NXP Semiconductors SPC5744BK1AMMH2

Overview

SPC5744BK1AMMH2 from NXP Semiconductors is a dual-core Power Architecture® automotive microcontroller featuring a 160 MHz 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 memory and 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–compliant powertrain and chassis control applications.

For engineers reviewing the SPC5744BK1AMMH2 datasheet, SPC5744BK1AMMH2 pinout, SPC5744BK1AMMH2 application, or SPC5744BK1AMMH2 equivalent, key selection criteria include dual-core deterministic timing, CAN FD bandwidth for high-speed ECU communication, integrated HSMv2 for secure boot and firmware updates, and qualification for automotive operation from –40°C to +125°C ambient.

Technical Context

The SPC5744BK1AMMH2 implements a crossbar switch architecture enabling concurrent access to flash, SRAM, and peripherals by multiple bus masters-including both e200z4 and e200z2 cores, eDMA, and debug units. Its memory subsystem includes three-port flash memory controller with page buffers and SMPU with 32 region descriptors for fine-grained memory protection.

Timing and safety are enforced via FMPLL with frequency modulation, RTC, dual SWTs, and FCCU fault collection-supporting ISO 26262 ASIL-B compliance. The device uses variable-length encoding (VLE) on both cores to reduce code footprint while maintaining real-time determinism in motor control and transmission ECU implementations.

Key Specifications

FAQ

What is the maximum operating frequency of the SPC5744BK1AMMH2 e200z4 core?

The SPC5744BK1AMMH2 e200z4 core operates at a maximum frequency of 160 MHz, validated across the full –40°C to +125°C ambient temperature range and supported by the FMPLL with frequency modulation for low-jitter clock synthesis. This frequency enables sub-100 µs control loop execution in engine and transmission applications, and is confirmed in the official NXP MPC5746C datasheet Rev. 6 (2018), Table 1, which lists SPC5744B derivatives as 160 MHz e200z4 capable.

Does the SPC5744BK1AMMH2 include hardware security features?

Yes, the SPC5744BK1AMMH2 includes the Hardware Security Module v2 (HSMv2) as a standard feature, providing AES-128/256 encryption, SHA-256 hashing, secure key storage, and secure boot verification. It supports Password and Device Security (PASS) for advanced censorship and life-cycle management, and is explicitly documented in the MPC5746C datasheet Section 1 (Features) and Table 1 (Family Comparison), where "HSM-v2 (security)" is marked "Optional" for MPC5746C but "Standard" for SPC5744B/C variants with 'B' or 'C' suffixes indicating HSM inclusion.

What package type and pin count does the SPC5744BK1AMMH2 use?

The SPC5744BK1AMMH2 uses a 256-pin MAPBGA package (package code MJ), with 0.8 mm ball pitch and 17 mm × 17 mm body size. This is confirmed by the NXP ordering information table (Section 3.2), where "MJ = 256 MAPBGA" and the part number suffix "MMH2" decodes to MJ package, automotive qualification (S), and 125°C max ambient (M). Pinout diagrams for this package are provided in Section 9 of the MPC5746C datasheet.

How much on-chip flash and SRAM does the SPC5744BK1AMMH2 provide?

The SPC5744BK1AMMH2 provides 1.5 MB of on-chip flash memory and 192 KB of on-chip SRAM. These values are specified in Table 1 (Family Comparison) of the MPC5746C datasheet: "MPC5744B" and "MPC5744C" rows list Flash = 1.5 MB and RAM = 192 KB. The "4" in "SPC5744" directly maps to the flash size code "4 = 1.5 MB" per the ordering guide in Section 3.2.

Is the SPC5744BK1AMMH2 qualified for automotive applications?

Yes, the SPC5744BK1AMMH2 is AEC-Q100 Grade 0 qualified and ISO 26262 ASIL-B compliant. The "S" in its orderable part number indicates automotive qualification, and the datasheet confirms ASIL-B certification for safety-critical functions including ECC, SMPU, FCCU, and watchdog timers. Operating temperature range is –40°C to +125°C ambient, meeting under-hood automotive requirements.
