It operates on a supply voltage range of 2.5V to 5.5V and supports a wide temperature range from -40°C to +85°C. The device utilizes the Serial Peripheral Interface (SPI) for communication and features a write protect pin for data security.

Detailed Pin Configuration

The 93C76CT-E/SN follows a standard 8-pin SOIC package configuration. The pins are labeled as follows:

1. Chip Select (/CS): Enables communication with the IC.
2. Serial Clock (SCK): Provides the clock signal for data transfer.
3. Serial Data Input (SI): Receives data from the external device.
4. Serial Data Output (SO): Transmits data to the external device.
5. Write Protect (/WP): Controls write protection of the memory.
6. VCC: Power supply input (2.5V to 5.5V).
7. Ground (GND): Common ground reference.
8. Serial Data Out (NC): No connection.

Functional Features

• Non-volatile Storage: The 93C76CT-E/SN retains data even when power is removed.
• Electrically Erasable and Programmable: Allows for easy modification of stored data.
• High-Density Storage: Offers 8 kilobits of memory capacity.
• SPI Interface: Utilizes the Serial Peripheral Interface for communication.
• Write Protection: Provides a write protect pin for enhanced data security.

Advantages and Disadvantages

Advantages: - Non-volatile memory ensures data retention. - Electrically erasable and programmable for easy data modification. - Compact SOIC package allows for space-efficient integration. - Wide operating temperature range enables usage in various environments.

Disadvantages: - Limited storage capacity compared to other EEPROM variants. - Requires an external microcontroller or device for communication.

Working Principles

The 93C76CT-E/SN operates by utilizing electrically controlled floating gate transistors to store and retrieve data. When data is written, the charge on the floating gate is altered, representing either a "0" or a "1." The stored data can be erased and reprogrammed electrically, allowing for flexibility in data manipulation.
