AT25256W-10SI-2.7, 256-Kbit Serial EEPROM, SPI Interface, SOIC-8

The AT25256W-10SI-2.7 is a 256-Kbit serial EEPROM designed for high-reliability, low-power applications requiring non-volatile data storage. It features an SPI (Serial Peripheral Interface) bus, allowing for fast and efficient communication with microcontrollers and other embedded devices.

The memory is organized as 32K x 8-bit, providing ample space for firmware, configuration data, and user preferences. Its wide operating voltage range (2.7V - 5.5V) ensures compatibility with both low-power and standard voltage systems. The device supports SPI Modes 0 and 3, making it easy to interface with industry-standard microcontrollers.

For data protection, the AT25256W-10SI-2.7 includes a write protection (WP) pin, programmable block protection, and write disable instructions, ensuring secure and controlled data modification. The EEPROM supports self-timed write cycles (5ms typical) and high endurance of 100,000 write/erase cycles per sector with a 100-year data retention period.

Encased in a compact SOIC-8 package, this EEPROM is ideal for automotive, industrial automation, consumer electronics, and embedded applications where secure and reliable memory storage is required.
