ATTINY85-20MU Typical application Circuitry

ATTINY85-20MU

The ATTINY85-20MU is a compact, high-performance microcontroller from the popular AVR Tiny series by Microchip (formerly Atmel), designed for simplicity and efficiency in embedded applications. This microcontroller is well-suited for a variety of projects, including wearables, sensor control, and light automation, due to its small footprint, low power consumption, and versatile feature set.

1. Power Supply Connections (VCC and GND): To power the ATTINY85-20MU, the VCC pin should be connected to a positive power supply, typically 2.7V to 5.5V, and the GND pin to the ground. It's crucial to ensure a stable power supply to maintain the microcontroller's reliable operation, and decoupling capacitors are recommended close to these pins to filter out noise.

2. Reset Pin (PB5/RESET): The RESET pin allows for resetting the microcontroller to its initial state. This pin can be left unconnected for applications not requiring external reset functionality; however, it's generally advisable to connect a pull-up resistor to VCC to prevent unintentional resets due to noise.

3. Digital I/O Pins: The ATTINY85-20MU features six general-purpose I/O pins (PB0 to PB4 and PB5/RESET if not used as RESET), which can be configured as either input or output. These pins support various functionalities, including digital input/output, PWM output, and analog input, providing flexibility in interfacing with sensors, actuators, and other peripherals.

4. Analog Input (ADC): Among the I/O pins, three (PB2, PB3, and PB4) double as analog input channels, enabling the ATTINY85-20MU to read analog signals. This feature is particularly useful for sensor interfacing in applications requiring environmental monitoring or user input via potentiometers.

5. Clock Source: The ATTINY85-20MU can utilize its internal oscillator as a clock source, eliminating the need for an external crystal or resonator for most applications. However, for applications requiring precise timing, an external clock source can be connected to the PB3 pin.

6. Programming Interface: The microcontroller can be programmed via the SPI interface using the PB0 (MOSI), PB1 (MISO), PB2 (SCK), and PB5 (RESET) pins. This interface is used to upload firmware to the ATTINY85-20MU, typically through an AVR ISP programmer or a similar device.

7. Power Saving Modes: The ATTINY85-20MU supports multiple power-saving modes, allowing for reduced power consumption in battery-operated applications. Proper utilization of these modes can significantly extend battery life in portable devices.

Incorporating the ATTINY85-20MU into a project requires careful attention to each pin's connection and functionality. By leveraging its versatile I/O options and efficient power management features, the ATTINY85-20MU can serve as the intelligent core of a wide range of embedded systems, offering both performance and flexibility in a compact package.
