ATTINY85-20PU 20MHZ 8 Pin DIP-8 Microcontroller IC Chips

Description

The ATtiny85-20PU is an 8-bit microcontroller integrated circuit (IC) chip, often referred to as a microcontroller unit (MCU), from the ATtiny series produced by Atmel (now part of Microchip Technology). Here’s a description of its key features and functions:

**1. 8-Bit Microcontroller:** The ATtiny85 is an 8-bit microcontroller, which means it processes data in 8-bit chunks. It is a small and low-power MCU suitable for various embedded systems and projects.

**2. ATtiny Series:** The ATtiny series of microcontrollers is known for its compact size and low power consumption, making it ideal for applications where space and energy efficiency are important.

**3. High Clock Speed:** The “20MHz” designation indicates that the ATtiny85-20PU operates with a maximum clock speed of 20 megahertz. This clock speed determines the execution speed of instructions and the overall processing capability of the MCU.

**4. Flash Memory:** The ATtiny85-20PU typically features a certain amount of flash memory for program storage. You can write your program code into this memory, and the MCU executes the code from there.

**5. EEPROM:** It also includes electrically erasable programmable read-only memory (EEPROM) for storing data that needs to be retained even when the power is turned off.

**6. SRAM:** The ATtiny85 has static random-access memory (SRAM) for storing data temporarily during program execution.

**7. I/O Pins:** The ATtiny85-20PU comes with a set of general-purpose input/output (I/O) pins. The number and capabilities of these pins can vary among microcontrollers in the ATtiny series. They can be configured to serve various functions in your projects.

**8. Timers and PWM:** The MCU typically includes timers and pulse-width modulation (PWM) capabilities, which are valuable for tasks such as generating PWM signals, measuring time intervals, and controlling motor speeds.

**9. Analog-to-Digital Converter (ADC):** An ADC allows the microcontroller to convert analog signals (e.g., sensor readings) into digital values for processing.

**10. Voltage Supply:** The ATtiny85-20PU usually operates at a voltage supply range of 2.7V to 5.5V, which provides flexibility in terms of power supply options.

**11. Low Power:** This microcontroller is designed to be energy-efficient and can operate on low power, making it suitable for battery-powered and energy-conscious applications.

**12. Programming:** To program the ATtiny85-20PU, you can use an in-circuit programmer (ICSP) and development software compatible with Atmel/Microchip microcontrollers.

**13. DIY Projects:** The ATtiny85-20PU is commonly used in do-it-yourself (DIY) electronics projects, including home automation, sensor-based applications, LED displays, and more.

**14. Compact DIP-8 Package:** The “DIP-8” designation refers to the dual in-line package with eight pins, which is a common package for through-hole components. It allows for easy integration into various circuits and prototyping on breadboards.

In summary, the ATtiny85-20PU is a versatile and compact 8-bit microcontroller with features suitable for a wide range of embedded systems and DIY projects. Its low power consumption and small form factor make it a popular choice for applications where space and energy efficiency are crucial.
