ATtiny13A
2. Overview
The ATtiny13A 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 ATtiny13A achieves
throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power con-
sumption versus processing speed.
