1.1.1

Pin Descriptions

VCC

Supply voltage.

1.1.2

GND

Ground.

1.1.3

AVCC

Analog supply voltage. This is the supply voltage pin for the Analog-to-digital Converter (ADC),

the analog comparator, the Brown-Out Detector (BOD), the internal voltage reference and Port

A. It should be externally connected to VCC, even if some peripherals such as the ADC are not

used. If the ADC is used AVCC should be connected to VCC through a low-pass filter.

1.1.4

AGND

Analog ground.

1.1.5

Port A (PA7:PA0)

An 8-bit, bi-directional I/O port with internal pull-up resistors, individually selectable for each bit.

Output buffers have symmetrical drive characteristics with both high sink and source capability.

As inputs, port pins that are externally pulled low will source current if pull-up resistors have

been activated. Port pins are tri-stated when a reset condition becomes active, even if the clock

is not running.

Port A also serves the functions of various special features of the device, as listed on

page 63.

1.1.6

Port B (PB7:PB0)

An 8-bit, bi-directional I/O port with internal pull-up resistors, individually selectable for each bit.

Output buffers have symmetrical drive characteristics with both high sink and source capability.

As inputs, port pins that are externally pulled low will source current if pull-up resistors have

been activated. Port pins are tri-stated when a reset condition becomes active, even if the clock

is not running.

Port B also serves the functions of various special features of the device, as listed on

page 66.

1.1.7

RESET

Reset input. A low level on this pin for longer than the minimum pulse length will generate a

reset, even if the clock is not running and provided the reset pin has not been disabled. The min-

imum pulse length is given in

Table 19-4 on page 190.

Shorter pulses are not guaranteed to

generate a reset.

The reset pin can also be used as a (weak) I/O pin.

ATtiny261/461/861

2. Overview

ATtiny261/461/861 are low-power CMOS 8-bit microcontrollers based on the AVR enhanced

RISC architecture. By executing powerful instructions in a single clock cycle, the

ATtiny261/461/861 achieves throughputs approaching 1 MIPS per MHz allowing the system

designer to optimize power consumption versus processing speed.

The AVR core combines a rich instruction set with 32 general purpose working registers. All 32

registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent

registers to be accessed in one single instruction executed in one clock cycle. The resulting

architecture is more code efficient while achieving throughputs up to ten times faster than con-

ventional CISC microcontrollers.

ATtiny261/461/861

The ATtiny261/461/861 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-chan-

nel, 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. 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 ATtiny261/461/861 AVR is supported by a full suite of program and system development

tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, and Evaluation

kits.
