Product Overview

The Atmel ATTINY45-20PU is a high performance and low power AVR 8-bit microcontroller with 4K bytes of in-system programmable flash, alongside 256 bytes of EEPROM and 256 bytes of SRAM. The device is manufactured using Atmel’s high density non-volatile memory technology. The on-chip ISP flash allows the program memory to be re-programmed in-system through an SPI serial interface, by a conventional non-volatile memory programmer or by an on-chip boot code running on the AVR core.
  • Universal serial interface with start condition detector
  • Comes with debugWIRE on-chip debug system
  • In-system programmable via SPI port
  • Low power idle, ADC noise reduction and power-down modes
  • Six programmable input and output lines
  • External and internal interrupt sources
  • Programmable brown-out detection circuit
  • Internal calibrated oscillator
  • On-chip analogue comparator
  • 8-bit high speed timer/counter with separate prescaler and two PWM channels
