The ARM Cortex-M family are ARM microprocessor cores that are designed for use in microcontrollers, ASICs, ASSPs, FPGAs, and SoCs.Cortex-M cores are commonly used as dedicated microcontroller chips, but also are "hidden" inside of SoC chips as power management controllers, I/O controllers, system controllers, touch screen controllers, smart battery controllers, and sensor controllers.

The M3's Unified Memory Architecture (UMA) is similar to the M2 generation; M3 SoCs use 6,400 MT/s LPDDR5 SDRAM. As with prior M series SoCs, this serves as both RAM and video RAM. The M3 has 8 memory controllers, the M3 Pro has 12 and the M3 Max has 32. Each controller is 16-bits wide and is capable of accessing up to 4 GiB of memory. [14]
