Hi,

Is PN5321A3HN/C106,55 good to go for designing in custom board because previously in the website a few months back  I could see PN5321A3HN/C106,55 is NRND?

Also What is the difference between part numbers PN5321A3HN/C106,55 and PN5321A3HN/C106;55 because when I was searching for the stock in octopart I could see the price difference between these two part numberswhere PN5321A3HN/C106,55  price is $9.357 and PN5321A3HN/C106;55 price is $8.795?

Also  Does PN5321A3HN/C106,55 comes preprogrammed I mean driver code(firmware) loaded into PN5321A3HN/C106,55 so that we can use UART/SPI/I2C protocols to communicate with our custom board MCU or do we need to write entire registers or driver development from scratch?
