Dual-core crossover MCU for real-time and application processing
The NXP MIMXRT1166XVM5A is a 32-bit dual-core crossover microcontroller from the i.MX RT1166 series, pairing an ARM Cortex-M7 core running at 500 MHz with a Cortex-M4 core at 240 MHz. This asymmetric architecture lets a single chip handle both deterministic control loops on the M4 and higher-level application processing or communications on the M7, without a separate host processor. The 1M×8 on-chip SRAM provides working memory for both cores, while program storage is external — the part boots from off-chip Flash or parallel NOR.
The MIMXRT1166XVM5A is Active and ROHS3 compliant. No last-time-buy notice or successor part exists.
