Product details
Overview
SPC5745BFK1AVMH2 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, 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. It targets engine control units (ECUs) requiring deterministic real-time performance and secure firmware execution.
For engineers reviewing the SPC5745BFK1AVMH2 datasheet, SPC5745BFK1AVMH2 pinout, SPC5745BFK1AVMH2 application, or SPC5745BFK1AVMH2 equivalent, key selection criteria include dual-core timing isolation, CAN FD bandwidth for high-speed diagnostics, HSMv2 cryptographic acceleration, 2 MB flash partitioning for RWW operation, and qualification for -40°C to +125°C ambient operation in automotive powertrain systems.
Technical Context
The SPC5745BFK1AVMH2 implements a heterogeneous dual-core architecture where the e200z4 core handles high-intensity control tasks (e.g., fuel injection timing) and the e200z2 core manages communication stacks and diagnostics. Both cores operate under independent clock domains managed by FMPLL and supported by FIRC/SIRC/SXOSC/ FXOSC sources.
Memory subsystem includes triple-ported 2 MB flash with three page buffers and 256 KB SRAM distributed across two RAM ports, all protected by SECDED ECC. Peripheral access is coordinated via a crossbar switch supporting concurrent DMA transfers, eMIOS timer I/O, and synchronized ADC conversions triggered by eMIOS or PIT events.

FAQ
What is the maximum operating frequency of each CPU core in the SPC5745BFK1AVMH2?
The SPC5745BFK1AVMH2 features two independent CPU cores: the e200z4 core operates at up to 160 MHz, and the e200z2 core operates at up to 80 MHz. These frequencies are guaranteed under the recommended operating conditions of –40°C to +125°C ambient temperature and specified supply voltages. The SPC5745BFK1AVMH2 datasheet confirms these values in the "Maximum Operating Frequency" row of the family comparison table.
Does the SPC5745BFK1AVMH2 support CAN FD, and how many interfaces are available?
Yes, the SPC5745BFK1AVMH2 supports CAN FD across all eight integrated FlexCAN3 modules. Each interface is capable of data rates up to 5 Mbps in FD mode, with full protocol compliance including ISO 11898-1:2015. This capability is explicitly confirmed in the MPC5746C datasheet family comparison table, which lists "8 with optional CAN FD support" for the MPC5745C variant - and SPC5745BFK1AVMH2 is the automotive-qualified MPC5745C derivative.
What is the flash memory size and organization of the SPC5745BFK1AVMH2?
The SPC5745BFK1AVMH2 contains 2 MB of on-chip flash memory, organized into ten 256 KB blocks (Flash blocks 0–9), with blocks 0–3 always available and blocks 4–5 available per the MPC5745 family definition. It supports Read-While-Write (RWW) operation using dedicated flash page buffers, enabling background firmware updates without halting real-time execution. This configuration is documented in Table 2 ("MPC5746C Family Comparison – NVM Memory Map 1") of the official datasheet.
Is the SPC5745BFK1AVMH2 qualified for automotive temperature ranges?
Yes, the SPC5745BFK1AVMH2 is qualified for operation from –40°C to +125°C ambient temperature (Ta), as indicated by the "M" suffix in its part number. This qualification aligns with AEC-Q100 Grade 1 requirements and is verified through extended temperature characterization. The device's thermal attributes and absolute maximum ratings tables confirm junction temperature limits up to 150°C, supporting reliable deployment in under-hood automotive environments.
Does the SPC5745BFK1AVMH2 include hardware security features for secure boot and firmware updates?
Yes, the SPC5745BFK1AVMH2 integrates HSMv2 (Hardware Security Module version 2) and PASS (Password and Device Security) subsystems. These provide cryptographic acceleration (AES-128, SHA-256), secure key storage, secure boot verification, and life-cycle management - all required for UNECE R155-compliant cybersecurity management systems. The datasheet explicitly lists HSMv2 as an optional feature for MPC5745C, and SPC5745BFK1AVMH2 includes it as standard per its "B" security designation.
