大家好,
我正在使用ST
NFC芯片:M24LR16E在我的产品中,我发现一些与市场上的智能
手机不兼容(三星S4,S5,Nexus 4)
我做了一些研究,发现这些手机使用的Broadcom NFC芯片(BC20794)与产品中的某些NFC芯片不兼容。这取决于所使用的NFC标签的类型。 (大多数现有产品都有Mifare Classic 1k标签,它只与恩智浦芯片配备的手机兼容)。
事实上,M24LR16E具有ISO15693标准,与智能手机的NXP NFC芯片(PN544,PN65N ......)的标准相同。而Broadcom芯片中的ISO标准是ISO 18092,ISO14443(来自NFC
论坛1-4类标签)......
所以问题来自于这种不同类型的NFC标签技术(Mifare Classic 1k vs NFC Forum Type 1-4)?或者它来自应用程序?
有人有同样的问题吗?我们需要更换M24LR16E芯片吗?
谢谢您的回答
问候

Hi all,
I am using a ST NFC chip : M24LR16E in my products and I noticed some incompatibility with Smartphones of the market (Samsung S4, S5, Nexus 4)
I have made some research and I found that these phones were using a Broadcom NFC chip (BC20794) which is not compatible with some NFC chips in the product. It depends on the type of NFC tag used. (Most of existing products has Mifare Classic 1k tag and it is just compatible with NXP chip equiped phones).
In fact the M24LR16E has ISO15693 standard, which is the same standard as in the NXP NFC chips of the Smartphones (PN544, PN65N...). Whereas the ISO standards in the Broadcom chips are ISO 18092, ISO14443 (from NFC Forum type 1-4 tags)...
So the problems comes from this different type of NFC tags technology (Mifare Classic 1k vs NFC Forum Type 1-4)? Or is it coming from the application?
Do someone has the same problems? Do we need to change the M24LR16E chips?
Thank you for your answers
Regards
