SL2S2602 writing time

JpTBM — Tue, 08 Jun 2021 11:54:17 GMT

Hi,

For one RFID application, We are using tags with SL2S2602

Referred the datasheet, in which data transmission speed is specified as up to 53 kbit/s.

I actually want to write 316 Bytes block wise in tag, It is taking approx 1.5 seconds.

Requirement is to complete writing of 316 bytes in 0.5 seconds. Is it possible?

Can someone help me in understanding/calculating the timing required to write 316 bytes at one go in Tag using the commands mentioned in datasheet

thanks,

Jagdish

Hi @JpTBM ,

The 53 kbit/s is for the direction from tag to reader, please kindly refer to 9.5.3.11 FAST INVENTORY READ of https://www.nxp.com.cn/docs/en/data-sheet/SL2S2602.pdf for more details.

Have a great day,
Kan

Hi Kan,

Thanks for the details,

But still was unable to get the req'd data.

The document just specifies

The data rate from the interrogator to the ICODE SLIX2 IC and the time between the
rising edge of the EOF from the interrogator to the ICODE SLIX2 IC remain unchanged
(stay the same as defined in ISO/IEC 15693-3).

It just points to the standard (general statement), can you please help me reach the exact value as its not feasible for me to buy a standard to get the data.

thanks and regards,

Jagdish

Hi @JpTBM ,

I think we have already indicated it in the data sheet, and you may calculate it by yourself referring to the following:

Hope that helps,

Have a great day,
