Frequently Asked Questions
What memory capacity and organization does the M24LR04E-RMC6T/2 have?
The M24LR04E-RMC6T/2 provides 4096 bits (4-Kbit) of EEPROM organized as 128 words of 32 bits each. This dual-width memory architecture allows efficient 32-bit RF access and standard 8-bit I2C byte access, making it versatile for both NFC tag data and microcontroller-driven EEPROM storage applications.
What RF interface standard does the M24LR04E-RMC6T/2 use and what is the read range?
The M24LR04E-RMC6T/2 is compliant with ISO 15693 (vicinity card) RF standard operating at 13.56 MHz. This standard supports read distances of up to approximately 1 meter depending on antenna design and reader power, making it suitable for industrial RFID and NFC applications requiring greater range than ISO 14443 devices.
Can the M24LR04E-RMC6T/2 be accessed via I2C and RF simultaneously?
Yes, the M24LR04E-RMC6T/2 supports simultaneous RF and I2C access with built-in arbitration to manage concurrent operations safely. The I2C interface operates up to 400kHz (fast mode), and the device provides mailbox and energy harvesting features enabling real-time data transfer between an RF reader and an I2C host microcontroller.
Does the M24LR04E-RMC6T/2 support energy harvesting and how does it work?
Yes, the M24LR04E-RMC6T/2 includes an energy harvesting output pin (Vout) that rectifies power from the RF electromagnetic field and provides a DC voltage to supply external low-power components. This enables battery-less operation of small sensors or microcontrollers when an NFC reader is in proximity, making it excellent for passive IoT and smart label designs.
What package and operating temperature range does the M24LR04E-RMC6T/2 support?
The M24LR04E-RMC6T/2 is available in an 8-pin SO8N small outline package (JEDEC R-PDSO-N8) with a compact footprint suitable for PCB integration. It operates over an industrial temperature range, and the factory lead time is approximately 13 weeks for standard orders. The device is RoHS compliant and suitable for automated SMT assembly processes.
