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.

AVR CPU Core
Introduction
Architectural
Overview
This section discusses the AVR core architecture in general. The main function of the CPU core
is to ensure correct program execution. The CPU must therefore be able to access memories,
perform calculations, control peripherals, and handle interrupts.

In order to maximize performance and parallelism, the AVR uses a Harvard architecture – with
separate memories and buses for program and data. Instructions in the program memory are
executed with a single level pipelining. While one instruction is being executed, the next instruc-
tion is pre-fetched from the program memory. This concept enables instructions to be executed
in every clock cycle. The program memory is In-System Reprogrammable Flash memory.
The fast-access Register File contains 32 x 8-bit general purpose working registers with a single
clock cycle access time. This allows single-cycle Arithmetic Logic Unit (ALU) operation. In a typ-
ical ALU operation, two operands are output from the Register File, the operation is executed,
and the result is stored back in the Register File – in one clock cycle.
