12F635 is 8-Bit CMOS Microcontroller With nanoWatt Technology.

An 8-bit CMOS microcontroller refers to a microcontroller that has an 8-bit central processing unit (CPU) and utilizes complementary metal-oxide-semiconductor (CMOS) technology in its design.

CMOS technology is widely used in integrated circuits due to its low power consumption and high noise immunity characteristics. It allows for efficient use of power, making CMOS microcontrollers suitable for applications where power efficiency is crucial, such as battery-powered devices.

An 8-bit CMOS microcontroller typically includes other essential components, such as random-access memory (RAM), read-only memory (ROM) or flash memory for program storage, input/output (I/O) ports, timers, and various peripherals. These components allow the microcontroller to perform a wide range of tasks and interface with other devices.
