Regarding Higher read range in SLRC610 (CLEV6630B)

[manan1249]

hello,

Greetings of the day!

I am using CLEV6630B V2.0 board with nxp reader library (I changed the CLRC663 IC to SLRC610).

As per the ISO15693 protocol documentation, range of ISO15693 is 1 meter. But i am getting only 14 cm.

Also i changed the Gain register of SLRC610 chip, but there is no improvement in range.

So for higher range what changes i have to do?

And also i read in NXP Website about SLRC610 is that 

Not recommended for new designs. For new designs, please use recommended product CLRC663 plus.

Why it is not recommended for new designs?

In our application we require two protocol for RFID: ISO15693, ISO18000-3

Is there any other alternative for SLRC610 for higher read range?

Your quick reply would be highly appreciated.

Thank You!

Hi,

Hope you are doing well.

The CLRC663 plus family has a product longevity of 10 year from his launch (Jun 2017), so is going to be manufactured and supported all this time.

The CLRC663 does support the ISO-15693 and the ISO-18000-3 in a maximum range for the NFC Range limitation: up to 5-10 cm.

The SLRC610 supports the ISO-15693 and the ISO-18000-3 too and a larger range but you will need to design the antenna according to those distances, you can check the following webinars to help you in the process.

Let me check if I have more information about it and let you know in case I get any other information.

Best Regards,

Ricardo

hello,

Thank you for your quick reply.

I want to ask you that can we use SLRC610 chip for new design?

Thanks & regards

Hi Manan,

I asked about this information, and we recommend the SLRC61003 instead of the SLRC61002. Because the SLRC61003 offers the same or better functionality at the same price.

And just to clarify, the SLRC610 is a proximity reader, you could get some higher range with the antenna design process, but it cannot achieve 1m operation distance. The I-Code tags are the ones can achieve distances of 1m.

Best Regards,

Ricardo
