Product details
Overview
SPC5744BK1CMH2R 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 with end-to-end ECC, and integrated hardware security module (HSMv2). It supports CAN FD, FlexRay, Ethernet AVB, and ISO 26262 ASIL-B functional safety for powertrain control applications.
For engineers reviewing the SPC5744BK1CMH2R datasheet, SPC5744BK1CMH2R pinout, SPC5744BK1CMH2R application, or SPC5744BK1CMH2R equivalent, this page delivers verified technical context, validated pin assignments, real-world use cases in engine management and transmission control, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The SPC5744BK1CMH2R implements a dual-core heterogeneous architecture: the high-performance e200z4 core handles real-time powertrain computation and safety-critical tasks, while the e200z2 core manages communication stacks and peripheral coordination. Both cores operate under shared memory protection via a 32-region SMPU and synchronized access through a crossbar switch.
It integrates eight FlexCAN3 modules with CAN FD support, dual-channel FlexRay 2.1, 10/100 Ethernet with IEEE 1588 and AVB, and a dedicated HSMv2 for secure boot, key management, and cryptographic acceleration - all validated for ASIL-B compliance per ISO 26262.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5746C | 3 MB flash, 384 KB SRAM, 8 FlexCAN, 324 BGA option; no HSMv2 standard - optional add-on | Higher memory capacity supports complex AUTOSAR Classic/Adaptive stacks and OTA update partitions | Select when requiring >2 MB flash or 324-pin package for expanded peripheral routing |
| SPC574SADK1AKLQ | 176-pin LQFP-EP package, 1.5 MB flash, 192 KB SRAM, same dual-core and HSMv2; lacks FlexRay and Ethernet | Targeted at cost-sensitive body control modules where CAN FD and LIN suffice | Select for space-constrained PCBs needing thermal pad but no high-speed networking interfaces |
Compared with MPC5746C and SPC574SADK1AKLQ, the SPC5744BK1CMH2R uniquely balances FlexRay/Ethernet capability with 256-pin BGA compactness and factory-integrated HSMv2 - making it optimal for mid-tier domain controllers requiring both safety and networking without full 324-pin footprint.

FAQ
What is the maximum operating temperature range for the SPC5744BK1CMH2R?
The SPC5744BK1CMH2R is rated for ambient operation from –40 °C to +125 °C, with junction temperature up to +150 °C. This specification aligns with automotive under-hood requirements and is validated per AEC-Q100 Grade 1. The device maintains full functionality and ECC integrity across this range, and thermal derating is not required below 125 °C ambient. SPC5744BK1CMH2R uses internal temperature sensing and dynamic voltage scaling to sustain timing margins at elevated temperatures.
Does the SPC5744BK1CMH2R include hardware security features out of the box?
Yes, the SPC5744BK1CMH2R integrates HSMv2 and Password and Device Security (PASS) as standard silicon features - not optional add-ons. These provide AES-128/256 encryption, SHA-256 hashing, RSA-2048 signing, secure boot verification, and lifecycle state management. SPC5744BK1CMH2R supports UNECE R155 compliance and enables secure OTA updates without external secure elements. All cryptographic operations execute within the isolated HSM boundary.
Which communication protocols does the SPC5744BK1CMH2R support natively without external transceivers?
The SPC5744BK1CMH2R includes native digital logic for CAN FD, LIN, SPI, I²C, DSPI, FlexRay, and Ethernet MAC layers - but physical layer (PHY) interfacing requires external transceivers for CAN FD, FlexRay, and Ethernet. Only LIN and I²C signals can connect directly to buses. SPC5744BK1CMH2R provides dedicated pins for ETH_MII/RMII, CAN_TX/RX, and FRAY_TxD/RxD, all electrically buffered but not PHY-integrated.
Is the SPC5744BK1CMH2R pin-compatible with other members of the SPC574x family?
No, the SPC5744BK1CMH2R is not pin-compatible with other SPC574x variants due to differing package footprints and signal allocations. While it shares the 256-pin MAPBGA (MJ) package with SPC5746C-MJ variants, pin functions differ significantly - especially for FlexRay, Ethernet, and HSM-related signals. SPC5744BK1CMH2R has unique FS0–FS2 safety configuration pins and dedicated HSM clock routing not present in non-HSM derivatives. Board redesign is required for substitution.
What debug interfaces are supported by the SPC5744BK1CMH2R?
The SPC5744BK1CMH2R supports JTAG (IEEE 1149.1) and cJTAG (IEEE 1149.7) for boundary scan and core debugging, plus Nexus Class 3+ trace for both e200z4 and e200z2 cores. Debug access is secured via PASS-controlled authentication, and trace output is configurable to exclude sensitive memory regions. SPC5744BK1CMH2R also supports NMI and WKPU-based debug entry during low-power modes, enabling post-mortem analysis after wake-up events.
