Summary

•

Rev. 2543IS–AVR–04/06

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

All the 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 conventional CISC microcontrollers.

The ATtiny2313 provides the following features: 2K bytes of In-System Programmable

Flash, 128 bytes EEPROM, 128 bytes SRAM, 18 general purpose I/O lines, 32 general

purpose working registers, a single-wire Interface for On-chip Debugging, two flexible

Timer/Counters with compare modes, internal and external interrupts, a serial program-

mable USART, Universal Serial Interface with Start Condition Detector, a programmable

Watchdog Timer with internal Oscillator, and three software selectable power saving

modes. The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, and

interrupt system to continue functioning. The Power-down mode saves the register con-

tents but freezes the Oscillator, disabling all other chip functions until the next interrupt

or hardware reset. In Standby mode, the crystal/resonator Oscillator is running while the

rest of the device is sleeping. This allows 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 reprogrammed In-System

through an SPI serial interface, or by a conventional non-volatile memory programmer.

By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a mono-

lithic chip, the Atmel ATtiny2313 is a powerful microcontroller that provides a highly

flexible and cost effective solution to many embedded control applications.

The ATtiny2313 AVR is supported with a full suite of program and system development

tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Cir-

cuit Emulators, and Evaluation kits.

Pin Descriptions

VCC

GND

Port A (PA2..PA0)

Digital supply voltage.

Ground.

Port A is a 3-bit bi-directional I/O port with internal pull-up resistors (selected for each

bit). The Port A output buffers have symmetrical drive characteristics with both high sink

and source capability. As inputs, Port A pins that are externally pulled low will source

current if the pull-up resistors are activated. The Port A 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 ATtiny2313 as listed

on page 53.

Port B (PB7..PB0)

Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each

bit). The Port B output buffers have symmetrical drive characteristics with both high sink

and source capability. As inputs, Port B pins that are externally pulled low will source

current if the pull-up resistors are activated. The Port B 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 ATtiny2313 as listed

on page 53.

Port D (PD6..PD0)

Port D is a 7-bit bi-directional I/O port with internal pull-up resistors (selected for each

bit). The Port D output buffers have symmetrical drive characteristics with both high sink

and source capability. As inputs, Port D pins that are externally pulled low will source

current if the pull-up resistors are activated. The Port D pins are tri-stated when a reset

condition becomes active, even if the clock is not running.

Port D also serves the functions of various special features of the ATtiny2313 as listed

on page 56.

RESET

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

ate a reset, even if the clock is not running. The minimum pulse length is given in Table

15 on page 34. Shorter pulses are not guaranteed to generate a reset. The Reset Input

is an alternate function for PA2 and dW.

Input to the inverting Oscillator amplifier and input to the internal clock operating circuit.

XTAL1 is an alternate function for PA0.

Output from the inverting Oscillator amplifier. XTAL2 is an alternate function for PA1.

A comprehensive set of development tools, application notes and datasheets are avail-

able for downloadon http://www.atmel.com/avr.
