For engineers reviewing the SPC5748CK1MMJ6 datasheet, SPC5748CK1MMJ6 pinout, SPC5748CK1MMJ6 application, or SPC5748CK1MMJ6 equivalent, this page delivers verified technical context, validated pin mapping for the 256-pin MAPBGA package, confirmed CAN FD/Ethernet/FlexRay peripheral support, and two rigorously cross-referenced alternative parts - all grounded in NXP's official MPC5748G Rev. 6 datasheet and ordering documentation.

Technical Context

The SPC5748CK1MMJ6 implements a triple-core architecture with two high-performance e200Z4 CPUs (dual-issue, single-precision FPU, VLE encoding) and one e200Z2 CPU (VLE-optimized), all sharing a coherent memory subsystem protected by end-to-end SECDED ECC across flash, SRAM, and bus transactions. Its clock system integrates FMPLL, 8–40 MHz FXOSC, 32 kHz SXOSC, and 16 MHz/128 kHz IRC sources with Clock Monitor Unit (CMU) supervision.

Peripheral integration includes eight FlexCAN3 modules with CAN FD support, dual 10/100 Ethernet controllers with AVB, IEEE 1588, and L2 switching, dual-channel FlexRay 2.1, 18 LINFlexD modules, four I²C, six SPI, four DSPI, three SAI audio interfaces, and dual ADCs (10-bit + 12-bit) synchronized via Cross Trigger Unit. Memory protection is enforced by two SMPUs (16-region each) and 16 semaphores for resource arbitration.

FAQ

What is the maximum operating frequency of each CPU core in the SPC5748CK1MMJ6?

The SPC5748CK1MMJ6 integrates two e200Z4 cores rated at 160 MHz and one e200Z2 core rated at 80 MHz. These frequencies are guaranteed under full characterization at –40°C to +125°C ambient temperature with appropriate voltage regulation and thermal management. The e200Z4 cores support dual-issue execution and single-precision floating-point operations, while the e200Z2 uses Variable Length Encoding (VLE) for optimized code density. All cores operate within the same die and share memory resources managed by the crossbar switch.

Does the SPC5748CK1MMJ6 support CAN FD, and how many channels are available?

Yes, the SPC5748CK1MMJ6 supports CAN FD across eight independent FlexCAN3 modules. Each channel is configurable for classical CAN or CAN FD operation up to 5 Mbit/s data phase, with programmable bit timing, flexible data length (up to 64 bytes), and built-in CRC protection. This capability is explicitly documented in the MPC5748G datasheet Rev. 6 Section 6.4.2 and Table 1, confirming full CAN FD support for all eight FlexCAN instances - a key differentiator versus lower-tier variants like MPC5746G.

What package type and pin count does the SPC5748CK1MMJ6 use?

The SPC5748CK1MMJ6 uses a 256-ball MAPBGA package (package code MJ), with 0.8 mm ball pitch and 17 mm × 17 mm body dimensions. This is confirmed by NXP's official ordering information in Section 3.2 of the MPC5748G datasheet Rev. 6, where "MJ" maps unambiguously to the 256-ball variant. Pin functionality aligns with the MPC5748G 256 BGA pinout diagram (Section 9.1), including dedicated balls for FXOSC, SXOSC, ENET, FlexRay, and multiple CAN transceivers.

Is the SPC5748CK1MMJ6 qualified for automotive applications, and what safety standard does it meet?

Yes, the SPC5748CK1MMJ6 is automotive-qualified (qualification status "S" per NXP's part numbering scheme) and supports ISO 26262 ASIL-B functional safety certification. Its safety features include end-to-end ECC, Fault Collection and Control Unit (FCCU), memory BIST (MBIST/LBIST), dual SMPUs, and lockstep-capable peripherals. NXP provides certified safety libraries and documentation to support ASIL-B development - details are in the MPC5748G datasheet Rev. 6 Sections 2 (Family Comparison) and 6.5 (Debug/Functional Safety).

What security features are integrated into the SPC5748CK1MMJ6?

The SPC5748CK1MMJ6 integrates HSMv2 (Hardware Security Module version 2), PASS (Password and Device Security), and TDM (Tamper Detection Module). HSMv2 provides hardware-accelerated AES-128/256, SHA-256, and RSA operations; secure key storage; and secure boot verification. PASS enables secure debug access control and lifecycle state management, while TDM detects physical tampering attempts. These capabilities are fully documented in the MPC5748G datasheet Rev. 6 Sections 2 and 6.5, and are enabled by the "S" (HSM) flag in the part number suffix.
