Preliminary

Description

The ATtiny22L is a low-power CMOS 8-bit microcontroller based on the AVR RISC

architecture. By executing powerful instructions in a single clock cycle, the ATtiny22L

achieves throughputs approaching 1 MIPS per MHz allowing the system designer to

optimize power consumption versus processing speed.

The AVR core combines a rich instruction set with 32 general purpose working regis-

ters. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU),
