Description

The ATTINY11L-2SU is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. It executes powerful instructions in a single clock cycle, achieving throughputs approaching 1 MIPS per MHz. The AVR core combines a rich instruction set with 32 general-purpose working registers, allowing for efficient code execution and faster processing speeds compared to conventional CISC microcontrollers. This microcontroller is ideal for applications where power consumption needs to be optimized while maintaining processing speed.
