1.1 Pin Descriptions
1.1.1 VCC
Digital supply voltage.
1.1.2 GND
Ground.
1.1.3 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 54.
1.1.4 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 18-1 on page
115. Shorter pulses are not guaranteed to generate a reset.
The reset pin can also be used as a (weak) I/O pin.

2. Overview
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 con-
sumption versus processing speed.

ATtiny13
The AVR core combines a rich instruction set with 32 general purpose working registers. All 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 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 reg-
isters, 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 soft-
ware 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 Inter-
rupt 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, and Evaluation kits.

3. General Information
3.1 Resources
A comprehensive set of drivers, application notes, data sheets and descriptions on development
tools are available for download at http://www.atmel.com/avr.
3.2 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 documen-
tation for more details.
3.3 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.

Notes: 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.ome 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.

8. Errata
The revision letter in this section refers to the revision of the ATtiny13 device.
8.1 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.
8.2 ATtiny13 Rev. C
Revision C has not been sampled.
8.3 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
8.3.1 Wrong values read after Erase Only operation
At supply voltages below 2.7 V, an EEPROM location that is erased by the Erase Only oper-
ation may read as programmed (0x00).
Problem Fix/Workaround
If it is necessary to read an EEPROM location after Erase Only, use an Atomic Write opera-
tion 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 loca-
tion is not read before it is programmed.
8.3.2 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.
8.3.3 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.
18
2535JS–AVR–08/10
ATtiny13
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.
8.3.4 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.
8.3.5 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.
8.3.6 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.
8.4 ATtiny13 Rev. A
Revision A has not been sampled.
