comparsion:
The difference between the 328 and 328P is "picopower", which might mean lower power consumption in powerdown modes, but the only visible difference is the ability to turn off brown-out detection in software.
The 328PB should have been a different part number :frowning: . It has extra I2C, SPI, and UART peripherals, two additional 16bit timers, the ability to use what were analog-only pins for digital IO, removes a set of power pins, has a unique serial number, clock failure detection, more explicit support for Touch IO, and isn't available in DIP. And the PB is cheaper.
