Working Principles

The AT27BV1024-90VC utilizes a combination of floating-gate transistors and control circuitry to store and retrieve digital information. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be removed during an erase operation, allowing the transistor to return to its original state. The stored charges determine the logic state of each memory cell, which can be read by applying appropriate voltage levels to the pins.

Detailed Application Field Plans

The AT27BV1024-90VC finds applications in various electronic systems, including but not limited to: - Embedded systems - Consumer electronics - Automotive electronics - Industrial control systems - Communication devices
