Data Sheets:

The 24CW64X provide 64Kbits of Serial EEPROM utilizing an I2C (2-wire) serial interface. It is organized as 8192 bytes of 8 bits each (8 Kbytes). The 24CW Series is optimized for use in consumer and industrial applications, where reliable and dependable nonvolatile memory storage is essential. The 24CW Series allows up to eight devices to share a common I2C (2-wire) bus and is capable of operation across a broad voltage range (1.6V to 5.5V).

The 24CW Series contains a pair of programmable Configuration registers which allow certain device behaviors to be modified. These registers are the Write Protection Register and the Hardware Address Register.



  • Internally organized as one 8192 x 8 bit block
  • Byte or page writes up to 32 bytes
  • Byte or sequential reads within a block
  • Self-timed write cycle (5ms maximum) High-Speed I2C Interface
  • Industry standard: 1MHz, 400kHz and 100 kHz
  • Configurable via the Hardware Address Register (HAR)
  • Software write protection via the Write Protection Register (WPR)
  • Write current: 1.0 mA maximum at 5.5V
  • Read current: 1.0 mA maximum at 5.5V, 1 MHz
  • More than one million erase/write cycles
  • ESD protection:>4000V RoHS Compliant
  • AEC-Q100 Qualified - Grade 1 (-40C to +125C)
