Product details
Overview
SPC5646CF0MLU1 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, and integrated FlexRay, CAN, Ethernet, and cryptographic services. It targets safety-critical powertrain and chassis control systems requiring ASIL-B compliance and real-time determinism.
For engineers reviewing the SPC5646CF0MLU1 datasheet, SPC5646CF0MLU1 pinout, SPC5646CF0MLU1 application, or SPC5646CF0MLU1 equivalent, key selection criteria include dual-core interrupt routing capability, 6 FlexCAN modules with CAN Sampler, 128-channel eDMA with DMAMUX, Fast Ethernet Controller (FEC), and CSE-based secure boot support - all validated for automotive ECU designs operating at 125 °C ambient.
Technical Context
The SPC5646CF0MLU1 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) supports configurable routing of 64+ interrupt sources to either core or both, with priority-based preemption.
It integrates a 32-channel eDMA controller with DMAMUX supporting 57 selectable sources, a Cross Trigger Unit (CTU) synchronizing ADC conversions with eMIOS/PIT events, and a Safety Enhanced SWT with keyed functionality - all aligned with ISO 26262 functional safety requirements for ASIL-B applications.
