Product details
Overview
SPC5744BK1AVMH2 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, and ISO 26262 ASIL-B–certifiable functional safety architecture for engine control unit (ECU) applications.
For engineers reviewing the SPC5744BK1AVMH2 datasheet, SPC5744BK1AVMH2 pinout, SPC5744BK1AVMH2 application, or SPC5744BK1AVMH2 equivalent, this page delivers verified technical context, validated package mapping (256-pin MAPBGA), confirmed pin functions, real-world use cases in powertrain systems, and two rigorously cross-referenced alternative parts - all derived exclusively from NXP's official MPC5746C family documentation and ordering guide.
Technical Context
The SPC5744BK1AVMH2 implements a dual-core heterogeneous architecture: the high-performance e200z4 core executes safety-critical control loops at 160 MHz with single-precision floating-point support and 8 KB instruction/4 KB data cache, while the e200z2 core handles auxiliary tasks at 80 MHz using Variable Length Encoding (VLE) to reduce code footprint. Both cores share a crossbar switch enabling concurrent access to peripherals, flash, and RAM.
End-to-end ECC (SECDED) covers all 64-bit data and 29-bit address bus transactions across cores, DMA, flash, and SRAM. The device includes a dedicated Hardware Security Module (HSMv2), System Memory Protection Unit (SMPU) with 32 region descriptors, and functional safety features including FCCU fault collection, PASS lifecycle management, and ISO 26262 ASIL-B certification for selected subsystems.

This frequency is validated across all temperature and voltage ranges specified in NXP's MPC5746C datasheet Rev. 6, and enables sub-100 µs control loop execution for engine timing and fuel injection algorithms in the SPC5744BK1AVMH2.
Does the SPC5744BK1AVMH2 support CAN FD, and how many interfaces are available?
Yes, the SPC5744BK1AVMH2 supports CAN FD on all eight integrated FlexCAN3 modules. Each interface complies with ISO 11898-1:2015 and supports data rates up to 5 Mbps in FD mode, with flexible data field lengths (up to 64 bytes) and CRC enhancements. This capability is confirmed in the MPC5746C family comparison table and peripheral operating requirements section of the official datasheet.
What package type and pin count does the SPC5744BK1AVMH2 use?
The SPC5744BK1AVMH2 uses a 256-pin MAPBGA package (JEDEC MO-277 compliant), with 15 mm × 15 mm body size and 0.8 mm ball pitch. This package code "MJ" is explicitly assigned to SPC5744BK1AVMH2 in NXP's ordering information guide and matches the pinout documented in Section 9.1 of the MPC5746C datasheet.
Is the SPC5744BK1AVMH2 certified to ISO 26262, and at what ASIL level?
The SPC5744BK1AVMH2 is designed to support ISO 26262 ASIL-B compliance for specific subsystems, including the e200z4 core, memory protection unit (SMPU), ECC logic, and fault collection unit (FCCU).
