Product details
Overview
SPC5645SF1VLTR 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, DSPI, LINFlexD, FEC Ethernet, and CSE cryptographic engine - deployed in engine control units, transmission controllers, and ADAS domain controllers.
For engineers reviewing the SPC5645SF1VLTR datasheet, SPC5645SF1VLTR pinout, SPC5645SF1VLTR application, or SPC5645SF1VLTR equivalent, key selection criteria include dual-core deterministic timing, ASIL-B capable safety architecture, 6 FlexCAN modules with CAN Sampler, 100 Mbps Fast Ethernet support, and 256-ball MAPBGA package with 199 configurable GPIOs.
Technical Context
The SPC5645SF1VLTR implements a crossbar switch architecture enabling concurrent access to flash, SRAM, and peripherals by multiple bus masters including both e200z4d and e200z0h cores. Its Dual-core Interrupt Controller (INTC) routes interrupt sources selectively to either core or both, supporting asymmetric multiprocessing and real-time partitioning.
It integrates a Safety Enhanced Software Watchdog Timer (SWT), Memory Protection Unit (16-region MPU), Cross Trigger Unit (CTU) for ADC-timer synchronization, and Boot Assist Module (BAM) with VLE code execution - all aligned with ISO 26262 functional safety requirements for automotive ASIL-B systems.
