8235B–AVR–04/11
The resulting architecture is compact and code efficient while achieving throughputs up to ten
times faster than conventional CISC microcontrollers.
ATtiny20 provides the following features:
The device includes the following modes for saving power:
The device is manufactured using Atmel’s high density non-volatile memory technology. The on-
chip, in-system programmable Flash allows program memory to be re-programmed in-system by
a conventional, non-volatile memory programmer.
The ATtiny20 AVR is supported by a suite of program and system development tools, including
macro assemblers and evaluation kits.
• 2K bytes of in-system programmable Flash
• 128 bytes of SRAM
• Twelve general purpose I/O lines
• 16 general purpose working registers
• An 8-bit Timer/Counter with two PWM channels
• A 16-bit Timer/Counter with two PWM channels
• Internal and external interrupts
• An eight-channel, 10-bit ADC
• A programmable Watchdog Timer with internal oscillator
• A slave two-wire interface
• A master/slave serial peripheral interface
• An internal calibrated oscillator
• Four software selectable power saving modes
• Idle mode: stops the CPU while allowing the timer/counter, ADC, analog comparator, SPI,
• ADC Noise Reduction mode: minimizes switching noise during ADC conversions by stopping
• Power-down mode: registers keep their contents and all chip functions are disabled until the
• Standby mode: the oscillator is running while the rest of the device is sleeping, allowing very
TWI, and interrupt system to continue functioning
the CPU and all I/O modules except the ADC
next interrupt or hardware reset
fast start-up combined with low power consumption.
