Working Principles

The AT28C64X-20SC utilizes a combination of floating-gate transistors and control circuitry to store and retrieve digital information. When data is written, the control circuitry applies a high voltage to the selected memory cell, causing electrons to be trapped in the floating gate. This trapped charge alters the transistor's behavior, representing a binary value (0 or 1). During read operations, the control circuitry detects the transistor's behavior to retrieve the stored data.

Detailed Application Field Plans

The AT28C64X-20SC finds applications in various electronic systems, including but not limited to: - Embedded systems - Microcontrollers - Industrial automation - Automotive electronics - Consumer electronics
