ATtiny828 is a microcontroller in the Atmel AVR family. It is available in either the 32-pin TQFP or the 32-pin QFN package with a 2, 4, 10, or 20 MHz selectable clock speed. Runnning at 2 MHz requires an operating voltage range of 1.7 to 1.8 volts, while running higher clock speeds require higher minimum operating voltages, with 1.8 volts for 4 MHz, 2.7 volts for 10 MHz, and 4.5 volts for 20 MHz.

The ATtiny828 has the following features:

  • 10-bit ADC with 28 channels
  • 1 analog comparator
  • 2 timers
  • 4 PWM channels
  • 32 kHz RTC
  • internal RC oscillator
  • 1 UART
  • 1 I2C
  • 1 SPI
  • watchdog
