25AA256-I/SN – proven EEPROM memory in a compact SOIC package

5AA256 is an EEPROM (Electrically Erasable Programmable Read-Only Memory) with a capacity of 256 kilobits, which equals 32 kilobytes of data. It is non-volatile memory, meaning it retains data even when power is removed. The chip communicates via the SPI (Serial Peripheral Interface), enabling simple and fast communication with microcontrollers, microprocessors, or other digital devices. The 25AA256-I/SN is a universal and easy-to-use SPI EEPROM memory, ideal for applications where a durable, compact data storage with fast access is required. Its low operating voltage and industrial temperature range make it highly versatile and reliable.
