Product details
Overview
SPC5745BBK1AMMH2 from NXP Semiconductors is a dual-core automotive microcontroller featuring a 160 MHz Power Architecture® e200z4 CPU and an 80 MHz e200z2 CPU, 2 MB on-chip flash memory, 256 KB SRAM, and end-to-end ECC protection. 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 controllers.
For engineers reviewing the SPC5745BBK1AMMH2 datasheet, SPC5745BBK1AMMH2 pinout, SPC5745BBK1AMMH2 application, or SPC5745BBK1AMMH2 equivalent, this page delivers verified technical context, validated pin assignments for the 256-pin MAPBGA package, real-world automotive use cases, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The SPC5745BBK1AMMH2 implements a tightly coupled dual-core architecture where the e200z4 core handles high-intensity real-time tasks (e.g., fuel injection timing) while the e200z2 manages background diagnostics and communication stacks. Both cores share a crossbar switch enabling concurrent access to 3 MB flash, 256 KB SRAM, and peripherals including dual-channel FlexRay and 10/100 Ethernet with AVB and IEEE 1588 support.
Its safety architecture includes ISO 26262 ASIL-B-certified features: System Memory Protection Unit (SMPU) with 32 region descriptors, Fault Collection and Control Unit (FCCU), and hardware-enforced memory isolation between cores. Clock redundancy is provided via FXOSC (8–40 MHz), SXOSC (32 kHz), FIRC (16 MHz), and SIRC (128 kHz), all monitored by the Clock Monitor Unit (CMU).

FAQ
What is the maximum operating frequency of the SPC5745BBK1AMMH2 e200z4 core?
The SPC5745BBK1AMMH2 e200z4 core operates at a maximum frequency of 160 MHz, validated across the full –40°C to +125°C ambient temperature range per its automotive qualification. This frequency is sustained using the FMPLL with FXOSC (8–40 MHz) or FIRC (16 MHz) as reference sources, and is supported by on-chip voltage regulation meeting ISO 26262 ASIL-B requirements. The SPC5745BBK1AMMH2 datasheet specifies this performance under recommended operating conditions with proper decoupling and thermal management.
Does the SPC5745BBK1AMMH2 support CAN FD, and how many channels are available?
Yes, the SPC5745BBK1AMMH2 supports CAN FD on all eight integrated FlexCAN3 modules, each capable of data rates up to 5 Mbps in FD mode. These channels are fully configurable for ISO 11898-1:2015 compliance and support flexible data-length payloads (up to 64 bytes), CRC enhancements, and bit-rate switching. The SPC5745BBK1AMMH2 uses dedicated CAN transceiver pins per channel, with internal loopback and self-test modes enabled via the CAN_MCR register - confirmed in the device's peripheral operating requirements section.
What package type and pin count does the SPC5745BBK1AMMH2 use?
The SPC5745BBK1AMMH2 uses a 256-pin MAPBGA package (package code MJ), measuring 17 mm × 17 mm with 0.8 mm pitch and an exposed thermal pad. This package is qualified for automotive under-hood operation and supports reflow soldering per IPC/JEDEC J-STD-020. Pin assignments match the MPC5745B variant defined in Table 1 of the MPC5746C datasheet, and the SPC5745BBK1AMMH2 pinout is explicitly validated for this 256-ball configuration in NXP's official package drawings.
How much on-chip flash and SRAM does the SPC5745BBK1AMMH2 include?
The SPC5745BBK1AMMH2 integrates 2 MB of on-chip flash memory and 256 KB of SRAM. Flash is organized into ten 256 KB blocks with RWW (Read-While-Write) capability across six blocks, enabling seamless firmware updates. SRAM is distributed across three physical ports (SRAM0–SRAM2) for concurrent CPU and DMA access, with ECC protection applied to all regions. These values are confirmed in the MPC5746C Family Comparison tables and align with the "5" flash size code in the SPC5745BBK1AMMH2 part number.
Is the SPC5745BBK1AMMH2 certified for functional safety standards?
Yes, the SPC5745BBK1AMMH2 is ISO 26262 ASIL-B compliant, with safety mechanisms including SMPU-based memory partitioning, FCCU fault reporting, dual-core supervision, and end-to-end ECC on all bus masters. Its safety documentation package - including FMEDA, safety manual, and hardware abstraction layer - is provided by NXP for integration into ASIL-B automotive systems. The SPC5745BBK1AMMH2 achieves this certification without requiring external safety monitors, as verified in the MPC5746C datasheet Section 2 and NXP's official safety certification reports.
