M24LR04E-R 4-Kbit Dual Interface EEPROM with password protection, energy harvesting and RF status functions
The M24LR04E-R device is a dual-interface, electrically erasable programmable memory (EEPROM). It features an I²C interface and can be operated from a VCCpower supply. It is also a contactless memory powered by the received carrier electromagnetic wave. The M24LR04E-R is organized as 512 × 8 bits in the I²C mode and as 128 × 32 bits in RF mode.
The M24LR04E-R also features an energy harvesting analog output, as well as a user-configurable digital output pin toggling during either RF write in progress or RF busy mode
