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.

5nm (common for SoCs using Cortex-A510) No N/A 32 or 64 KB each Configurable, typically 128 KB to 512 KB N/A Typically paired with Cortex-A710 in configurations (e.g., 1+3) Not explicitly stated, but performance uplift of 35% over A55 Up to 2.85 GHz (varies by implementation) Not specified in search results Arm Holdings: Cortex-A710 May 2021
The STM32 chips are grouped into related series that are based around the same 32-bit ARM processor core: Cortex-M0, Cortex-M0+, Cortex-M3, Cortex-M4, Cortex-M7, Cortex-M33. Internally, each microcontroller consists of ARM processor core(s), flash memory , static RAM , debugging interface, and various peripherals.
Implemented on Cortex-R4 and R5 processors and the Tegra 2 (Cortex-A9). VFPv3-F16 Uncommon; it supports IEEE754-2008 half-precision (16-bit) floating point as a storage format. VFPv4 or VFPv4-D32 Implemented on Cortex-A12 and A15 ARMv7 processors, Cortex-A7 optionally has VFPv4-D32 in the case of an FPU with Neon. [137]
