Microchip ATMEGA328PB-MU, 8bit AVR Microcontroller, ATmega, 20MHz, 32 kB Flash, 32-Pin VQFN

The Microchip Technology ATMEGA family type, VQFN package, surface mount, 32-pin AVR RISC-based processor with a Pico power technology 8-bit microcontroller. It has a maximum voltage rating of 5.5V. This microcontroller operates at a maximum speed of 20MHz and features 32kb ISP flash program memory, 2kb of internal SRAM and 1kb of EEPROM. It has 27 programmable general-purpose I/O lines. It has an 8-channel 10-bit ADC in TQFP and QFN/MLF package, programmable watchdog timer with an internal oscillator and five software selectable power saving modes. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1MIPS per MHz, balancing power consumption and processing speed.
