Product details
Overview
SPC5645CF0MLU1 from NXP Semiconductors is a dual-core automotive microcontroller featuring an e200z4d CPU (up to 120 MHz) and e200z0h CPU (up to 80 MHz), 3 MB on-chip flash, 256 KB SRAM, and integrated FlexCAN, DSPI, LINFlexD, Ethernet (FEC), and Cryptographic Services Engine (CSE). It targets engine control units (ECUs) requiring ASIL-B functional safety compliance and real-time deterministic execution.
For engineers reviewing the SPC5645CF0MLU1 datasheet, SPC5645CF0MLU1 pinout, SPC5645CF0MLU1 application, or SPC5645CF0MLU1 equivalent, key selection criteria include dual-core timing isolation, 6 FlexCAN modules with CAN Sampler, 100 Mbps Fast Ethernet support, CSE-based secure boot, and 256-ball MAPBGA (17 mm × 17 mm) package compatibility with automotive PCB layout constraints.
Technical Context
The SPC5645CF0MLU1 implements a crossbar switch architecture enabling concurrent access to flash, SRAM, and peripherals by both e200z4d and e200z0h cores. Its Dual-core Interrupt Controller (INTC) routes interrupt sources selectively to either core or both, supporting asymmetric multiprocessing and safety partitioning.
It integrates a Safety Enhanced Software Watchdog Timer (SWT), Memory Protection Unit (16-region MPU), and Boot Assist Module (BAM) with VLE code for secure startup. The Cross Trigger Unit (CTU) synchronizes ADC conversions with eMIOS timer events, enabling precise sensor sampling in closed-loop control systems.

FAQ
What is the maximum operating frequency of the SPC5645CF0MLU1's primary CPU core?
The SPC5645CF0MLU1 features an e200z4d core rated for up to 120 MHz operation under AEC-Q100 Grade 1 conditions (−40°C to +125°C ambient). This frequency is achievable with proper power supply decoupling, thermal management, and FMPLL configuration per the reference manual. The e200z0h secondary core operates up to 80 MHz, or at half-system frequency when the e200z4d runs above 80 MHz.
Does the SPC5645CF0MLU1 support IEEE 802.3 100BASE-TX Ethernet?
Yes, the SPC5645CF0MLU1 integrates a Fast Ethernet Controller (FEC) compliant with IEEE 802.3 for both 10 Mbps and 100 Mbps operation. It supports MII physical layer interface, full-duplex mode, and hardware checksum offload. External PHY selection and proper PCB layout (impedance-controlled traces, separation from noisy digital nets) are required for reliable 100BASE-TX implementation.
How many CAN interfaces does the SPC5645CF0MLU1 include, and what is their buffer capacity?
The SPC5645CF0MLU1 includes six independent FlexCAN modules, each with 64 message buffers. These support CAN 2.0A/B protocols and feature a dedicated CAN Sampler that captures message IDs during low-power STOP mode-enabling selective wake-up without full CAN controller initialization. All six modules are accessible in the 256-ball MAPBGA package.
Is the SPC5645CF0MLU1 qualified for automotive applications, and what is its temperature grade?
Yes, the SPC5645CF0MLU1 is AEC-Q100 qualified for automotive use and rated for Grade 1 operation (−40°C to +125°C junction temperature). It meets ISO 26262 requirements for ASIL-B safety integrity level when used with appropriate system-level mechanisms, including its built-in SWT, MPU, and Nexus3+ debug trace capabilities.
What security features are implemented in the SPC5645CF0MLU1's Cryptographic Services Engine (CSE)?
The SPC5645CF0MLU1's CSE provides hardware-accelerated AES-128/256 encryption/decryption, SHA-256 hashing, and RSA-2048 signature generation/verification. It supports secure boot authentication, key provisioning via OTP fuses, and runtime encryption of CAN/FlexRay frames. CSE operation is isolated from the main CPU cores and managed through dedicated registers accessible only in supervisor mode.
