Introduction


M24LR64
Dual Interface EEPROMs M24LR64 from STMicroelectronics ( M24LRxx ) are an innovative family of memories that provides new features and capabilities.
The EEPROM memory bank can be accessed either by a standard I²C interface or by an ISO 15693 RF interface operating at 13.56 MHz.
In this way, you can remotely update electronic product parameters anytime during their lifetime, anywhere in the supply chain or at the end user.
Based on two proven industry-standard interfaces ( M24 & RFID ISO 15693 ), Dual Interface EEPROM products also feature a unique and flexible data protection scheme that protects some or all of the information contained in the memory.
In addition, the family features a 32-bit password protection mechanism.

Key features and benefits

I²C interface
          Industry standard: compatible with most microcontrollers and ASICs
          1.8 to 5.5 V: wide operating voltage range enabling large spectrum of applications
          400 kHz across the entire voltage range
ISO 15693 RF interface
          Industry standard: compatible with ISO 15693 readers
          RF read and write access to the Dual Interface EEPROM
          Passive RFID technology: no energy needed to operate in RF mode
Memory
          User memory: 64 Kbits of EEPROM
          Reliability: 40 years data retention, 1 million erase-write cycles
          Data protection: unique and flexible 32-bit password protection scheme
64-bit unique identifier (UID)



M24LR16
The M24LR16E-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 M24LR16E-R is organized as 2048 × 8 bits in the I2C mode and as 512 × 32 bits in the ISO 15693 and ISO 18000-3 mode 1 RF mode.
The M24LR16E-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.

Tools

There are different tools that you find here.
The suggested low cost tool for reading and writing memory is: STARTER KIT-M24LR-A
The STARTKIT-M24LR-A is a starter kit for ST Dual Interface EEPROM products which allows system designers to evaluate simply the main M24LR64-R RF and I2C features.
The suggested low cost M24LR64 eva-board is: ANT1-M24LR-A
The ANT1-M24LR-A antenna reference board is a ready-to-use PCB that features an M24LR64-R Dual Interface EEPROM IC connected to a 45 mm x 75 mm 13.56 MHz etched RF antenna on one side, and to an I2C bus on the other side.
The ultra small antenna for M24LR64 eva-board is: ANT3-M24LR-A
The ANT3-M24LR-A antenna reference board is a ready-to-use PCB that features an M24LR64-R Dual Interface EEPROM IC connected to a 4.7 μH SMD inductor on one side, and to an I2C bus on the other side. The SMD inductor acts as a 13.56 MHz RF antenna.
