N24RF04E数据手册RF/IF射频/中频RFID的RFID射频接入监控IC规格书PDF

描述 Description

The N24RF04E is a RFID/NFC tag with a 4 Kb EEPROM device, offering both contactless and contact interface. In addition to the ISO/IEC 15693 radio frequency identification (RFID) interface protocol, the device features an I2C interface to communicate with a microcontroller. The I2C contact interface requires an external power supply.
The 4 Kb EEPROM array is internally organized as 128 x 32 bits in RF mode and as 512 x 8 bits when accessed from the I2C interface.
