For engineers reviewing the SPC5747CK1MMJ6R datasheet, SPC5747CK1MMJ6R pinout, SPC5747CK1MMJ6R application, or SPC5747CK1MMJ6R equivalent, this page delivers verified technical context, package mapping to 256-pin MAPBGA (MJ), validated pin functions, real-world use scenarios in vehicle networking and domain controllers, and two confirmed alternative parts with documented functional and packaging differences.

Technical Context

The SPC5747CK1MMJ6R implements a triple-core architecture with two high-performance e200Z4 CPUs supporting single-precision floating-point and VLE encoding, plus one e200Z2 CPU for deterministic low-latency tasks. All cores operate under full end-to-end ECC protection across bus transactions, covering 64-bit data and 29-bit addresses.

Its memory subsystem includes 4 MB flash (with RWW capability across 16 KB–64 KB data blocks), 512 KB SRAM distributed across three ports, and dual SMPUs (12-region each). Peripheral integration includes eight FlexCAN modules (CAN FD-capable), 18 LINFlexD channels, four DSPI, six SPI, four I²C, three SAI, ENET complex with AVB/1588 support, and dual-channel FlexRay - all accessible via multiple crossbar switches.

Key Specifications

Pinout & Package

SPC5747CK1MMJ6R is housed in a 256-pin MAPBGA (package code MJ), 15 mm × 15 mm, 0.8 mm pitch, thermally enhanced with exposed thermal pad. Pinout conforms to NXP's MPC5747G family layout per datasheet Figure 9-1 and Table 9-1.

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive microcontroller applications.

Compared with MPC5748G, SPC5747CK1MMJ6R reduces flash by 2 MB and omits USB/second Ethernet but retains identical pinout, core architecture, and safety features - making it ideal for scalable gateway designs. Against SPC5746GK1MMJ6R, it adds a second e200Z4 core and FlexRay, enabling higher-bandwidth domain consolidation without changing PCB layout.

FAQ

What is the maximum operating frequency of the SPC5747CK1MMJ6R CPU cores?

The SPC5747CK1MMJ6R integrates 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 per NXP's qualification testing and are supported by the FMPLL clock generation circuitry with 8–40 MHz external crystal input. The SPC5747CK1MMJ6R datasheet specifies these values in Section 4.2 under recommended operating conditions.

Does the SPC5747CK1MMJ6R support CAN FD communication?

Yes, the SPC5747CK1MMJ6R supports CAN FD on all eight integrated FlexCAN modules. This capability is explicitly confirmed in the MPC5748G family datasheet Table 1, which lists "8 with optional CAN FD support" for MPC5747G and MPC5748G derivatives, and is reinforced by the block diagram showing "All FlexCANs optionally support CAN FD". The SPC5747CK1MMJ6R inherits this feature as an MPC5747G variant with MJ package and 160 MHz e200Z4 cores.

What package type and pin count does the SPC5747CK1MMJ6R use?

The SPC5747CK1MMJ6R uses a 256-pin MAPBGA package (package code MJ), measuring 15 mm × 15 mm with 0.8 mm pitch and an exposed thermal pad. This matches the MPC5747G family specification in Table 1 of the datasheet and is distinct from the 176-pin LQFP-EP (KU) and 324-pin MAPBGA (MN) variants. The MJ package enables high I/O density while maintaining thermal performance for automotive under-hood environments.

How much on-chip flash and SRAM does the SPC5747CK1MMJ6R include?

The SPC5747CK1MMJ6R includes 4 MB of on-chip flash memory and 512 KB of on-chip SRAM. This is confirmed by Table 1 in the MPC5748G family datasheet, where MPC5747G is specified with "4 MB" flash and "512 KB" RAM. Flash is organized into 256 KB blocks (0x01000000–0x013FFFFF) with RWW capability across data flash regions, and SRAM is distributed across three ports with ECC protection.

Is the SPC5747CK1MMJ6R qualified for automotive functional safety standards?

Yes, the SPC5747CK1MMJ6R is designed to meet ISO 26262 ASIL-B requirements. The MPC5747G derivative shares the same safety architecture as the MPC5748G family, including end-to-end ECC, dual SMPUs, FCCU fault collection, HSMv2 security module, and diagnostic timer resources. NXP documents ASIL-B certification for the MPC5747G family in the datasheet Section 2 ("Family comparison") and associated safety manuals, confirming its suitability for automotive safety-related systems.
