M24LR04E-RDW6T/2
4-Kbit Dual Interface EEPROM with password protection, energy harvesting and RF status functions, TSSOP8, STM, RoHS

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.

Features:

  • I2C interface
    • Two-wire I2C serial interface supports 400 kHz protocol
    • Single supply voltage:
      • 1.8 V to 5.5 V
    • Byte and Page Write (up to 4 bytes)
    • Random and Sequential read modes
    • Self-timed programming cycle
    • Automatic address incrementing
    • Enhanced ESD/latch-up protection
    • I²C timeout
  • Contactless interface
    • ISO 15693 and ISO 18000-3 mode 1 compatible
    • 13.56 MHz ±7k Hz carrier frequency
    • To tag: 10% or 100% ASK modulation using 1/4 (26 Kbit/s) or 1/256 (1.6 Kbit/s) pulse position coding
    • From tag: load modulation using Manchester coding with 423 kHz and 484 kHz subcarriers in low (6.6 kbit/s) or high (26 kbit/s) data rate mode. Supports the 53 kbit/s data rate with Fast commands
    • Internal tuning capacitance: 27.5pF
    • 64-bit unique identifier (UID)
    • Read Block & Write (32-bit blocks)
  • Digital output pin
    • User configurable pin: RF write in progress or RF busy mode
  • Energy harvesting
    • Analog pin for energy harvesting
    • 4 sink current configurable ranges
  • Memory
    • 4-Kbit EEPROM organized into:
      • 512 bytes in I2C mode
      • 128 blocks of 32 bits in RF mode
    • Write time
