Working Principles

The CAT28F020GI-12T utilizes a floating gate transistor structure to store data. It employs a combination of electrical charges to represent binary information, allowing for non-volatile storage even when power is removed.

During write operations, the IC applies high voltages to specific memory cells, altering the charge on the floating gate and thereby modifying the stored data. Reading data involves detecting the charge state of each memory cell, providing the desired information to the system.

Detailed Application Field Plans

The CAT28F020GI-12T finds applications in various electronic devices, including but not limited to: - Embedded systems - Consumer electronics - Automotive electronics - Industrial control systems - Communication devices

Its reliable data storage capabilities make it suitable for applications requiring non-volatile memory with moderate storage capacity.
