┌───┬───┐ │ 1 │ 8 │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ 4 │ 5 │ └───┴───┘

1. Chip Select (CS): Enables communication with the IC
2. Serial Clock (SCK): Provides timing for data transfer
3. Serial Data Input (SDI): Receives data from the microcontroller
4. Ground (GND): Reference voltage
5. Serial Data Output (SDO): Transmits data to the microcontroller
6. Write Protect (WP): Protects memory from accidental writes
7. VCC: Power supply voltage
8. Serial Data Out (SDO): Same as pin 5

Functional Features

• Non-volatile memory: Retains data even without power
• Serial interface: Uses I2C bus for communication
• Small form factor: DIP-8 package allows for easy integration
• Low power consumption: Suitable for battery-powered devices
• Write protection: Prevents accidental modification of stored data

Advantages and Disadvantages

Advantages: - Compact size and low power consumption - High write endurance and long data retention period - Easy integration with microcontrollers using the I2C interface

Disadvantages: - Limited storage capacity (1K bits) - Relatively slower data transfer rate compared to other memory types

Working Principles

The NM93CS46N is a serial EEPROM that utilizes non-volatile memory technology. It stores digital information in a series of memory cells, which can be electrically programmed and erased. The IC communicates with a microcontroller through the I2C bus, allowing for easy read and write operations. The stored data remains intact even when the power supply is disconnected.
