The following is a rough guide, the reality is considerably more complicated.

Class	Manufacturer	Architecture	Clock	Wikipedia	Notes
AVR	Microchip (was Atmel)	8-bit AVR	1.6 to 32 MHz	AVR microcontrollers	ATmega328, ATtiny
PIC	Microchip	8-bit to 32-bit PIC	0 to 200 MHz	PIC microcontrollers
STM32	ST Micro	32-bit ARM Cortex-M0+	0 to 48 MHz	STM32
SAM	Microchip (was Atmel)	32-bit ARM Cortex-M0+	0 to 48 MHz	Atmel ARM-based processors	e.g. ATSAMD21G18
RP2040	Raspberry Pi	32-bit ARM Cortex-M0+	0 to 48 MHz	RP2040
ESP32	Espressif Systems	32-bit Xtensa LX6 / RISC-V	160 or 240 MHz	ESP32	replaces ESP8266; integrated Wi-Fi and dual-mode Bluetooth
MSP430	Texas Instruments	16-bit MSP430	0 to 25 MHz	TI MSP430	TI range
nRF	Nordic Semiconductor	32-bit ARM Cortex	16 to 70 MHz	Nordic Semiconductor
