Overview of AT25640B-SSHL-T

The AT25640B-SSHL-T is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Adesto Technologies. It has a capacity of 64 kilobits (8 kilobytes) and operates with a Serial Peripheral Interface (SPI) protocol. The "SSHL" in the part number indicates its temperature range of operation (-40°C to +85°C). This EEPROM offers non-volatile storage, meaning it retains data even when power is removed. It is designed for use in various electronic devices requiring data storage, such as consumer electronics, industrial equipment, and automotive systems. The "T" in the part number typically denotes the package type, which could vary based on the manufacturer's specifications. With its SPI interface, this EEPROM provides fast read and write operations, making it suitable for applications where quick access to stored data is necessary. Its compact size, low power consumption, and reliability make it a popular choice for embedded systems and other electronic devices
