2K Bytes of In-System Self-Programmable Flash, 128 Bytes In-System Programmable EEPROM, 128 Bytes Internal SRAM. Two 8-bit timer/counters with PWM and prescaler, 10-bit ADC, USI-Universal Serial Interface. debugWIRE for on-chip-debug. Up to 20 MIPS throughput at 20 MHz. 1.8 - 5.5 V operation.
The ATtiny25/45/85 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 ATtiny25/45/85
achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize
power consumption versus processing speed.
