Product details
Overview
SPC5745BBK1AVMH6 from NXP Semiconductors is a dual-core automotive microcontroller featuring a 160 MHz e200z4 CPU and an 80 MHz e200z2 CPU, 2 MB on-chip flash memory, 256 KB SRAM with end-to-end ECC, and integrated FlexCAN3 with FD support. It operates across –40°C to +105°C and targets engine control units (ECUs) requiring ASIL-B functional safety compliance.
For engineers reviewing the SPC5745BBK1AVMH6 datasheet, SPC5745BBK1AVMH6 pinout, SPC5745BBK1AVMH6 application, or SPC5745BBK1AVMH6 equivalent, key selection criteria include dual-core deterministic timing, CAN FD interface count, flash/RAM partitioning for RWW operation, and HSMv2 security module availability in this variant.
Technical Context
The SPC5745BBK1AVMH6 implements a heterogeneous dual-core architecture where the e200z4 core handles high-intensity real-time tasks (e.g., fuel injection timing) while the e200z2 manages communication stacks and diagnostics. Both cores share a crossbar switch and SMPU with 16 region descriptors for memory protection.
Its clock system integrates FMPLL, 8–40 MHz FXOSC, 32 kHz SXOSC, and 16 MHz FIRC, enabling precise timing for engine synchronization and LIN/FlexCAN message scheduling. All bus masters-including CPUs, DMA, and peripherals-generate SECDED codes over 64-bit data + 29-bit address paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5746B | 3 MB flash, 384 KB SRAM, 8 FlexCAN FD channels; no HSMv2 in base configuration | Higher memory capacity suits complex ADAS fusion modules; lacks integrated security for secure boot use cases | Select MPC5746B when firmware size exceeds 2 MB or additional CAN FD channels are required for multi-domain gateways |
| SPC5744BK0MLH6 | 1.5 MB flash, 192 KB SRAM, 6 FlexCAN FD, same dual-core frequency and package | Lower memory footprint targets cost-sensitive entry-level ECUs; reduced RWW flexibility limits OTA update concurrency | Choose SPC5744BK0MLH6 for legacy engine platforms where 2 MB flash is unnecessary and BOM cost is critical |
Compared with SPC5745BBK1AVMH6, MPC5746B offers greater memory headroom but requires external security co-processors for secure boot, while SPC5744BK0MLH6 reduces flash/SRAM capacity without altering core performance or safety architecture-making it suitable for scaled-down implementations.

FAQ
What is the maximum operating temperature range for the SPC5745BBK1AVMH6?
The SPC5745BBK1AVMH6 is qualified for operation from –40°C to +105°C ambient temperature (Ta), with junction temperature (Tj) rated up to 150°C. This specification aligns with AEC-Q100 Grade 2 requirements and supports under-hood deployment in modern gasoline and diesel engine control units. The device maintains full electrical performance and ECC functionality across this range, as validated in NXP's Rev. 6 datasheet.
Does the SPC5745BBK1AVMH6 support CAN FD, and how many interfaces are available?
Yes, the SPC5745BBK1AVMH6 supports CAN FD on all six FlexCAN modules, each capable of bit rates up to 5 Mbps in FD mode. These interfaces include dedicated message RAM, hardware acceptance filtering, and built-in loopback testing-enabling robust communication in high-bandwidth automotive networks. This capability is confirmed in Table 1 of the MPC5746C family comparison document, which explicitly lists "6 with optional CAN FD support" for MPC5745B variants like SPC5745BBK1AVMH6.
What security features does the SPC5745BBK1AVMH6 include?
The SPC5745BBK1AVMH6 integrates HSMv2 (Hardware Security Module version 2), PASS (Password and Device Security), and FCCU (Fault Collection and Control Unit). HSMv2 provides AES-128/256, SHA-256, and RSA-2048 acceleration with secure key storage; PASS enables advanced life-cycle management and censorship; FCCU monitors hardware faults and triggers safe-state transitions. These features are documented in the "Security" and "Functional Safety" sections of the MPC5746C datasheet applicable to this variant.
Is the SPC5745BBK1AVMH6 pin-compatible with other members of the SPC574x family?
No, the SPC5745BBK1AVMH6 is not universally pin-compatible across the SPC574x family. While it shares the 256-pin MAPBGA (MJ) package with MPC5746B/C variants, pin assignments differ due to peripheral count variations-e.g., MPC5746C exposes additional FlexCAN and Ethernet signals not present in SPC5745BBK1AVMH6. Board-level compatibility must be verified using NXP's official pinout diagrams for each specific orderable part number.
What development tools are supported for the SPC5745BBK1AVMH6?
The SPC5745BBK1AVMH6 is supported by NXP's S32 Design Studio IDE, S32 Configuration Tool, and compatible debug probes including the PE Micro Cyclone Pro and Lauterbach TRACE32. Evaluation is enabled via the SPC574S-DISP discovery board and SPC5745B-176LQFP evaluation kit. These tools provide full JTAG/cJTAG and Nexus Class 3+ debug access to both e200z4 and e200z2 cores, as specified in Section 6.5 of the MPC5746C datasheet.
