Microchip | 24AA256-I/P

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
