Cortex-M55 is an ultra-low-power ARM microarchitecture designed by ARM Holdings for microcontrollers and embedded subsystems. This microarchitecture is designed as a synthesizable IP core and is sold to other semiconductor companies to be implemented in their own chips. The Cortex-M55, which implemented the ARMv8.1-M ISA, is an ultra-low-power core which is often found in microcontrllers, low-power chips, and in the embedded subsystems of more powerful chips.
