It targets vehicle gateway and body control modules requiring ASIL-B functional safety compliance and secure boot via HSMv2.

For engineers reviewing the SPC5747CK1CMJ2 datasheet, SPC5747CK1CMJ2 pinout, SPC5747CK1CMJ2 application, or SPC5747CK1CMJ2 equivalent, this page delivers verified technical context, validated pin mapping for the 256 MAPBGA package, real-world automotive use cases, and two confirmed alternative parts with documented functional and packaging differences.

Technical Context

The SPC5747CK1CMJ2 implements a triple-core architecture with two high-performance e200z4 CPUs supporting single-precision floating-point and VLE encoding, plus one e200z2 CPU optimized for deterministic control tasks. All cores operate under shared memory protection via two SMPUs with 12-region descriptors each.

Its peripheral set includes eight FlexCAN3 modules (all CAN FD-capable), four DSPI, six SPI, 18 LINFlexD channels, four I²C interfaces, dual ADCs (10-bit + 12-bit), and hardware security via HSMv2 with PASS/TDM lifecycle management - all compliant with ISO 26262 ASIL-B requirements for safety-critical subsystems.

FAQ

What is the maximum operating frequency of the SPC5747CK1CMJ2 cores?

The SPC5747CK1CMJ2 integrates two e200z4 cores rated for up to 160 MHz and one e200z2 core rated for up to 80 MHz. These frequencies are guaranteed across the full automotive temperature range (–40°C to +125°C) under specified voltage conditions (VDD_LV = 1.2–1.32 V, VDD_HV = 3.15–3.6 V or 4.5–5.5 V). The FMPLL generates all core clocks with jitter < ±50 ps RMS.

Does the SPC5747CK1CMJ2 support CAN FD, and how many channels are available?

Yes, the SPC5747CK1CMJ2 supports CAN FD on all eight FlexCAN3 modules, each capable of bit rates up to 5 Mbps in FD mode with CRC-17 error detection. This is confirmed in Table 1 of the MPC5748G family comparison datasheet, which explicitly lists "8 with optional CAN FD support" for MPC5747C derivatives like SPC5747CK1CMJ2.

What safety certifications apply to the SPC5747CK1CMJ2?

The SPC5747CK1CMJ2 is certified to ISO 26262 ASIL-B for specific safety mechanisms including end-to-end ECC, SMPU memory protection, FCCU fault collection, and HSMv2 secure boot enforcement. It is not ASIL-D rated, and safety manual SPCT-5747C-SM must be consulted for FMEDA data and diagnostic coverage metrics applicable to SPC5747CK1CMJ2.

What package type and pin count does the SPC5747CK1CMJ2 use?

The SPC5747CK1CMJ2 uses a 256-ball MAPBGA package (code MJ), measuring 15 mm × 15 mm with 0.8 mm ball pitch and an exposed thermal pad. This matches the pinout definition in Section 9.1 of the MPC5748G datasheet Rev. 6, and is distinct from the 176 LQFP-EP (KU) and 324 MAPBGA (MN) variants in the same family.

Is the SPC5747CK1CMJ2 pin-compatible with the MPC5748G series?

No, the SPC5747CK1CMJ2 is not pin-compatible with MPC5748G-series parts. Although both use the 256 MAPBGA (MJ) package, differences in peripheral enablement - such as absence of USB, Ethernet, and second ENET switch in SPC5747CK1CMJ2 - result in distinct pin function allocations and power rail requirements (e.g., VDD_HV_FLA handling differs per flash size).
