The ATtiny261A/ATtiny461A/ATtiny861A of microchip provides the
following features:
2/4/8K byte of In-System Programmable 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 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. Powerdown
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 development tools including: C Compilers, Macro
Assemblers, Program Debugger/Simulators, and Evaluation kits.
