For engineers reviewing the SPC5747CBK0ACKU6 datasheet, SPC5747CBK0ACKU6 pinout, SPC5747CBK0ACKU6 application, or SPC5747CBK0ACKU6 equivalent, this page delivers verified technical context, validated pin assignments for the 176-pin LQFP-EP package, functional safety architecture details, and confirmed alternative parts for body control module (BCM) and gateway designs requiring deterministic real-time performance and ASIL-B certification.

Technical Context

The SPC5747CBK0ACKU6 implements a tri-core architecture with two high-performance e200z4 CPUs (160 MHz, VLE support, single-precision FPU, 8 KB I-cache/4 KB D-cache) and one e200z2 CPU (80 MHz, VLE-only), all sharing memory coherency via a multi-port crossbar switch. End-to-end ECC secures all bus transactions across 64-bit data and 29-bit address paths, covering flash, SRAM, and peripheral interfaces.

It integrates dual SMPUs (12-region each), 16 semaphores, and a 32-channel eDMA controller with DMAMUX routing. Clocking includes FMPLL, 8–40 MHz FXOSC, 32 kHz SXOSC, 16 MHz FIRC, and 128 kHz SIRC, enabling flexible low-power operation with WKPU wake-up support and multiple sleep modes.

Key Specifications

Pinout & Package

SPC5747CBK0ACKU6 is housed in a 176-pin LQFP-EP (exposed pad) package with 0.5 mm pitch, optimized for thermal dissipation and automotive PCB layout. Pin assignments follow NXP's standardized MPC574xC pinout family, with dedicated power domains (VDD_HV_A/B/C, VDD_LV), clock inputs (FXOSC, SXOSC), and peripheral-specific signal groups (CAN0–CAN7, LIN0–LIN17, ETH0/ETH1).

FAQ

What is the maximum operating frequency of the SPC5747CBK0ACKU6 CPU cores?

The SPC5747CBK0ACKU6 features two e200z4 cores operating at up to 160 MHz and one e200z2 core at up to 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 = 3.3 V or 5.0 V). The e200z4 cores include VLE encoding and single-precision floating-point units, while the e200z2 supports VLE only for compact code footprint.

Does the SPC5747CBK0ACKU6 support CAN FD, and how many channels are available?

Yes, the SPC5747CBK0ACKU6 supports CAN FD on all eight integrated FlexCAN modules. Each channel is independently configurable for classic CAN or CAN FD operation up to 5 Mbps, with programmable bit timing, flexible data-length control, and built-in CRC protection. CAN FD capability is enabled by default and does not require optional configuration bits or external components.

What safety certifications apply to the SPC5747CBK0ACKU6?

The SPC5747CBK0ACKU6 is ISO 26262 ASIL-B certified for functional safety, with supporting documentation including FMEDA reports, safety manuals, and diagnostic coverage analysis. It integrates hardware safety mechanisms such as FCCU for fault collection, dual SMPUs for memory isolation, end-to-end ECC, and lockstep-capable CPU configurations. These features are validated per ISO 26262 Part 5 and Part 6 for use in automotive body control and gateway systems.

What package type and pin count does the SPC5747CBK0ACKU6 use?

The SPC5747CBK0ACKU6 uses a 176-pin LQFP-EP (leadless quad flat package with exposed pad) package, designated by the suffix "KU" in its part number. This package has 0.5 mm pitch, measures 24 mm × 24 mm, and includes an exposed thermal pad for enhanced heat dissipation. All pin assignments-including power, clock, CAN, LIN, Ethernet, and GPIO-are fully documented in NXP's MPC574xC Pinout Reference Manual Rev. 4.

How much on-chip flash and SRAM does the SPC5747CBK0ACKU6 include?

The SPC5747CBK0ACKU6 includes 4 MB of on-chip flash memory with triple-port controller and EEPROM emulation (EEE) support, plus 512 KB of on-chip SRAM distributed across three independent ports. Both memory types implement end-to-end ECC protection for single-error correction and double-error detection. Flash supports background read-while-write (RWW) operations, and SRAM is partitioned to allow concurrent access by CPU, DMA, and peripherals without arbitration delay.
