Product type
Microcontrollers (MCUs) are compact integrated circuits designed to govern specific operations in embedded systems. They typically consist of a processor core, memory, and programmable input/output peripherals, all integrated into a single chip. MCUs are commonly made from silicon and are designed to execute a set of instructions to perform various tasks efficiently.
| Architecture | 8-bit, 16-bit, or 32-bit |
| Operating voltage | 1.8V to 5.5V |
| Flash memory size | From a few kilobytes to several megabytes |
| RAM size | Typically from 128 bytes to several kilobytes |
| Clock speed | From a few MHz to over 200 MHz |
| I/O pins | From 8 to over 100 pins |
When selecting a microcontroller, consider the specific application requirements such as processing power, memory size, and I/O capabilities. It is also important to specify the desired architecture (8-bit, 16-bit, or 32-bit), operating voltage, and any necessary communication protocols. Buyers should inquire about available development tools and support, as well as the availability of certifications for safety-critical applications.
