attiny85

The ATtiny85 is a popular, low-power 8-bit microcontroller from the Atmel AVR family (now Microchip).

Key features:

  • Memory: 8KB Flash, 512B EEPROM, 512B SRAM.
  • Pins: 8-pin package with up to 6 general-purpose I/O pins.
  • Peripherals: Includes timers, a 10-bit ADC, and interfaces like SPI and I2C (via USI - Universal Serial Interface).
  • Clock: Can run up to 20 MHz with an external crystal, or use an internal oscillator (typically 8 MHz).
  • Simplicity: Known for its ease of use, small size, and low cost, making it ideal for simple embedded projects, wearables, and learning purposes. It's often programmed using the Arduino IDE with appropriate core libraries installed.
