Key Features

  • 16/32/64/128-Kbit EEPROM: - Internally organized as one 2048/4096/8192/16384 x 8-bit block - Byte or page writes up to 32 bytes - Byte or sequential reads within a block - Self-timed write cycle (5 ms maximum).
  • High-Speed I2C Interface: - Industry standard: 1 MHz, 400 kHz and 100 kHz - Output slope control to eliminate ground bounce - Schmitt trigger inputs for noise suppression.
  • Programmable Hardware Client Address Bits: - Configurable via the Hardware Address Regist.
