ATTINY45-20PU Datasheet PDF - ATMEL

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
