The ATmega168 is a high-performance, low-power 8-bit AVR microcontroller from Atmel, based on the RISC architecture. It features 16KB of In-System Programmable (ISP) Flash, 1KB of SRAM, 512 bytes of EEPROM, an 8-channel 10-bit ADC (available in TQFP and QFN/MLF packages), and debugWIRE for on-chip debugging.
Operating at 2.7–5.5V, the ATmega168 delivers up to 20 MIPS at 20 MHz. With powerful instructions executed in a single clock cycle, it achieves 1 MIPS per MHz, offering an excellent balance of processing speed and power efficiency for a wide range of embedded applications.
