N24RF64

N24RF64 Dual Interface RFID 64 Kb EEPROM Tag ISO 15693 RF and I2C Bus Compliant Description The N24RF64 is a RFID/NFC tag with a 64 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 64 Kb EEPROM array is internally organized as 2048 x 32 bits in RF mode and as 8192 x 8 bits when accessed from the I2C interface. Features Contactless Transmission of Data ISO 15693 / ISO 18000−3 Mode1 Compliant ♦ Vicinity Range Communication (up to 150 cm) ♦ Air Interface Communication at 13.56 MHz (HF) ♦ To tag: ASK Modulation with 1.65 Kbit/s or 26.48 Kbit/s Data Rate ♦ From Tag: Load Modulation Using Manchester Coding with 423 kHz and 484 kHz Subcarriers in Low (6.6 Kbit/s) or high (26 Kbit/s) Data Rate Mode. Supports the 53 Kbit/s Data Rate with Fast Commands Read & Write 32−bit Block Mode Anti−collision Support Security: ♦ 64−bit Unique Identifier (UID) ♦ Multiple 32−bit Passwords and Lock Feature for Each User Memory Sector Supports Fast (400 kHz) and Fast−Plus (1 MHz) I2C Protocol 1.8 V to 5.5 V Supply Voltage Range 4−Byte Page Write Buffer I2C Timeout Schmitt Triggers and Noise Suppression Filters on I2C Bus Inputs (SCL and SDA) 2048 Blocks x 32 Bits (64 Sectors of 32 Blocks Each): RF Mode 8192 x 8 Bits I2C Mode 2,00...
