Overview
2
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.

2543MS–AVR–10/16
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.

Pin Descriptions
VCC
Digital supply voltage.
GND
Ground.
Port A (PA2..PA0)
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 function for PA2 and dW.
XTAL1
Input to the inverting Oscillator amplifier and input to the internal clock operating circuit. XTAL1
is an alternate function for PA0.
XTAL2
Output from the inverting Oscillator amplifier. XTAL2 is an alternate function for PA1.

Code Examples
This documentation contains simple code examples that briefly show how to use various parts of
the device. These code examples assume that the part specific header file is included before
compilation. Be aware that not all C compiler vendors include bit definitions in the header files
and interrupt handling in C is compiler dependent. Please confirm with the C compiler documentation for more details.
Data Retention
Reliability Qualification results show that the projected data retention failure rate is much less
than 1 PPM over 20 years at 85°C or 100 years at 25°C.

Note:
1. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses
should never be written.
2. I/O Registers within the address range 0x00 - 0x1F are directly bit-accessible using the SBI and CBI instructions. In these
registers, the value of single bits can be checked by using the SBIS and SBIC instructions.
3. Some of the status flags are cleared by writing a logical one to them. Note that, unlike most other AVRs, the CBI and SBI
instructions will only operate on the specified bit, and can therefore be used on registers containing such status flags. The
CBI and SBI instructions work with registers 0x00 to 0x1F only.
4. When using the I/O specific commands IN and OUT, the I/O addresses 0x00 - 0x3F must be used. When addressing I/O
Registers as data space using LD and ST instructions, 0x20 must be added to these addresses.

Wrong values read after Erase Only operation
Parallel Programming does not work
Watchdog Timer Interrupt disabled
EEPROM can not be written below 1.9 volts
1. Wrong values read after Erase Only operation
At supply voltages below 2.7 V, an EEPROM location that is erased by the Erase Only operation may read as programmed (0x00).
Problem Fix/Workaround
If it is necessary to read an EEPROM location after Erase Only, use an Atomic Write operation with 0xFF as data in order to erase a location. In any case, the Write Only operation can
be used as intended. Thus no special considerations are needed as long as the erased location is not read before it is programmed.
2. Parallel Programming does not work
Parallel Programming is not functioning correctly. Because of this, reprogramming of the
device is impossible if one of the following modes are selected:
–
In-System Programming disabled (SPIEN unprogrammed)
–
Reset Disabled (RSTDISBL programmed)
Problem Fix/Workaround
Serial Programming is still working correctly. By avoiding the two modes above, the device
can be reprogrammed serially.
3. Watchdog Timer Interrupt disabled
If the watchdog timer interrupt flag is not cleared before a new timeout occurs, the watchdog
will be disabled, and the interrupt flag will automatically be cleared. This is only applicable in
interrupt only mode. If the Watchdog is configured to reset the device in the watchdog timeout following an interrupt, the device works correctly.
Problem fix / Workaround
Make sure there is enough time to always service the first timeout event before a new
watchdog timeout occurs. This is done by selecting a long enough time-out period.
4. EEPROM can not be written below 1.9 volts
Writing the EEPROM at VCC below 1.9 volts might fail.
Problem fix / Workaround
Do not write the EEPROM when VCC is below 1.9 volts.
