概述

Description

M24LR64-RMN6T/2 is a STMicroelectronics 64 Kbit dual‑interface EEPROM. It combines two communication paths:
- I2C serial interface for a microcontroller
- NFC/RFID interface (ISO/IEC 15693) for contactless access
Key points:
- Memory: 64 Kbit (8 kB) of non‑volatile EEPROM shared between the two interfaces
- Power: can be powered from the I2C supply or energy harvested from the NFC field (no battery needed)
- Security: supports write/read protection and password features to guard memory
- Packaging: RMN6T/2 variant for compact, surface‑mount use
- Applications: NFC tags with writable memory, asset tracking, product authentication, smart posters, and NFC-enabled devices
In short, M24LR64-RMN6T/2 lets a host MCU update memory via I2C while an NFC reader can access the same data in RF mode, making it ideal for dual‑interface NFC/tag applications.

Features

Here are the key features of M24LR64-RMN6T/2:
- 64 kbit dynamic NFC/RFID tag with dual interfaces (I2C and NFC RF)
- I2C interface for host MCU and 13.56 MHz NFC RF interface (ISO/IEC 14443 Type A)
- Powering: energy from NFC field (no battery) and/or I2C supply
- Memory: 64 kbit total (accessible via both interfaces), with dedicated NDEF/user areas
- NFC/NDEF support for easy smartphone/app integration
- Security: password (PWD) and PACK authentication, read/write protection, and memory locking
- Unique ID for anti-collision and secure identification
- Small 8-pin package in RMN6T/2; industrial temperature range (typical -40°C to 85°C)
- Applications: asset tracking, access control, smart packaging/posters, product authentication
Note: exact memory organization and voltage ranges are per datasheet; confirm for your design needs.

Package

The M24LR64-RMN6T/2 is supplied in an 8‑lead SO (SO‑8) surface-mount plastic package (SMD), RoHS-compliant.

Pinout

The M24LR64‑RMN6T/2 is a 6‑pin device. Pin functions (high level):
- VDD: positive supply (power).
- VSS (GND): ground.
- SCL: I²C clock input.
- SDA: I²C data (bidirectional).
- RF1 and RF2: contactless RF/antenna interface pins for NFC/RFID operation.
(VDD/VSS power the I²C and memory core; SDA/SCL provide the wired I²C interface; RF1/RF2 connect to the antenna for the contactless interface.)

Manufacturer

Manufacturer: STMicroelectronics (ST).
What kind of company: STMicroelectronics is a multinational semiconductor manufacturer that designs, develops and produces integrated circuits, discrete semiconductors, sensors and related electronics for automotive, industrial, consumer and communications markets.
