The ATMEGA168A-MMH is a high-performance, low-power Microchip picoPower® 8-bit AVR® RISC-based microcontroller that combines 16KB ISP flash memory, 512-Byte EEPROM, 1KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible Timer/Counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, a 6-channel 10-bit A/D converter (8 channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes. The device operates between 1.8-5.5 volts.

By executing powerful instructions in a single clock cycle, the ATMEGA168A-MMH achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed. This microcontroller is designed for more complex applications where a small package leads to a more compact and space-saving design. It is particularly suitable for automotive, industrial, consumer, and Internet of Things (IoT) applications where robust operation and power efficiency are crucial.
