Part Number: TRF7961 Other Parts Discussed in Thread: MSP-EXP430G2ET Hi Team TRF, My customer has the following questions..
"We are using a TI part TRF7961 on our one of our projects. We are planning to send the unit for external testing and one of…
Hello,
no, the TRF7961 is not able to communicate directly with another TRF7961.
The required modes are only supported by the TRF7970A.
For more information please see the overview of the supported protocols in the TRF79xx FAQ section 1.2:

Part Number: TRF7961 Other Parts Discussed in Thread: TRF7960 Hi,
I'm trying to get the TRF7961 to work, but it doesn't seem to be writing registers properly - when I do a read after a write, the changes don't show up (returns the default value, not…
Part Number: TRF7961 Other Parts Discussed in Thread: TRF7970A Hi Team,
Our customer used the TRF7961 for their product development. Using the application schematic in the datasheet, they were able to get about 12cm reading and writing distance. Is…
Hello Mike,
In theory, both.
If the TRF7961 receives a command it can process, it would process it and attempt to reply if the command would cause such a behavior. Such a reply would impact other devices on the SPI bus. Furthermore, if it processes…
usually it ends up working within a certain range. Slightly more load cap is generally OK, but you should try to stay with what the crystal manufacturer indicates their devices need for startup. the TRF79xxA requirements are based on regulatory requirements…
Part Number: TRF7961 Tool/software: Starterware in my application, TRF7961 VIN is powered by battery(2.75V~3.4V),VDD_I/O is connected to 2V8(MCU is also powered by 2V8),but VDD_X is not connected to VDD_I/O, is there any problem ?
Hello Helfried,
Do these IC's have the same pinout and footprint as TRF7961. The reason i'm asking this is that i have a product with TRF7961 and i want to simply replace that IC with one that supports ISO14443-a without changing anything in my PCB…
Hello Ralph,
After Setting the Bit B2 (which is mentioned as reserved in TRF7961 datasheet) in the chip control register(0x00) the commands have started working perfectly for me. Do have any idea about the significance of that bit ?
