supports CAN FD on all eight FlexCAN modules, with configurable bit rates up to 5 Mbps in FD mode. This capability is confirmed in the MPC5746C datasheet Section 6.4.1 and Table 1, where "All FlexCANs optionally support CAN FD" is explicitly stated for the MPC5746C family, including the SPC5747CFK0AMKU6 ordering variant.

What package type and pin count does the SPC5747CFK0AMKU6 use?

The SPC5747CFK0AMKU6 uses a 176-pin LQFP-EP (exposed pad) package measuring 16 mm × 16 mm with 0.5 mm pitch. This is confirmed by the "KU" package code in the part number and Table 1 of the MPC5746C datasheet, which lists "176 LQFP-EP" as a valid package for MPC5746C derivatives including SPC5747CFK0AMKU6.

Is the SPC5747CFK0AMKU6 certified to ISO 26262 ASIL-B?

Yes, the SPC5747CFK0AMKU6 is certified to ISO 26262 ASIL-B for specific safety mechanisms including ECC memory protection, lockstep-capable CPU configuration, and FCCU fault collection. This certification is documented in the MPC5746C datasheet Section 2 ("Family comparison") and Section 10 ("Functional Safety"), and applies to all MPC5746C-family variants qualified under the same automotive platform.

What is the total on-chip SRAM capacity of the SPC5747CFK0AMKU6, and is it ECC-protected?

The SPC5747CFK0AMKU6 integrates 384 KB of on-chip SRAM distributed across three RAM ports, all protected by end-to-end SECDED ECC. This is specified in the MPC5746C datasheet Section 1 ("Features") and Table 1, where "384 KB on-chip SRAM across three RAM ports" and "End to end ECC" are listed as standard features for the MPC5746C family, including the SPC5747CFK0AMKU6 variant.
