ATMEGA168PB-AU Datasheet PDF - Microchip

●The ATMEGA168PB-AU is a high-performance picoPower® 8-bit AVR RISC-based Microcontroller combines 16kb ISP flash memory with read-while-write capabilities, 512B EEPROM, 27 general purpose I/O lines, 32 general-purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, USART with wake-up on start of transmission, a byte-oriented 2-wire serial interface, SPI serial port, 8-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, a 9 byte unique serial number and five software selectable power-saving modes. The device operates between 1.8 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
