RFID Tag wrong datasheet

pragashsangaran — Sat, 09 May 2026 09:42:02 GMT

We want to use SL3S1013FTB0,115 tag in our product. However, when we click to open the data sheet, it opens SL3S1003_1013's datasheet. It's so confusing, and I wasted a lot of time with this confusion.

My question is whether SL3S1013FTB0 and SL3S1003_1013 are the same? If yes, why have two different part numbers for a single part? It's really frustrating and a waste of time for us. i

The IC type is different. In the Chapter 4 Ordering Information, you can see the SL3S1013 is G2iM+. The SL3S1003 is G2iM.

You are the different part and ask me to refer to 4. So what is the difference between SL3S1013FTB0,115 and SL3S1003_1013? Only packaging?

SL3S1003_1013 is the name of the datasheet. It means it is the datasheet of SL3S1003 and SL3S1013. The SL3S1013 is G2iM+. The SL3S1003 is G2iM. The UCODE G2iM+ offers on top of the UCODE G2iM features an integrated tag tamper alarm, digital switch, external supply mode, data transfer mode and real read range reduction. A special feature is the conditional, automatic real read range reduction, where the activation condition can be defined by the user, is newly introduced in the UCODE G2iM+. When connected to a power supply, the READ as well as the WRITE range can be boosted to a sensitivity of -27 dBm.

The UCODE G2iM+ also allows the segmentation of the 640 bit User Memory in up to three segments (open, protected, private) with different access levels (Access- and User Password). For applications which require a longer EPC number the UCODE G2iM+ offers the possibility of up to 448 bit.

My questions are as follows:

Your comment: A special feature is the conditional, automatic real read range reduction, where the activation condition can be defined by the user, is newly introduced in the UCODE G2iM+.

My question: How can we reduce the UCODE G2iM+ read range? I’m asking this because there are no serial communication lines available to connect to the MCU, so I don’t know how we can control the read range.

Your comment: When connected to a power supply, the READ as well as the WRITE range can be boosted to a sensitivity of -27 dBm.

My question: I have attached the pinouts and connections of UCODE G2iM+. How this read and write is done? Is it through the RFID connection?

The UCODE G2iM+ offers on top of the UCODE G2iM features an integrated tag tamper alarm, digital switch, external supply mode, data transfer mode and real read range reduction.

My question: can you please explain integrated tag tamper alarm, digital switch, external supply mode, data transfer mode, and real read range reduction modes? The reason is that I would like to see how I can utilize those features in my product.

My question: Please see the attached picture. The self-powered RFID transponder connection. Please let me know if this connection will result in 2V to 5V Vout from RFID energy harvesting.

im still waiting for an answer. NXP should know how to use their product, and that's what I want to know. i have two more questions.

1) In a self-power RFID transponder, what is the voltage range at the OUT?

2) In an external-power RFID transponder, what is the voltage range at the OUT?
