Comparison Between ATtiny2313A and ATtiny4313
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 ATtiny2313A/4313 provides the following features: 2/4K bytes of In-System Programmable
Flash, 128/256 bytes EEPROM, 128/256 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 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 func-
tioning. 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 crys-
tal/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 monolithic chip, the Atmel
ATtiny2313A/4313 is a powerful microcontroller that provides a highly flexible and cost effective
solution to many embedded control applications.
The ATtiny2313A/4313 AVR is supported with a full suite of program and system development
tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Circuit Emu-
lators, and Evaluation kits.
The ATtiny2313A and ATtiny4313 differ only in memory sizes.
