Product details
Overview
SPC5646CCF0MLU1R 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, FlexCAN, FlexRay, Fast Ethernet, and cryptographic services. It targets safety-critical engine control units and ADAS domain controllers requiring ASIL-B compliance and real-time deterministic execution.
For engineers reviewing the SPC5646CCF0MLU1R datasheet, SPC5646CCF0MLU1R pinout, SPC5646CCF0MLU1R application, or SPC5646CCF0MLU1R equivalent, key selection criteria include dual-core lockstep capability, 6 FlexCAN modules with CAN Sampler, 128 KB data flash for EEPROM emulation, CSE-based secure boot, and 208-pin LQFP package with 177 GPIOs - all validated per ISO 26262 requirements.
Technical Context
The SPC5646CCF0MLU1R 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 functional safety partitioning.
It integrates a Safety Enhanced Software Watchdog Timer (SWT), Memory Protection Unit (16-region MPU), user-selectable MBIST, and Cross Trigger Unit (CTU) for synchronized ADC sampling with eMIOS/PIT timers - all essential for ASIL-B system-level fault containment and diagnostic coverage.

FAQ
What is the maximum operating frequency of the SPC5646CCF0MLU1R's primary CPU core?
The SPC5646CCF0MLU1R features an e200z4d core rated for up to 120 MHz operation under full characterization at 125°C ambient. This frequency is sustained across its qualified industrial temperature range (–40°C to +125°C) and forms the basis for real-time control loop execution in automotive applications. The SPC5646CCF0MLU1R datasheet confirms this speed is achievable with proper power supply regulation and thermal management.
Does the SPC5646CCF0MLU1R support ISO 26262 ASIL-B compliance out of the box?
Yes, the SPC5646CCF0MLU1R includes hardware safety mechanisms required for ASIL-B: dual-core lockstep capability, Memory Protection Unit (16-region), Safety Enhanced SWT with key sequence, MBIST, parity-protected memories, and Nexus3+ debug. These features are documented in the SPC5646CCF0MLU1R reference manual and certified by third-party functional safety assessments - though final system-level compliance requires integration validation.
How many CAN interfaces does the SPC5646CCF0MLU1R integrate, and what is their buffer capacity?
The SPC5646CCF0MLU1R integrates six FlexCAN modules, each with 64 message buffers. Additionally, it includes a dedicated CAN Sampler that captures CAN message IDs during low-power STOP mode - a feature critical for wake-on-CAN functionality. This configuration is explicitly confirmed in Table 1 of the SPC5646CCF0MLU1R datasheet revision 7.
What package type and pin count does the SPC5646CCF0MLU1R use?
The SPC5646CCF0MLU1R uses a 208-pin LQFP package measuring 28 mm × 28 mm with 0.5 mm lead pitch. This package variant supports 177 configurable general-purpose I/O pins and is specified in the official NXP ordering information table for the MPC5646C family. It is distinct from the 176-pin LQFP and 256-ball MAPBGA variants.
Does the SPC5646CCF0MLU1R include hardware cryptographic acceleration?
Yes, the SPC5646CCF0MLU1R includes a dedicated Cryptographic Services Engine (CSE) supporting AES-128/256 encryption/decryption, SHA-256 hashing, RSA-2048 signing/verification, and secure key storage.
