Atmel MEGA328PB-U (ATMega328PB-U) SMD IC

ATmega328PB is not a drop-in replacement for ATmega328 variants, but a new device. However, the functions are backwards compatible with the existing ATmega328 functions. Existing code for these devices will work in the new devices without changing the existing configuration or enabling new functions. The code that is available for your existing ATmega328 variants will continue to work on the new ATmega328PB device.
The ATmega328PB is the first 8-bit Atmel AVR device to feature the successful Atmel QTouch Peripheral Touch Controller (PTC). The ATmega328PB is the first 8-bit Atmel AVR device to feature the successful Atmel QTouch Peripheral Touch Controller (PTC). The Peripheral Touch Controller (PTC) acquires signals in order to detect a touch on capacitive sensors. The external capacitive touch sensor is typically formed on a PCB, and the sensor electrodes are connected to the analog front end of the PTC through the I/O pins in the device. The PTC supports both self and mutual capacitance sensors.
