Working Principles

The 93C76AT-I/ST is based on Electrically Erasable Programmable Read-Only Memory (EEPROM) technology. It utilizes a floating gate transistor structure to store and retrieve data. When data needs to be written, an electrical charge is applied to the floating gate, altering its threshold voltage. This change in threshold voltage represents the stored data. To read the data, the threshold voltage is measured and interpreted as either a logic high or low.

Detailed Application Field Plans

The 93C76AT-I/ST IC finds applications in various electronic devices that require non-volatile memory storage. Some potential application fields include: - Consumer electronics (e.g., smartphones, tablets, digital cameras) - Automotive systems (e.g., engine control units, infotainment systems) - Industrial automation (e.g., programmable logic controllers, sensors) - Medical devices (e.g., patient monitoring systems, diagnostic equipment)
