25LC640-I/SN

The 25LC640-I/SN is a 64Kbit serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Microchip Technology. It has a storage capacity of 8,192 bytes organized in 128 pages of 64 bytes each. The EEPROM operates over a wide voltage range from 1.8V to 5.5V, making it suitable for a variety of applications.The 25LC640-I/SN features a high-speed SPI (Serial Peripheral Interface) compatible serial bus interface, allowing for fast data transfer rates. It also has a Write Protect pin to prevent accidental write operations, and a hardware and software write protection feature to safeguard data. The EEPROM has a maximum clock frequency of 5MHz and a typical programming time of 5ms.The 25LC640-I/SN is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package, making it compact and easy to integrate into circuit designs. It is commonly used in applications such as automotive, industrial control, consumer electronics, and networking devices for storing configuration data, calibration values, and other critical information
