ATtiny4/5/9/10
four software selectable power saving modes. ATtiny5/10 are also equipped with a four-channel, 8-bit Analog to Digital
Converter (ADC).
Idle mode stops the CPU while allowing the SRAM, timer/counter, ADC (ATtiny5/10, only), analog comparator, and inter-
rupt system to continue functioning. ADC Noise Reduction mode minimizes switching noise during ADC conversions by
stopping the CPU and all I/O modules except the ADC. In Power-down mode registers keep their contents and all chip
functions are disabled until the next interrupt or hardware reset. In Standby mode, the oscillator is running while the rest of
the device is sleeping, allowing very fast start-up combined with low power consumption.
The device is manufactured using 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 ATtiny4/5/9/10 AVR are supported by a suite of program and system development tools, including macro assemblers
and evaluation kits.
