The 25LC1024-E/MF is a 1024-Kbit serial EEPROM memory that communicates via a Serial Peripheral Interface (SPI) compatible bus. It operates over a wide voltage range of 2.5V to 5.5V and supports a maximum clock speed of 20 MHz for fast data access. Key features include a 256-byte page size, a maximum write cycle time of 6 ms, and self-timed erase cycles. This model is specified for the extended temperature range of -40°C to +125°C. With high endurance of 1 million erase/write cycles and data retention exceeding 200 years, it provides a highly reliable non-volatile memory solution for data logging, configuration storage, and other embedded applications.
