ATtiny43U is an ultra low-voltage picoPower microcontroller in the Atmel AVR family. It is available in either the 20-pin SOIC or the 20-pin QFN package with a 4 or 8 MHz selectable clock speed. Running higher clock speeds require higher minimum operating voltages, with 1.8 volts for 4 MHz and 2.7 volts for 8 MHz.
The ATtiny43U has the following features:
- 8 touch channels
- 1 SPI
- 1 I2C
- 10-bit with 4 channels
- 1 analog comparator
- temperature sensor
- 2 timers
- 4 PWM
- internal RC oscillator
- watchdog
