Product details
Overview
SPC5745BBK1AMMH6 from NXP Semiconductors is a dual-core Power Architecture® automotive microcontroller featuring a 160 MHz 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 SPC5745BBK1AMMH6 datasheet, SPC5745BBK1AMMH6 pinout, SPC5745BBK1AMMH6 application, or SPC5745BBK1AMMH6 equivalent, this page delivers verified technical context, validated pin mapping for the 256-pin MAPBGA package, real-world use cases in powertrain systems, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The SPC5745BBK1AMMH6 implements a dual-core asymmetric architecture where the e200z4 core handles high-integrity real-time tasks (e.g., torque calculation, fuel injection timing) while the e200z2 core manages communication stacks and diagnostics. Both cores share a crossbar switch and SMPU with 32 region descriptors for memory isolation.
Its clock system includes an 8–40 MHz FXOSC, 32 kHz SXOSC, 16 MHz FIRC, and FMPLL supporting frequency-modulated operation for EMI reduction. All bus masters-including CPUs, DMA, and peripherals-generate SECDED codes covering 64-bit data and 29-bit addresses for full end-to-end ECC coverage.

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, 324-pin MAPBGA - adds one additional e200z2 core and larger memory footprint | Targeted at higher-complexity powertrain applications requiring extended firmware features and larger diagnostic log buffers | Select MPC5746C when >2 MB flash or >256 KB SRAM is required; not pin-compatible due to 324-ball vs. 256-ball layout |
| SPC5744BK0MLL6 | 1.5 MB flash, 192 KB SRAM, 176-pin LQFP-EP - lacks HSMv2 and has reduced FlexCAN count (6 vs. 8) | Suitable for cost-sensitive entry-level ECUs where CAN FD bandwidth and cryptographic security are not mandatory | Choose SPC5744BK0MLL6 for space-constrained LQFP designs with lower functional safety scope; requires PCB redesign |
Compared with MPC5746C and SPC5744BK0MLL6, the SPC5745BBK1AMMH6 delivers optimal balance of ASIL-B compliance, CAN FD bandwidth, and 256-ball BGA manufacturability - making it the preferred choice for mid-tier powertrain ECUs requiring field-upgradable firmware and hardware-enforced security without over-provisioning memory.

FAQ
What is the maximum operating frequency of the SPC5745BBK1AMMH6 e200z4 core?
The SPC5745BBK1AMMH6 e200z4 core operates at a maximum frequency of 160 MHz, validated across the full –40°C to +125°C ambient temperature range per NXP's recommended operating conditions. This frequency is sustained using the FMPLL with an 8–40 MHz external crystal or 16 MHz FIRC source, and is supported by the on-chip voltage regulator delivering 1.2–1.32 V to the VDD_LV supply pins. The SPC5745BBK1AMMH6 maintains timing integrity under these conditions with full end-to-end ECC enabled.
Does the SPC5745BBK1AMMH6 support CAN FD, and how many interfaces are available?
Yes, the SPC5745BBK1AMMH6 supports CAN FD on all eight integrated FlexCAN3 modules, each capable of data phase bit rates up to 5 Mbps. These interfaces are fully configurable for ISO 11898-1 compliant operation and include built-in message filtering, FIFO buffering, and error confinement. The SPC5745BBK1AMMH6 implements CAN FD without requiring external transceivers - physical layer drivers are integrated, and signal routing follows NXP's validated layout guidelines for EMC robustness.
What package type and pin count does the SPC5745BBK1AMMH6 use?
The SPC5745BBK1AMMH6 uses a 256-pin MAPBGA package (package code MJ), with 14 mm × 14 mm body size and 0.8 mm ball pitch. This package is thermally optimized for automotive under-hood environments and includes dedicated power/ground ball arrays for low-impedance supply distribution. Pin assignments match NXP's official SPC5745B pinout documentation, and the package supports standard reflow profiles for lead-free assembly. The SPC5745BBK1AMMH6 is not compatible with 176-pin LQFP or 324-pin BGA footprints.
How does the SPC5745BBK1AMMH6 implement functional safety per ISO 26262?
The SPC5745BBK1AMMH6 achieves ISO 26262 ASIL-B compliance through hardware-enforced mechanisms: end-to-end ECC on all memory and bus transactions, System Memory Protection Unit (SMPU) with 32 configurable regions, Fault Collection and Control Unit (FCCU) for error logging and safe state triggering, and hardware watchdog timers (SWT, PIT-RTI). These features are validated in NXP's safety manual and supported by diagnostic software libraries. The SPC5745BBK1AMMH6 does not require external safety monitors to meet ASIL-B requirements for powertrain control functions.
What is the flash memory configuration of the SPC5745BBK1AMMH6?
The SPC5745BBK1AMMH6 contains 2 MB of on-chip flash memory organized into ten 256 KB blocks, with flexible RWW (Read-While-Write) partitioning enabling concurrent execution and firmware updates. Flash programming is supported via Boot Assist Flash (BAF) over SCI or JTAG, and the triple-port flash controller allows simultaneous read, program, and erase operations. The SPC5745BBK1AMMH6 supports EEPROM emulation up to 64 KB using dedicated data flash sectors, and flash endurance is rated for 100,000 program/erase cycles with 20-year data retention at 125°C junction temperature.
