X25040SI – SPI Interface & Reliable EEPROM Storage

The X25040SI is a 4Kb EEPROM designed for reliable, low-power data storage. It uses a standard SPI interface for fast and simple communication with microcontrollers. Built for embedded systems, the X25040SI offers byte-level write access and strong data retention over time. Its small 8-pin SOIC package supports space-constrained designs without sacrificing durability. Commonly used in configurations, calibration storage, and portable devices, it performs well across a range of temperatures. With consistent read/write cycles and stable operation, the X25040SI is ready for long-term use. Order the X25040SI now from Florida Circuit and secure the memory your project needs.
