I am using LPC8N04. And for testing I am using NXP Tag writer application. For a test I used same app on different phones. Firstly I used Sony Xperia and then I used Moto 5. Weird thing is, both phones show different memory size of the LPC8N04 NFC. Data sheet says it has 512 bytes but app running in SONY displays "524 bytes" and App running in Moto displays 54 bytes! So which is correct?
