architecture is more code efficient while achieving throughputs up to ten times faster than con-
ventional CISC microcontrollers.
The ATtiny24/44/84 provides the following features: 2/4/8K byte of In-System Programmable
Flash, 128/256/512 bytes EEPROM, 128/256/512 bytes SRAM, 12 general purpose I/O lines, 32
general purpose working registers, a 8-bit Timer/Counter with two PWM channels, a 16-bit
timer/counter 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 three software select-
able 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. In Standby mode, the crys-
tal/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 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 ATtiny24/44/84 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.

Automotive Quality Grade
The ATtiny24/44/84 have been developed and manufactured according to the most stringent
requirements of the international standard ISO-TS-16949 grade 1. This data sheet contains limit
values extracted from the results of extensive characterization (Temperature and Voltage). The
quality and reliability of the ATtiny24/44/84 have been verified during regular product qualifica-
tion as per AEC-Q100.
As indicated in the ordering information paragraph, the product is available in only one tempera-
ture grade,
