Working Principles

The AT27C080-15TI operates based on the principle of electrical charge trapping. During programming, a high voltage is applied to the appropriate address and data lines, causing electrons to be trapped in the floating gate of the memory cell. This trapped charge represents the stored data. During read operations, the presence or absence of charge in the floating gate determines the output state of each memory cell.

Detailed Application Field Plans

The AT27C080-15TI finds applications in various fields where non-volatile memory is required. Some potential application areas include: - Embedded systems - Automotive electronics - Industrial control systems - Medical devices - Consumer electronics
