Product details
Overview
SPC5646CCF0VLT1R 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 units requiring ASIL-B/D compliance.
For engineers reviewing the SPC5646CCF0VLT1R datasheet, SPC5646CCF0VLT1R pinout, SPC5646CCF0VLT1R application, or SPC5646CCF0VLT1R equivalent, key selection criteria include dual-core deterministic timing, integrated Ethernet/FlexRay for domain controller architectures, CSE-based secure boot, and 208-pin LQFP package with 177 GPIOs supporting automotive I/O voltage domains (3.3 V/5 V).
Technical Context
The SPC5646CCF0VLT1R 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.
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 software partitioning and time-triggered execution.
