Product details
Overview
SPC5646CCF0VMJ1R 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 powertrain and chassis control systems requiring ASIL-B compliance and real-time deterministic execution.
For engineers reviewing the SPC5646CCF0VMJ1R datasheet, SPC5646CCF0VMJ1R pinout, SPC5646CCF0VMJ1R application, or SPC5646CCF0VMJ1R equivalent, key selection criteria include dual-core lockstep capability, 6 FlexCAN modules with CAN Sampler, 128-message-buffer FlexRay, FEC for vehicle networking, and CSE for secure boot and firmware authentication.
Technical Context
The SPC5646CCF0VMJ1R 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), and Cross Trigger Unit (CTU) for synchronized ADC sampling with eMIOS/PIT timers - all essential for ISO 26262-compliant automotive software stacks.
