![]() ![]() Though 8-bit microcontrollers were very popular in the past, Cortex-M has slowly been chipping away at the 8-bit market as the prices of low-end Cortex-M chips have moved downward. 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 sensors controllers. The ARM Cortex-M family are ARM microprocessor cores which are designed for use in microcontrollers, ASICs, ASSPs, FPGAs, and SoCs. ![]() The Cortex-M4 / M7 / M33 / M35P cores have an FPU silicon option, and when included in the silicon these cores are known as 'Cortex-Mx with FPU' or 'Cortex-MxF', where 'x' is the core number. The cores consist of the Cortex-M0, Cortex-M0+, Cortex-M1, Cortex-M3, Cortex-M4, Cortex-M7, Cortex-M23, Cortex-M33, Cortex-M35P. They are intended for microcontroller use, and have been shipped in tens of billions of devices. ![]() The ARM Cortex-M is a group of 32-bitRISCARM processor cores licensed by Arm Holdings. 24 MHz ARM Cortex-M3 microcontroller with 16 KBflash memory, 4 KB RAM. ![]()
