ATtiny261A/461A/861A
The ATtiny261A/461A/861A provides the following features: 2/4/8K byte of In-System Program-
mable Flash, 128/256/512 bytes EEPROM, 128/256/512 bytes SRAM, 16 general purpose I/O
lines, 32 general purpose working registers, an 8-bit Timer/Counter with compare modes, an 8-
bit high speed Timer/Counter, a Universal Serial Interface, Internal and External Interrupts, an
11-channel, 10-bit ADC, a programmable Watchdog Timer with internal oscillator, and four soft-
ware 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 contents, 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. In Standby mode, the crystal/resonator
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 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 ATtiny261A/461A/861A AVR is supported by a full suite of program and system develop-
ment tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, and
Evaluation kits.
