STM M24LR04E-R 4-Kbit dual interface EEPROM with RFID
STMicroelectronics has introduced the M24LR04E-R 4-Kbit Dual Interface EEPROM with RFID. “The M24LR04E-R device is a dual-interface, electrically erasable programmable memory (EEPROM). It features an I2C interface and can be operated from a VCC power 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.” This device operates on a single supply voltage between 1.8 – 5.5 volts when using the I2C interface, with RFID operation harvesting energy from the reader device.
Single unit retail pricing on the 8-pin TSSOP package is in the $1.50 range from DigiKey.
