The ATtiny45 is a powerful 8-bit AVR microcontroller designed for compact and low-power applications. With 4KB of Flash memory, 256B EEPROM, and 256B SRAM, it is ideal for embedded systems, automation, and sensor-based projects.
Equipped with 6 I/O pins, an internal oscillator, and a 4-channel 10-bit ADC, the ATtiny45 can handle PWM, signal processing, and analog measurements with ease. It operates at up to 20MHz, ensuring efficient performance in various DIY electronics, robotics, and IoT applications.
Q: Can the ATtiny45 be programmed using Arduino IDE?
A: Yes, it can be programmed via Arduino IDE using an Arduino as ISP (In-System Programmer) or an external AVR programmer.
Q: Does this microcontroller support I2C or SPI communication?
A: Yes, it features a Universal Serial Interface (USI) that can be used for SPI or I2C communication with proper software implementation.
Q: What is the difference between ATtiny45 and ATtiny85?
A: The ATtiny85 has 8KB of Flash memory, while the ATtiny45 has 4KB. Other features remain the same.
Q: Can it be used for battery-powered applications?
A: Yes, it operates on 2.7V to 5.5V, making it suitable for low-power and battery-operated projects.
Q: Is an external crystal required?
A: No, it has a built-in internal oscillator but supports external clock sources if needed.
