Product Overview
The AT24C256C-XHL-B is a 262144-bit standard I²C serial Electrically Erasable Programmable Read-Only Memory (EEPROM) organized as 32768 words of 8-bit each. The device cascading feature allows up to eight devices to share a common 2-wire bus. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential.
- Low and standard-voltage operation
 - 2-wire serial interface
 - Schmitt trigger, filtered inputs for noise suppression
 - Bidirectional data transfer protocol
 - Write protect pin for hardware data protection
 - Self-timed write cycle (5ms maximum)
 - High-reliability
 - Endurance - 1000000 write cycles
 - Data retention - 40 years
 - Green product and no Sb/Br
