ARM Cortex-M

<p>The ARM Cortex-M is a group of <a href="/facts/32-bit/TDMVce8s">32-bit</a> <a href="/facts/Reduced_instruction_set_computer/aQbGM62p">RISC</a> <a href="/facts/ARM_architecture/SALsYA79">ARM</a> processor cores licensed by <a href="/facts/Arm_(company)/jqqppj7b">ARM Limited</a>.  These cores are optimized for low-cost and energy-efficient integrated circuits, which have been embedded in tens of billions of consumer devices.  Though they are most often the main component of <a href="/facts/Microcontroller/MKrnAhnm">microcontroller</a> chips, sometimes they are embedded inside other types of chips too.  The Cortex-M family consists of Cortex-M0, Cortex-M0+,[3] Cortex-M1, Cortex-M3, Cortex-M4, Cortex-M7, Cortex-M23, Cortex-M33, Cortex-M35P, Cortex-M52, Cortex-M55, Cortex-M85.  A <a href="/facts/Floating-point_unit/XWTW2AbF">floating-point unit</a> (FPU) option is available for Cortex-M4 / M7 / M33 / M35P / M52 / M55 / M85 cores, and when included in the silicon these cores are sometimes known as "Cortex-MxF", where 'x' is the core variant.
