Rev. 2543L–AVR–08/10

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 con-

ventional 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 work-

ing registers, a single-wire Interface for On-chip Debugging, two flexible Timer/Counters with

compare modes, internal and external interrupts, a serial programmable 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 contents but freezes the Oscillator, disabling all other chip

functions until the next interrupt or hardware reset. In Standby mode, the crystal/resonator Oscil-

lator 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 monolithic 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-Circuit 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 generate 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 func-

tion 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.
