Question about PN5180 datasheet, RANDOM_UID_ENABLE

OilCastle — Wed, 24 Mar 2021 02:46:02 GMT

Hello, I have some questions about PN5180 datasheets.

In section 11.5.2 EEPROM (Table 51.), address [0x51] and [0x58] have same descriptions.

I'm little confused. Should I use both or what? or is it some typo?

And what's the difference data sheet suffix "_C3_C4" and "-C1-C2"

Is "PN5180A0XX-C1-C2.pdf" document just older version of "PN5180A0XX_C3_C4.pdf" ?

FYI, I attach some part of EEPROM address table from "PN5180A0XX-C1-C2.pdf".

As you can see, it's from first image.

Thanks, and have a good day.

Hello,

The 0x51 is the value to activate the RandomID and the 0x58 stores the UID03.

And the difference of the C1/C2 and C3 version is Firmware version. Please refer to the datasheet for the detail information.

Hope it help you. Have a nice day.
