EEPROM 4 click is 2,097,152 bits on a click board™, organized into 262,144 bytes. In other words, this click board™ is an EEPROM memory medium with the capacity of 256 KB. The used EEPROM module has very good endurance and it can withstand 1,000,000 write cycles, with the data retaining period of about 40 years. The EEPROM module on this click can work with power supply voltage ranging from 1.7V to 5.5V, it features the self-timed write cycles, doesn't require erase before writing, has a dedicated write protect pin for hardware protection of stored data, and has a dedicated hold pin used for holding the data transfer.

EEPROM 4 click is aimed towards industrial and commercial applications, which require low voltage and low power operational capabilities. It can be used for any kind of temporary or permanent data storage for various embedded electronic devices, simple data logging, storing various working parameters of a module or device, safeguarding the sensitive data in case of a power cycle, and other similar applications where EEPROM memory is needed.
