ATTINY2313 ATTINY2313V 8-bit Microcontroller with 2K Bytes
In-System Programmable Flash
Overview:
The ATtiny2313 is a low-power CMOS 8-bit microcontroller based on
the AVR enhanced RISC architecture.
By executing powerful instructions in a single clock cycle, the
ATtiny2313 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 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 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
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 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.
