8-bit Microcontroller with 2/4/8K Bytes In-System Programmable Flash

Atmel Corporation 

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 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 ng 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.
