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
