I want to upgrade my product which is based on Atmega328p-AU, having the problem of programming memory. I don't want to change the PCB of the product. Is PIN To PIN matching MCU against Atmega328P-AU available?

    Too little RAM, or too little Flash memory? – Gerben Apr 29 at 9:47

The only other AVR chip with more program memory in the 32/TQFP form factor is the ATMEGA4808 at 48 kB.

Unfortunately, the pinout is not the same compared to the ATMEGA328P-AU:
