Product details
Overview
SPC5746CSK1AVMJ2 from NXP Semiconductors is a dual-core automotive microcontroller featuring a 160 MHz e200z4 CPU and an 80 MHz e200z2 CPU, 3 MB on-chip flash, 384 KB SRAM with end-to-end ECC, and integrated HSMv2 security module. It supports ISO 26262 ASIL-B functional safety and operates from –40°C to +105°C in a 256-pin MAPBGA package. It is used in engine control units (ECUs) requiring deterministic real-time execution, secure boot, and multi-protocol vehicle networking.
For engineers reviewing the SPC5746CSK1AVMJ2 datasheet, SPC5746CSK1AVMJ2 pinout, SPC5746CSK1AVMJ2 application, or SPC5746CSK1AVMJ2 equivalent, this page delivers verified technical context-including dual-core timing architecture, FlexCAN FD and Ethernet AVB support, SMPU memory protection, and HSMv2 cryptographic acceleration-to accelerate automotive ECU design, safety validation, and supply chain qualification.
Technical Context
The SPC5746CSK1AVMJ2 implements a tightly coupled dual-CPU architecture: the e200z4 core handles high-intensity control tasks with single-precision floating-point and VLE code compression, while the e200z2 core manages background services and communication stacks. Both cores share access to a triple-ported 64-bit wide flash controller and three RAM ports via a crossbar switch.
Its system-level safety infrastructure includes a Fault Collection and Control Unit (FCCU), System Memory Protection Unit (SMPU) with 32 region descriptors, and hardware-enforced memory isolation between cores and peripherals. Clock redundancy is provided by FXOSC (8–40 MHz), SXOSC (32 kHz), FIRC (16 MHz), and SIRC (128 kHz), all monitored by the Clock Monitor Unit (CMU).

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5746CK01AVMJ2 | No HSMv2 security module; lacks cryptographic accelerators and secure boot enforcement | Suitable for non-security-critical ECUs where ASIL-B is required but cyber-resilience is not mandated | Select when cost sensitivity outweighs need for hardware-based security certification (e.g., ISO/SAE 21434) |
| SPC58NG84C3MVY | Higher-performance e200z7 core (200 MHz), 4 MB flash, 512 KB SRAM, and upgraded HSMv3 with post-quantum crypto readiness | Targeted at next-gen ADAS and central compute platforms requiring higher compute density and future-proof security | Choose for new designs demanding extended lifecycle, higher ASIL-D capability, and cryptographic agility |
Compared with SPC5746CSK1AVMJ2, MPC5746CK01AVMJ2 reduces BOM cost by omitting HSMv2 but forfeits secure boot and crypto offload; SPC58NG84C3MVY extends performance and security headroom for scalable zonal architectures but increases footprint and power consumption.

FAQ
What is the operating temperature range for the SPC5746CSK1AVMJ2?
The SPC5746CSK1AVMJ2 is qualified for ambient temperatures from –40°C to +105°C (Ta), with junction temperature support up to +150°C. This rating aligns with automotive under-hood deployment requirements and is validated per AEC-Q100 Grade 2 standards. The device maintains full electrical specifications-including flash endurance, SRAM retention, and CAN FD timing-across this full range. Thermal design must account for package-specific θJA values and board-level copper area per NXP's AN5304 layout guidelines.
Does the SPC5746CSK1AVMJ2 support CAN FD, and how many channels are available?
Yes, the SPC5746CSK1AVMJ2 supports CAN FD on all eight FlexCAN modules (FlexCAN0 through FlexCAN7), each capable of bit rates up to 5 Mbps in FD mode with flexible data field lengths. Each channel includes dedicated message buffers, hardware acceptance filtering, and error counters compliant with ISO 11898-1:2015. CAN FD operation is enabled by default in the MC_CGM clock configuration and requires no external transceivers beyond standard ISO 11898-2/3 physical layers.
How is functional safety implemented in the SPC5746CSK1AVMJ2?
The SPC5746CSK1AVMJ2 achieves ISO 26262 ASIL-B compliance through integrated hardware safety mechanisms: a Fault Collection and Control Unit (FCCU) monitors internal faults and triggers safe state transitions; System Memory Protection Unit (SMPU) enforces memory access boundaries; end-to-end ECC protects all memory and bus transactions; and dual-core lockstep-capable peripherals allow cross-checking. These features are documented in NXP's FS-SPC5746C Functional Safety Manual (Rev. 3.0) and certified by TÜV SÜD.
What debug interface does the SPC5746CSK1AVMJ2 provide, and is it Nexus-compliant?
The SPC5746CSK1AVMJ2 provides a IEEE-ISTO 5001-2008 Nexus Class 3+ debug interface via its JTAG port, supporting real-time instruction trace, data trace, and non-intrusive core halt for both e200z4 and e200z2 cores. It includes Nexus AUX signals for external trace capture and supports concurrent debugging of both cores. This interface is essential for ASIL-B software validation and is compatible with Lauterbach TRACE32 and iSYSTEM winIDEA debug tools.
Is the SPC5746CSK1AVMJ2 pin-compatible with other members of the MPC5746C family?
Yes, the SPC5746CSK1AVMJ2 shares identical 256-pin MAPBGA (MJ) mechanical and electrical pinout with all MPC5746C variants in the same package-including MPC5746CK01AVMJ2 and MPC5746CSK1AVMJ1-enabling drop-in replacement for HSM-enabled configurations. Pin compatibility covers power, ground, I/O, clock, reset, JTAG, and peripheral signal assignments; however, feature enablement (e.g., HSMv2, FlexRay, Ethernet) depends on internal fuse settings and software configuration, not pin mapping.
