Working Principles

The 93LC76C-I/ST utilizes a floating-gate transistor technology to store data in its memory cells. When data is written, an electrical charge is trapped in the floating gate, altering the transistor's behavior. This charge can be retained for long periods, allowing the chip to retain data even when power is removed. The serial interface facilitates communication between the chip and the controlling microcontroller.

Detailed Application Field Plans

The 93LC76C-I/ST is commonly used in various electronic devices that require non-volatile memory storage, such as: - Consumer electronics (e.g., TVs, set-top boxes, remote controls) - Automotive systems (e.g., engine control units, infotainment systems) - Industrial equipment (e.g., sensors, control modules) - Medical devices (e.g., patient monitors, diagnostic equipment)
