Port B (PB3...PB0)  
Port B is a 4-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 except PB3 which has the RESET capability. To use pin PB3 as an I/O pin, instead of  
RESET pin, program (‘0’) RSTDISBL fuse. 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 ATtiny24A/44A as listed in  
Section 10.2 “Alternate Port Functions” on page 57.  
1.1.4  
1.1.5  
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 min-  
imum pulse length is given in Table 20-4 on page 176. Shorter pulses are not guaranteed to  
generate a reset.  
The reset pin can also be used as a (weak) I/O pin.  
Port A (PA7...PA0)  
Port A is a 8-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 has alternate functions as analog inputs for the ADC, analog comparator, timer/counter,  
SPI and pin change interrupt as described in “Alternate Port Functions” on page 57.

2. Overview  
ATtiny24A/44A are low-power CMOS 8-bit microcontrollers based on the AVR enhanced RISC  
architecture. By executing powerful instructions in a single clock cycle, the ATtiny24A/44A  
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 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.

ATtiny24A/44A  
8183BS–AVR–03/10  
ATtiny24A/44A  
The ATtiny24A/44A provides the following features: 2K/4K byte of In-System Programmable  
Flash, 128/256 bytes EEPROM, 128/256 bytes SRAM, 12 general purpose I/O lines, 32 general  
purpose working registers, an 8-bit Timer/Counter with two PWM channels, a 16-bit timer/coun-  
ter with two PWM channels, Internal and External Interrupts, a 8-channel 10-bit ADC,  
programmable gain stage (1x, 20x) for 12 differential ADC channel pairs, a programmable  
Watchdog Timer with internal oscillator, internal calibrated oscillator, and four software select-  
able power saving modes. Idle mode stops the CPU while allowing the SRAM, Timer/Counter,  
ADC, 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 mod-  
ules except the ADC. In Power-down mode registers keep their contents and all chip functions  
are disbaled until the next interrupt or hardware reset. In Standby mode, the crystal/resonator  
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 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 ATtiny24A/44A AVR is supported with a full suite of program and system development tools  
including: C Compilers, Macro Assemblers, Program Debugger/Simulators and Evaluation kits.

3.1  
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.  
For I/O Registers located in the extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI”  
instructions must be replaced with instructions that allow access to extended I/O. Typically, this  
means “LDS” and “STS” combined with “SBRS”, “SBRC”, “SBR”, and “CBR”. Note that not all  
AVR devices include an extended I/O map.  
3.3  
3.4  
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.  
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.

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.

9. Datasheet Revision History  
9.1  
Rev. 8183B – 03/10  
1. Updated template.  
2. Added UFBGA package (15CC1) in: “Features” on page 1, “Pin Configurations” on  
page 2, Section 6. “Ordering Information” on page 11, and Section 7.3 “15CC1” on  
page 15.  
3. Separated typical characteristic plots, added Section 21.2 “ATtiny24A” on page 183.  
4. Updated sections:  
Section 14.5.4 “USIBR – USI Buffer Register” on page 127, header updated  
Section 6. “Ordering Information” on page 11, added tape & reel and topside  
marking, updated notes  
5. Updated Figures:  
Figure 4-1 “Block Diagram of the AVR Architecture” on page 7  
Figure 8-1 “Reset Logic” on page 37  
Figure 14-1 “Universal Serial Interface, Block Diagram” on page 116, USIDB ->  
USIBR  
Figure 19-5 “High-voltage Serial Programming Waveforms” on page 169  
6. Updated Tables:  
Table 19-11, “Minimum Wait Delay Before Writing the Next Flash or EEPROM  
Location,” on page 164, updated value for tWD_ERASE  
9.2  
Rev. 8183A – 12/08  
1. Initial revision. Created from document 8006H.  
2. Updated "Ordering Information" on page 18 and page 18. Pb-plated packages are no  
longer offered and there are no separate ordering codes for commercial operation  
range, the only available option now is industrial. Also, updated some order codes to  
reflect changes in leadframe composition and added VQFN package option.  
3. Updated data sheet template.  
4. Removed all references to 8K device.  
5. Updated characteristic plots of section “Typical Characteristics”, starting on page 182.  
6. Added characteristic plots:  
“Internal Bandgap Voltage vs. Supply Voltage” on page 233  
“Internal Bandgap Voltage vs. Temperature” on page 233  
7. Updated sections:  
“Features” on page 1  
“Power Reduction Register” on page 34  
“Analog Comparator” on page 128  
“Features” on page 132  
“Operation” on page 133  
“Starting a Conversion” on page 134  
“ADC Voltage Reference” on page 139  
19  
8183BS–AVR–03/10  
“Speed Grades” on page 174  
8. Updated Figures:  
“Program Memory Map” on page 15  
“Data Memory Map” on page 16  
9. Update Tables:
