SPC5744BSK1AMMH2 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 memory and bus transactions. It integrates eight FlexCAN modules with CAN FD support, four DSPI interfaces, four I²C controllers, and dual-channel FlexRay for safety-critical vehicle networking applications.

For engineers reviewing the SPC5744BSK1AMMH2 datasheet, SPC5744BSK1AMMH2 pinout, SPC5744BSK1AMMH2 application, or SPC5744BSK1AMMH2 equivalent, this part supports ISO 26262 ASIL-B functional safety requirements, offers configurable I/O domains for LIN, CAN, Ethernet, and general-purpose use, and delivers deterministic real-time control in engine control units, transmission control modules, and battery management systems.

Technical Context

The SPC5744BSK1AMMH2 implements a dual-core asymmetric architecture: the high-performance e200z4 core handles complex control and signal processing tasks, while the e200z2 core manages communication stacks and peripheral offloading. Both cores operate with Variable Length Encoding (VLE) to reduce code footprint and improve cache efficiency.

Its memory subsystem includes 1.5 MB flash organized into six 256 KB blocks, 192 KB SRAM distributed across three ports, and hardware-enforced System Memory Protection Unit (SMPU) with 16 region descriptors. All bus masters-including CPUs, DMA, and peripherals-generate SECDED codes for 64-bit data + 29-bit address transactions.

FAQ

What is the maximum operating frequency of each CPU core in the SPC5744BSK1AMMH2?

The SPC5744BSK1AMMH2 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 cores support Variable Length Encoding (VLE) to optimize code density and cache utilization. These frequencies are guaranteed across the full automotive temperature range (–40°C to +125°C) under specified voltage conditions, and are documented in the official NXP datasheet Rev. 6 for the MPC5746C family, which covers the SPC5744BSK1AMMH2 as a derivative.

Does the SPC5744BSK1AMMH2 support CAN FD, and how many CAN interfaces does it include?

Yes, the SPC5744BSK1AMMH2 includes eight FlexCAN modules, all of which support CAN FD protocol with bit rates up to 5 Mbps and flexible data field lengths. This capability is confirmed in the MPC5746C family comparison table (Table 1), where SPC5744B variants are explicitly listed with "8 with optional CAN FD support (FlexCAN[0:7])". The CAN FD implementation includes hardware-based bit-rate switching and CRC computation, reducing CPU load during high-throughput communication.

What package type and pin count does the SPC5744BSK1AMMH2 use?

The SPC5744BSK1AMMH2 uses a 256-pin MAPBGA package (package code MJ), measuring 15 mm × 15 mm with 0.8 mm ball pitch. This package includes an exposed thermal pad on the underside for efficient heat dissipation in high-temperature automotive environments. Pin compatibility is verified against the official NXP pinout documentation for the MPC5744B variant in the 256 BGA configuration, confirming signal assignments including VDD_HV_A, FXOSC_IN, CAN0_TX/RX, and JTAG debug pins.

Is the SPC5744BSK1AMMH2 certified for functional safety standards?

Yes, the SPC5744BSK1AMMH2 is designed to meet ISO 26262 ASIL-B requirements. Its safety features include a Fault Collection and Control Unit (FCCU), System Memory Protection Unit (SMPU) with 16 region descriptors, end-to-end ECC with SECDED, and hardware security module (HSMv2). These capabilities are validated in NXP's safety documentation for the MPC574x family and referenced in the datasheet section "Functional Safety" (Rev. 6, p. 3).

What is the flash memory size and organization of the SPC5744BSK1AMMH2?

The SPC5744BSK1AMMH2 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) operation, allowing concurrent code execution and flash programming. Flash endurance is rated for 100,000 program/erase cycles with 20-year data retention at 125°C junction temperature-verified per NXP's flash reliability specifications.
