• Consumer electronics
• Industrial equipment
• Set-top boxes
• Security systems
• Smart cards

Features:

• 4 Kbit (512 x 8) EEPROM
• I2C Serial Interface
• Low-voltage operation
• Write Protect pin
• High reliability
• Low power consumption
• Page Write Mode

Benefits:

• Non-volatile storage: Data is retained even when power is removed.
• Easy to interface: I2C interface simplifies communication with microcontrollers.
• Low power: Suitable for battery-powered applications.
• Small size: Minimizes board space requirements.
• Write protection: Prevents accidental data corruption.

Additional Details:

The AT24HC04BN-SH utilizes a 2-wire I2C serial interface for communication, making it easy to integrate with microcontrollers. It features a write protect pin, which can be used to prevent accidental data overwrites. It supports a page write mode, which allows for writing multiple bytes in a single operation, improving write performance. The device offers high endurance, with a typical rating of 1 million write cycles, and a long data retention period. Operating temperature ranges typically from -40°C to +85°C. The device is commonly used in applications where small amounts of non-volatile data storage are required, such as storing configuration parameters or serial numbers.
