The AT25256W-10SI-1.8 is a 256Kbit serial EEPROM that operates with a supply voltage range of 1.8V to 5.5V. It features a Serial Peripheral Interface (SPI) compatible with modes 0 and 3, allowing for a clock rate of up to 3 MHz. The memory is organized as 32,768 words of 8 bits each and supports both 64-byte page mode and byte write operations. Data protection is enhanced through block write protection options, which can protect 1/4, 1/2, or the entire memory array. The device includes a write protect (WP) pin and supports self-timed write cycles with a typical duration of 5 ms. It boasts high reliability with an endurance of 100,000 write cycles and a data retention period exceeding 200 years. The AT25256W-10SI-1.8 is available in various package types, including an 8-lead SOIC, making it suitable for space-constrained applications. It is also rated for industrial temperature ranges from -40¬8C to 85¬8C, ensuring performance in demanding environments.
