NT3H1101W0FHKH

RFID应答器 NTAG I2C NFC Forum type 2 Tag compliant

NTAG I2C - Energy harvesting NFC Forum Type 2 Tag with field detection pin and I2C interface

General description NT3H1101W0FHKH

NTAG I2C - The entry to the NFC world: simple and lowest cost. The NTAG I2C is the first product of NXP’s NTAG family offering both contactless and contact interfaces. In addition to the passive NFC Forum compliant contactless interface, the IC features an I2C contact interface, which can communicate with a microcontroller if the NTAG I2C is powered from an external power supply. An additional externally powered SRAM mapped into the memory allows a fast data transfer between the RF and I2C interfaces and vice versa, without the write cycle limitations of the EEPROM memory.

Key features NT3H1101W0FHKH

 RF interface NFC Forum Type 2 Tag compliant

 I2C interface

 Configurable field detection pin based on open drain implementation that can be triggered upon the following events:

 RF field presence

 First start of communication

 Selection of the tag only

 64 byte SRAM buffer for fast transfer of data (Pass-through mode) between the RF and the I2C interfaces located outside the User Memory

 Wake up signal at the field detect pin when:

 New data has arrived from one interface

 Data has been read by the receiving interface

RF interface NT3H1101W0FHKH
