Microchip Technology's 25LC640X-E-ST is a 64-kilobit Serial EEPROM utilizing advanced CMOS technology. This device offers an 8K x 8 memory organization and supports the SPI serial bus interface, operating at clock frequencies up to 3.0 MHz. Engineered for robust data integrity, it boasts an endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years. The 25LC640X-E-ST operates across a wide temperature range of -40°C to +125°C and requires a supply voltage from 4.5V to 5.5V. It is housed in a compact, surface-mountable 8-lead TSSOP package (PDSO8) with a 0.65mm terminal pitch. Write protection is available through both hardware and software mechanisms. This component finds application in industrial control systems, automotive electronics, and consumer devices requiring non-volatile data storage.
