Product details
Overview
SPC5646CCF0VLU1R 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, FEC Ethernet, and CSE cryptographic engine. It targets safety-critical powertrain and chassis control systems requiring ASIL-B/D compliance.
For engineers reviewing the SPC5646CCF0VLU1R datasheet, SPC5646CCF0VLU1R pinout, SPC5646CCF0VLU1R application, or SPC5646CCF0VLU1R equivalent, key selection factors include dual-core deterministic timing, hardware safety features (SWT, MPU, ECSM), automotive-grade I/O (177-pin LQFP), and integrated communication stacks (CAN FD-capable FlexCAN, LINFlexD, I2C, DSPI).
Technical Context
The SPC5646CCF0VLU1R implements a crossbar switch architecture enabling concurrent access to flash, SRAM, and peripherals by both e200z4d and e200z0h cores. Its dual-core INTC routes interrupt sources selectively or concurrently to either core, supporting asymmetric multiprocessing.
It integrates a dedicated Cross Trigger Unit (CTU) for precise ADC-timer synchronization, FMPLL with frequency modulation for EMI reduction, and a Safety Enhanced SWT with keyed access-critical for ISO 26262-compliant software execution monitoring.
