Product details
Overview
SPC5646CCF0MLT1R 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 requiring deterministic real-time performance, ASIL-B compliance, and secure boot.
For engineers reviewing the SPC5646CCF0MLT1R datasheet, SPC5646CCF0MLT1R pinout, SPC5646CCF0MLT1R application, or SPC5646CCF0MLT1R equivalent, key selection criteria include dual-core timing isolation, 6 FlexCAN modules with CAN Sampler, 128 KB data flash for EEPROM emulation, 177 GPIOs in LQFP-176 package, and CSE-based secure firmware update capability.
Technical Context
The SPC5646CCF0MLT1R 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 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 Boot Assist Module (BAM) with VLE code execution - all aligned with ISO 26262 ASIL-B functional safety requirements for powertrain applications.

How many CAN interfaces does the SPC5646CCF0MLT1R include, and what is the CAN Sampler feature?
The SPC5646CCF0MLT1R includes six FlexCAN modules, each with 64 message buffers. Its CAN Sampler captures CAN message identifiers during low-power STOP/STANDBY modes without waking the full CPU - enabling wake-on-CAN functionality while minimizing current draw. This feature is implemented in hardware and requires no software polling, making the SPC5646CCF0MLT1R ideal for always-on network gateways and battery-sensitive modules.
What package type and pin count does the SPC5646CCF0MLT1R use?
The SPC5646CCF0MLT1R uses a 176-pin LQFP package measuring 24 mm × 24 mm with 0.5 mm lead pitch. It provides 177 configurable GPIOs, segregated into voltage domains (VDD_HV_A/B, VDD_LV) and dedicated analog supplies (VDD_HV_ADC0/ADC1) to meet automotive EMC and signal integrity requirements. This package is pin-compatible with other MPC5646C variants in the same LQFP-176 footprint.
Is the SPC5646CCF0MLT1R qualified for automotive safety standards like ISO 26262?
Yes, the SPC5646CCF0MLT1R is designed to support ASIL-B compliance per ISO 26262. It includes hardware safety mechanisms such as a Safety Enhanced Software Watchdog Timer (SWT), 16-region Memory Protection Unit (MPU), error-correcting SRAM, dual-core interrupt routing, and lockstep-capable peripherals. While the SPC5646CCF0MLT1R itself is not certified, its architecture and built-in features enable system-level ASIL-B implementation when used with appropriate safety software and development processes.
