ATtiny25/45/85 [DATASHEET]
2586O–AVR–02/13
The ATtiny25/45/85 provides the following features: 2/4/8K bytes of In-System Programmable Flash, 128/256/512
bytes EEPROM, 128/256/256 bytes SRAM, 6 general purpose I/O lines, 32 general purpose working registers, one
8-bit Timer/Counter with compare modes, one 8-bit high speed Timer/Counter, Universal Serial Interface, Internal
and External Interrupts, a 4-channel, 10-bit ADC, a programmable Watchdog Timer with internal Oscillator, and
three software selectable power saving modes. Idle mode stops the CPU while allowing the SRAM, Timer/Counter,
ADC, Analog Comparator, and Interrupt system to continue functioning. Power-down mode saves the register con-
tents, disabling all chip functions until the next Interrupt or Hardware Reset. ADC Noise Reduction mode stops the
CPU and all I/O modules except ADC, to minimize switching noise during ADC conversions.
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.
The ATtiny25/45/85 AVR is supported with a full suite of program and system development tools including: C Com-
pilers, Macro Assemblers, Program Debugger/Simulators and Evaluation kits.
