Microcontrollers and PICs
A microcontroller is a complete small computer built onto a single integrated circuit. Unlike a microprocessor, which is only the central processing unit and needs external memory and support chips, a microcontroller integrates the processor core, program memory, data memory and input/output peripherals on one chip. This self-contained design makes microcontrollers ideal for embedded control: running the logic inside appliances, instruments, toys, vehicles and countless other devices that are not thought of as computers.
PICs are a well-known family of microcontrollers that became especially popular with hobbyists and in low-cost products. They span a wide range of sizes, from tiny chips with a handful of pins to more capable devices, and they include on-chip features such as timers, analog inputs and serial communication. Because they are inexpensive, widely documented and supported by free development tools, PICs are often used as a first introduction to embedded programming.
PICs sit alongside many other microcontroller families. The 8051 architecture and its derivatives, including the 80C51 and 8052, have been used in industry for decades, while development boards such as the BASIC Stamp wrap a microcontroller in an easy-to-program package for beginners. Choosing among them involves weighing processing power, memory, available peripherals, power consumption, cost and the maturity of the programming tools against the needs of the project.
Frequently asked questions
- How does a microcontroller differ from a microprocessor?
- A microcontroller combines the processor, memory and input/output on a single chip, whereas a microprocessor is only the processing unit and requires external memory and support chips.
- What is a PIC?
- A PIC is a member of a popular family of microcontrollers that integrate a processor with memory and peripherals such as timers and analog inputs, widely used in hobby and low-cost embedded projects.
- What are microcontrollers used for?
- They run the embedded control logic inside everyday devices such as appliances, instruments, vehicles and toys, handling sensing, timing and decision-making tasks.
