The ATTINY13A-PU is a picoPower 8-bit AVR RISC-based Microcontroller features 64-byte EEPROM, 32-byte register file and 4-channel 10-bit A/D converter. The device achieves up to 20 MIPS throughput at 20MHz at 1.8 to 5.5V operation. By executing powerful instructions in a single clock cycle, the microcontroller achieves throughputs approaching 1 MIPS per MHz allowing you to optimize power consumption versus processing speed.
