Features & Applications
The M34E02-FDW6TP is a 2 Kbit serial presence detect EEPROM for double data rate DRAM modules. This I2C-compatible EEPROM is organized as 256 × 8 bits, able to lock data permanently in its first half (from location 00h to 7Fh). This facility has been designed specifically for use in DRAM DIMMs with serial presence detect (SPD).

All the information concerning the DDR1 or DDR2 configuration of the DRAM module (such as its access speed, size and organization) can be kept write-protected in the first half of thememory.The I2C uses a two-wire serial interface, comprising a bidirectional data line and a clock line. The devices carry a built-in 4-bit device type identifier code (1010) in accordance with the I2C bus definition.

Features:

  • 2 Kbit EEPROM for DDR1 and DDR2 serial presence detect
  • Backward compatible with the M34C02
  • Permanent and reversible software data protection for lower 128 bytes
  • 100 kHz and 400 kHz I2C bus serial interface
  • Single supply voltage: – 1.7 V to 5.5 V
  • Byte and Page Write (up to 16 bytes)
  • Self-timed write cycle
  • Noise filtering
    • Schmitt trigger on bus inputs
    • Noise filter on bus inputs
  • Enhanced ESD/latch-up protection
  • More than 1 million erase/write cycles
  • More than 40 years’ data retention
  • ECOPACK® (RoHS compliant) packages
  • Packages:
    • ECOPACK2® (RoHS-compliant and Halogen-free)
