SE050 + NTAG5 Boost

julian_sauer — Tue, 21 Apr 2020 22:25:10 GMT

Hello NXP-Community,

I am using at the moment the development Board OM2NTA5332 (NTAG5 Boost) + the OM-SE050ARD (SE050) in which the NTAG5 Boost is the I2C Master and the SE050 is the I2C Slave (default slave address 0x48).

I want to send the APDU Commands via NTAG5 Boost (NFC) to the SE050 and read the Response out of the SRAM.

Any specific drivers needed for the SE050 to communicate between these boards correctly - for the SE050 I am using the "a7x_vcom-T1oI2C-frdmk64f-SE050x.bin" at the moment which is probably the wrong one.

Which driver would be compatible to the NTAG5 Boost?

best regards

Julian

Hi Julian,

I am sorry, but why is NTAG5 used? SE050 supports NFC interface communication directly, please kindly refer to https://www.nxp.com/docs/en/nxp/application-notes/AN12664.pdf and "5.4.1 ISO/IECC 144443-A via onboarded antenna" in https://www.nxp.com/docs/en/application-note/AN12395-OM-SE050ARD_hardware_overview.pdf for more details.

Hope that helps,

Have a great day,
Kan

Hi Kan,

we want to use the NTAG5 Boost because of the Energy Harvesting functionality. Using the ISO 14443 from the SE050 C would mean the power has to come from a external source.

Hi Julian,

Thanks for the clarification! If so, there is no specific driver needed for either OM2NTA5332 (NTAG5 Boost) or OM-SE050ARD (SE050) , you may just connect them as below:

and send APDU commands in T=1 format over I2C as below(This is usually be implemented on the NFC reader side, for example , a NFC phone):

Please kindly refer to the following links for more details.
