24C21 - 2-Wire Serial EEPROM

General Description

The AT24C21 provides 1024 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 128 words of 8 bits each.

The device is optimized for use in applications requiring data storage and serial transmission of configuration and control information.

Key Features

  • 2-Wire Serial Interface Schmitt Trigger, Filtered Inputs For Noise Suppression DDC1™/ DDC2™ Interface Compliant for Monitor Identification Low Voltage Operation.
  • 2.5 (VCC = 2.5V to 5.5V) Internally Organized 128 x 8 100 kHz (2.5V) Compatibility 8-Byte Page Write Mode Write Protection Available Self-timed Write Cycle (10 ms max) High Reliability.
  • Endurance: 1 Million Write Cycles.
