8K Bytes of In-System Self-Programmable Flash, 512 Bytes In-System Programmable EEPROM, 512 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 16 MIPS throughput at 16 MHz. 2.7 - 5.5 V operation.
ATtiny45/ATtiny45V 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 ATtiny45/ATtiny45V achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed。
