Features & Applications

The 24AA256/24LC256/ 24FC256 (24XX256*) is a 32 K x 8 (256 Kbit) Serial Electrically Erasable PROM, capable of operation across a broad voltage range (1.8 V to 5.5 V). It has been developed for advanced, low-power applications such as personal communications or data acquisition.

This device also has a page write capability of up to 64 bytes of data. This device is capable of both random and sequential reads up to the 256 K boundary. Functional address lines allow up to eight devices on the same bus, for up to 2 Mbit address space. 

Features:

  • 2-wire serial interface bus, I2C™ compatible
  • Cascadable for up to eight devices
  • Self-timed erase/write cycle
  • 64-byte Page Write mode available
  • 5 ms max. write cycle time
  • Hardware write-protect for entire array
  • Output slope control to eliminate ground bounce
  • Schmitt Trigger inputs for noise suppression
  • Electrostatic discharge protection > 4000 V
  • Data retention > 200 years
