ATMEGA168PB-MU Datasheet PDF - Microchip

●The ATMEGA168PB-MU is a high-performance picoPower 8-bit AVR RISC-based Microcontroller combines 16kB ISP flash memory with read-while-write capabilities, 512byte EEPROM, 1kB SRAM, 27 general purpose I/O lines, 32 general-purpose working registers, three flexible timers/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 1MIPS per MHz, balancing power consumption and processing speed. The device is manufactured using the Atmel high density non-volatile memory technology.
