Hi Claudio,
Yes, the TRF7970A is pin-compatible. Additionally if you want to only use Reader/Writer mode, you can use the TRF7964A which has only Reader/Writer enabled and comes at lower price point. That chip is also pin-compatible and will work with…
Hello Howard,
For the TRF7963A that is your only option. Expect approval on Monday, though it could happen sooner.
If you consider using the TRF7970A or TRF7964A you can refer to this example as these devices have Special Direct Mode functionality…
Hello Nomoto-san,
"Also, please confirm whether the dummy write must be inserted."
In the TRF7970A (and TRF7964A) this is not required. This was needed for the TRF7960A family of devices.
Please follow Josh's suggestions on the startup sequence…
Hello Josh,
your plan is very helpful and i begin to understand, what the components are doing.
But i am software expert (cryptology specialist) and my experience with those type of electrical parts is 20 years old (i had contact at study times…
Hello Mohammed,
The TRF7970A or TRF7964A would be the devices you want to look at.
For initial evaluation, you can check out our Reader/Writer app note and firmware example: www.ti.com/.../sloa227.pdf
If you want to test out specific APDU's for…
Hello NA,
I am not familiar with the S6700 at all - the device is well before my time and I've never used it. Perhaps Josh may have some ideas specifically for it, however I can at least help from an ISO15693 standard perspective.
For Write Single…
Hello Brian,
There aren't a lot of options for those devices.
For the RF430FRL152H, we have two variants, the 153H has no eUSCI (so no I2C/SPI) and the 154H has no SD14. No other variations for this.
The TRF79xx family has a few variations based…
Hello Janet,
Using a TI example (Josh provided two which work for the TRF7963A) will give them firmware which can read a sector. Then they just need to edit the application to do the 'rolling' reads as they need for the application.
Also if they are…
for the LF then go with the TRF4140 or the TPIC (if you really think that you want to provide dual frequency solution)
for the 13.56MHz side, you have options, based on the protocols you want to support and the cost targets you have.
the TRF79xxA…
