Overview
2
The ATtiny13 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
ATtiny13 achieves throughputs approaching 1 MIPS per MHz allowing the system
designer to optimize power consumption versus processing speed.

2535GS–AVR–01/07
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 ATtiny13 provides the following features: 1K byte of In-System Programmable
Flash, 64 bytes EEPROM, 64 bytes SRAM, 6 general purpose I/O lines, 32 general purpose working registers, one 8-bit Timer/Counter with compare modes, Internal and
External Interrupts, a 4-channel, 10-bit ADC, 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/Counter, ADC, Analog Comparator, and
Interrupt system to continue functioning. The Power-down mode saves the register contents, disabling all chip functions until the next Interrupt or Hardware Reset. The ADC
Noise Reduction mode stops the CPU and all I/O modules except ADC, to minimize
switching noise during ADC conversions.
The device is manufactured using Atmel’s high density non-volatile memory technology.
The On-chip ISP Flash allows the Program memory to be re-programmed In-System
through an SPI serial interface, by a conventional non-volatile memory programmer or
by an On-chip boot code running on the AVR core.
The ATtiny13 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 B (PB5..PB0)
Port B is a 6-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 ATtiny13 as listed on
page 50.
RESET
4
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
12 on page 31. Shorter pulses are not guaranteed to generate a reset.

2535GS–AVR–01/07
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 operation 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.

Errata
The revision letter in this section refers to the revision of the ATtiny13 device.
ATtiny13 Rev. D
• EEPROM can not be written below 1.9 Volt
1. EEPROM can not be written below 1.9 Volt
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.
ATtiny13 Rev. B
•
•
•
•
•
•
Wrong values read after Erase Only operation
High Voltage Serial Programming Flash, EEPROM, Fuse and Lock Bits may fail
Device may lock for further programming
debugWIRE communication not blocked by lock-bits
Watchdog Timer Interrupt disabled
EEPROM can not be written below 1.9 Volt
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. High Voltage Serial Programming Flash, EEPROM, Fuse and Lock Bits may
fail
Writing to any of these locations and bits may in some occasions fail.
Problem Fix/Workaround
After a writing has been initiated, always observe the RDY/BSY signal. If the writing
should fail, rewrite until the RDY/BSY verifies a correct writing. This will be fixed in
revision D.
3. Device may lock for further programming
Special combinations of fuse bits will lock the device for further programming effectively turning it into an OTP device. The following combinations of settings/fuse bits
will cause this effect:
–
128 kHz internal oscillator (CKSEL[1..0] = 11), shortest start-up time
(SUT[1..0] = 00), Debugwire enabled (DWEN = 0) or Reset disabled
RSTDISBL = 0.
–
9.6 MHz internal oscillator (CKSEL[1..0] = 10), shortest start-up time
(SUT[1..0] = 00), Debugwire enabled (DWEN = 0) or Reset disabled
RSTDISBL = 0.
–
4.8 MHz internal oscillator (CKSEL[1..0] = 01), shortest start-up time
(SUT[1..0] = 00), Debugwire enabled (DWEN = 0) or Reset disabled
RSTDISBL = 0.
Problem fix/ Workaround
Avoid the above fuse combinations. Selecting longer start-up time will eliminate the
problem.

4. debugWIRE communication not blocked by lock-bits
When debugWIRE on-chip debug is enabled (DWEN = 0), the contents of program
memory and EEPROM data memory can be read even if the lock-bits are set to
block further reading of the device.
Problem fix/ Workaround
Do not ship products with on-chip debug of the tiny13 enabled.
5. 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 time-out 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.
6. EEPROM can not be written below 1.9 Volt
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.
