NXP NFC speed of pass through mode

[Owenking]

I use NXP NFC chip: NTAG I2C 2K Plus.

I try to use pass through mode to transmit the message from NFC to MCU. After testing by the NXP app"NTAG I2C demo", I find the speed of pass through mode can only reach 2831Bytes/s， while the guide book said it can reach 5kBytes/s.

I want to know how to speed up.

Hello @Owenking 

Performing operations on SRAM memory with FAST_READ and FAST_WRITE commands, highly improve overall communication speed. But I'd like to know where you see such data 5kBytes/s? Could you share the document NO. ?

[Owenking]

I already use FAST_READ and FAST_WRITE.

The name of document is NT3H2111_2211.pdf. Section 2.6 mentions that the transmission speed can reach 40kbits/s through NFC and I2C interface. Does it mean 5kBytes/s ?

Hello @Owenking 

这个是信号的速率应该需要通过示波器测得，APP显示的是数据流。

所以这意味着APP Demo测出来的就已经是pass through mode的最高速度了？不能再快了吗？

Hello @Owenking 

FAST_WRITE 已经是最快了。
