Product details
Overview
SPC5646CCF0MMJ1 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, 64 KB data flash, FlexCAN, FlexRay, Fast Ethernet, and Cryptographic Services Engine (CSE). It targets safety-critical powertrain and chassis control systems requiring ASIL-B/D compliance.
For engineers reviewing the SPC5646CCF0MMJ1 datasheet, SPC5646CCF0MMJ1 pinout, SPC5646CCF0MMJ1 application, or SPC5646CCF0MMJ1 equivalent, key selection criteria include dual-core deterministic timing, integrated Ethernet/FlexRay for domain controller architectures, hardware security (CSE), and support for AUTOSAR-compliant real-time OS with MPU and SWT.
Technical Context
The SPC5646CCF0MMJ1 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 sources independently to either core or both, supporting asymmetric multiprocessing.
It integrates a Safety Enhanced Software Watchdog Timer (SWT), Memory Protection Unit (16-region MPU), and Cross Trigger Unit (CTU) for synchronized ADC sampling with eMIOS/PIT timers - all essential for ISO 26262-compliant functional safety implementations in automotive ECUs.

FAQ
What is the maximum operating frequency of the SPC5646CCF0MMJ1's primary CPU core?
The SPC5646CCF0MMJ1's e200z4d core operates at up to 120 MHz. This frequency is validated across the full industrial temperature range (−40°C to 125°C) and supports deterministic real-time execution for AUTOSAR-based powertrain software. The e200z0h secondary core runs at up to 80 MHz or half the system frequency when the e200z4d is above 80 MHz - a configuration managed by the MC_CGM clock generation module. SPC5646CCF0MMJ1 maintains this performance while delivering low-power STOP/HALT modes.
Does the SPC5646CCF0MMJ1 support hardware cryptographic acceleration?
Yes, the SPC5646CCF0MMJ1 integrates a Cryptographic Services Engine (CSE) supporting AES-128/256 encryption/decryption, SHA-256 hashing, RSA-2048 signature verification, and secure key storage. This enables secure boot, encrypted OTA firmware updates, and TLS offload - meeting UNECE R155/R156 cybersecurity management system (CSMS) requirements. The CSE is accessible via dedicated memory-mapped registers and operates independently of the CPU cores. SPC5646CCF0MMJ1 uses CSE to enforce hardware-rooted trust without software overhead.
What communication interfaces are integrated into the SPC5646CCF0MMJ1?
The SPC5646CCF0MMJ1 integrates six FlexCAN modules (64 message buffers each), one FlexRay controller (128 message buffers), one Fast Ethernet Controller (10/100 Mbps MII interface), eight DSPI modules, ten LINFlexD modules, and one I²C module. These interfaces support simultaneous operation via the crossbar switch, enabling domain controller architectures that aggregate CAN, LIN, FlexRay, and Ethernet traffic. SPC5646CCF0MMJ1 does not require external protocol bridges or PHYs for these functions - reducing BOM cost and PCB area.
How does the SPC5646CCF0MMJ1 meet ISO 26262 functional safety requirements?
The SPC5646CCF0MMJ1 meets ISO 26262 ASIL-D requirements through integrated safety mechanisms: a 16-region Memory Protection Unit (MPU), Safety Enhanced Software Watchdog Timer (SWT) with keyed access, FMPLL clock monitor, Nexus3+ debug with trace, and dual-core lockstep or split-task capability. Its hardware diagnostic coverage exceeds 90% for CPU, memory, and peripheral paths. SPC5646CCF0MMJ1 includes safety manuals, FMEDA reports, and certified compiler toolchains - enabling seamless integration into ASIL-D automotive ECU designs.
What package type and pin count does the SPC5646CCF0MMJ1 use?
The SPC5646CCF0MMJ1 uses a 208-pin LQFP package measuring 28 mm × 28 mm with 0.5 mm lead pitch. This package supports 177 configurable GPIOs (including analog inputs), dedicated power domains (VDD_HV_A/B, VDD_HV_ADC0/1, VDD_LV), and thermal performance rated for −40°C to 125°C ambient operation.
