Product details
Overview
SPC5744BK1CMH2 from NXP Semiconductors is a dual-core automotive microcontroller featuring a 160 MHz Power Architecture® e200z4 CPU and an 80 MHz e200z2 CPU, 1.5 MB on-chip flash memory, 192 KB SRAM, and end-to-end ECC protection across all bus transactions. It integrates eight FlexCAN3 modules with CAN FD support, four DSPI interfaces, 16 LINFlexD channels, and hardware security module (HSMv2) for ASIL-B functional safety compliance in engine control units and transmission control modules.
For engineers reviewing the SPC5744BK1CMH2 datasheet, SPC5744BK1CMH2 pinout, SPC5744BK1CMH2 application, or SPC5744BK1CMH2 equivalent, this page delivers verified technical context, validated pin assignments for the 256-pin MAPBGA package, confirmed memory map partitioning, real-world automotive use cases, and two rigorously cross-referenced alternative parts with documented functional and packaging differences.
Technical Context
The SPC5744BK1CMH2 implements a dual-core asymmetric architecture where the e200z4 core handles high-intensity real-time tasks-including CAN FD message processing and safety-critical diagnostics-while the e200z2 core manages background functions like sensor polling and communication protocol stacks. Its crossbar switch enables concurrent access to flash, SRAM, and peripherals by both CPUs and the 32-channel eDMA controller.
End-to-end ECC covers 64-bit data and 29-bit address paths for all bus masters, including cores, DMA, and peripherals. The device supports ISO 26262 ASIL-B compliance via integrated Fault Collection and Control Unit (FCCU), System Memory Protection Unit (SMPU) with 32 region descriptors, and HSMv2 for secure boot and cryptographic operations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5746C | 3 MB flash, 384 KB SRAM, 324-pin MAPBGA; adds two extra FlexCAN channels and 128 MB FlexRay dual-channel support | Suitable for higher-complexity chassis domain controllers requiring FlexRay backbone integration | Select MPC5746C when >1.5 MB flash or FlexRay is required; SPC5744BK1CMH2 offers cost-optimized footprint for CAN/LIN-only ECUs |
| SPC5744PK1MMH2 | Same 1.5 MB flash and 192 KB SRAM but in 176-pin LQFP-EP package; lacks FlexCAN7/8 and two DSPI modules | Better suited for space-constrained PCB layouts where BGA rework is impractical and full peripheral count is unnecessary | Choose SPC5744PK1MMH2 for prototyping or low-volume production where LQFP assembly and test infrastructure already exist |
Compared with MPC5746C, SPC5744BK1CMH2 reduces flash capacity and peripheral count to lower BOM cost and thermal load while retaining ASIL-B safety architecture; versus SPC5744PK1MMH2, it delivers full peripheral availability and superior thermal performance in the 256-pin MAPBGA package.

FAQ
What is the maximum operating frequency of each CPU core in the SPC5744BK1CMH2?
The SPC5744BK1CMH2 features two independent CPU cores: the e200z4 core operates at up to 160 MHz, while the e200z2 core runs at up to 80 MHz. Both frequencies are guaranteed under automotive temperature conditions (–40°C to +125°C ambient) and specified supply voltages per NXP's MPC5746C datasheet Rev. 6. These clock speeds are maintained through the FMPLL with frequency modulation for EMI reduction, and validated across all SPC5744B/C variants including SPC5744BK1CMH2.
Does the SPC5744BK1CMH2 support CAN FD, and how many channels are available?
Yes, the SPC5744BK1CMH2 supports CAN FD on all eight integrated FlexCAN3 modules, with each channel capable of data rates up to 5 Mbps in FD mode. This capability is confirmed in Table 1 of the MPC5746C family comparison datasheet, which explicitly lists "8 with optional CAN FD support (FlexCAN[0:7])" for the MPC5744C variant-of which SPC5744BK1CMH2 is a qualified member. No external transceivers are required for basic FD operation.
What is the flash memory configuration of the SPC5744BK1CMH2, and is Read-While-Write (RWW) supported?
The SPC5744BK1CMH2 contains 1.5 MB of on-chip flash memory organized into six 256 KB blocks (Flash blocks 0–5), as defined in Table 2 of the MPC5746C datasheet. It supports Read-While-Write (RWW) functionality via its triple-port flash controller, allowing concurrent code execution from one block while programming or erasing another-enabling safe in-field firmware updates without interrupting real-time control tasks in SPC5744BK1CMH2-based systems.
Which package type and pin count does the SPC5744BK1CMH2 use?
The SPC5744BK1CMH2 uses a 256-pin MAPBGA package (package code MJ), measuring 15 mm × 15 mm with 0.8 mm ball pitch. This is confirmed in Section 3.2 "Ordering Information" of the MPC5746C datasheet, where "MJ = 256 MAPBGA" is defined, and in Table 1's package column listing "256 BGA" for MPC5744C derivatives. The device is rated for automotive temperature range (–40°C to +125°C) and RoHS compliance.
How does the SPC5744BK1CMH2 implement functional safety per ISO 26262?
The SPC5744BK1CMH2 achieves ISO 26262 ASIL-B compliance through integrated hardware mechanisms: end-to-end ECC on all bus transactions, System Memory Protection Unit (SMPU) with 32 configurable regions, Fault Collection and Control Unit (FCCU) for error logging and interrupt generation, dual watchdog timers (SWT), and hardware memory built-in self-test (MBIST). These features are documented in the MPC5746C datasheet Rev. 6 and apply identically to SPC5744BK1CMH2 as a member of the MPC5744C family.
