Working Principles

The CAT28LV64WI20 utilizes a technology called Electrically Erasable Programmable Read-Only Memory (EEPROM). It stores data by trapping electric charges within its memory cells, which can be erased and reprogrammed electrically. When data is written, the charges are distributed within the memory cells, and they remain trapped until erased or rewritten.

Detailed Application Field Plans

The CAT28LV64WI20 finds applications in various electronic devices that require non-volatile data storage, such as: - Microcontrollers - Embedded systems - Industrial control systems - Automotive electronics - Consumer electronics
