Port B (PB3..PB0)
This is a 4-bit, bi-directional I/O port with internal pull-up resistors, individually selectable for
each bit. The output buffers have symmetrical drive characteristics, with both high sink and
source capability. As inputs, the port pins that are externally pulled low will source current if pullup resistors are activated. Port pins are tri-stated when a reset condition becomes active, even if
the clock is not running.
The port also serves the functions of various special features of the ATtiny4/5/9/10, as listed on
page 36.
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 and provided the reset pin has not been disabled. The minimum pulse length is given in Table 16-4 on page 119. Shorter pulses are not guaranteed to
generate a reset.
The reset pin can also be used as a (weak) I/O pin.

2. Overview
ATtiny4/5/9/10 are low-power CMOS 8-bit microcontrollers based on the compact AVR
enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the
ATtiny4/5/9/10 achieve 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 16 general purpose working registers and
system registers. All 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 compact and code efficient while achieving throughputs up to ten
times faster than conventional CISC microcontrollers.

8127CS–AVR–10/09
The ATtiny4/5/9/10 provide the following features: 512/1024 byte of In-System Programmable
Flash, 32 bytes of SRAM, four general purpose I/O lines, 16 general purpose working registers,
a 16-bit timer/counter with two PWM channels, internal and external interrupts, a programmable
watchdog timer with internal oscillator, an internal calibrated oscillator, and four software selectable power saving modes. ATtiny5/10 are also equipped with a four-channel, 8-bit Analog to
Digital Converter (ADC).
Idle mode stops the CPU while allowing the SRAM, timer/counter, ADC (ATtiny5/10, only), analog comparator, and interrupt system to continue functioning. ADC Noise Reduction mode
minimizes switching noise during ADC conversions by stopping the CPU and all I/O modules
except the ADC. In Power-down mode registers keep their contents and all chip functions are
disabled until the next interrupt or hardware reset. In Standby mode, the oscillator is running
while the rest of the device is sleeping, allowing very fast start-up combined with low power
consumption.
The device is manufactured using Atmel’s high density non-volatile memory technology. The onchip, in-system programmable Flash allows program memory to be re-programmed in-system by
a conventional, non-volatile memory programmer.
The ATtiny4/5/9/10 AVR are supported by a suite of program and system development tools,
including macro assemblers and evaluation kits.

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 documentation 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.
3.4
Disclaimer
Typical values contained in this datasheet are based on simulations and characterization of
other AVR microcontrollers manufactured on the same process technology. Min and Max values
will be available after the device has been characterized.

ATtiny4/5/9/10
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.
4. The ADC is available in ATtiny5/10, only.

8. Errata
The revision letters in this section refer to the revision of the corresponding ATtiny4/5/9/10
device.
8.1
8.1.1
ATtiny4
Rev. D
• ESD HBM (ESD STM 5.1) level ±1000V
• Lock bits re-programming
1. ESD HBM (ESD STM 5.1) level ±1000V
The device meets ESD HBM (ESD STM 5.1) level ±1000V.
Problem Fix / Workaround
Always use proper ESD protection measures (Class 1C) when handling integrated circuits
before and during assembly.
2. Lock bits re-programming
Attempt to re-program Lock bits to present, or lower protection level (tampering attempt),
causes erroneously one, random line of Flash program memory to get erased. The Lock bits
will not get changed, as they should not.
Problem Fix / Workaround
Do not attempt to re-program Lock bits to present, or lower protection level.
8.1.2
Rev. A – C
Not sampled.
8.2
8.2.1
