ATtiny85 Pinout: Main functions, application areas and alternative models

The ATtiny85 is a popular 8-bit AVR microcontroller manufactured by Microchip Technology (formerly Atmel). Below is information about the pinout, main functions, application areas, and some alternative models you can consider:

ATtiny85 Pinout:

The ATtiny85 typically comes in a 8-pin DIP (Dual In-line Package) form factor. Its pinout consists of the following pins:

1. Reset (PB5) - Reset pin.
2. Digital I/O Pin 0 (PB0) - General-purpose digital I/O pin.
3. Digital I/O Pin 1 (PB1) - General-purpose digital I/O pin.
4. Digital I/O Pin 2 (PB2) - General-purpose digital I/O pin.
5. Digital I/O Pin 3 (PB3) - General-purpose digital I/O pin.
6. Digital I/O Pin 4 (PB4) - General-purpose digital I/O pin.
7. Ground (GND) - Ground pin.
8. VCC (VCC) - Supply voltage pin.

Main Functions:

1. Low Power Consumption: The ATtiny85 is known for its low power consumption, making it suitable for battery-powered applications.

2. 8KB Flash Memory: Sufficient memory for small embedded projects and IoT applications.

3. 6 I/O Pins: Provides enough flexibility for various projects.

4. PWM (Pulse Width Modulation): Allows for hardware PWM output on certain pins.

5. ADC (Analog-to-Digital Converter): Capable of analog input readings for sensor interfacing.
