M24LR04E-RMN6T/2 (STMICROELECTRONICS)

The M24LR04E-RMN6T/2 is a dynamic NFC/RFID Tag IC with a dual-interface and 4kb electrically erasable programmable memory (EEPROM). It features an I?C interface and can be operated from a VCC power supply. It is also a contactless memory powered by the received carrier electromagnetic wave. The IC is organized as 512 x 8-bit in the I?C mode and as 128 x 32-bit in RF mode. It also features an energy harvesting analogue output, as well as a user configurable digital output pin toggling during either RF write in progress or RF busy mode. The device behaves as a slave in the I?C protocol, with all memory operations synchronized by the serial clock. Read and write operations are initiated by a start condition, generated by the bus master.
