The AT24C08BN is an 8-Kbit (1024 x 8) Serial EEPROM (Electrically Erasable Programmable Read-Only Memory) from Microchip Technology (formerly Atmel). This device features a 2-wire serial interface, allowing for easy integration into various systems that require non-volatile memory for storing configuration data, user preferences, or other types of data that must be retained even when power is removed.

Applications

• Consumer Electronics: Used for storing user preferences and settings in TVs, set-top boxes, and other consumer devices.
• Industrial Control Systems: Employed for storing calibration data and configuration parameters in industrial equipment.
• Automotive Electronics: Utilized for storing diagnostic information and vehicle settings in automotive control units.
• Medical Devices: Used for storing device configuration and patient data in medical equipment.
• Networking Equipment: Integrated into routers, switches, and other networking devices for storing configuration data.

Features

• 8-Kbit (1024 x 8) EEPROM: Provides 8192 bits of non-volatile memory.
• 2-Wire Serial Interface: Uses the I2C (Inter-Integrated Circuit) protocol for communication.
• Low Voltage Operation: Operates from a single power supply, typically in the range of 1.8V to 5.5V.
• Write Protection: Features a hardware write protect pin to prevent accidental data corruption.
• High Endurance: Supports a high number of write cycles, typically 1 million cycles per byte.

Benefits

• Non-Volatile Memory: Retains data even when power is removed, ensuring data integrity.
• Easy Integration: The 2-wire serial interface simplifies the integration process into various systems.
• Low Power Consumption: Minimizes power usage, making it suitable for battery-powered applications.
• Data Protection: The write protect feature prevents accidental overwriting of critical data.

Additional Details

The AT24C08BN is available in various package options, including DIP (Dual In-Line Package), SOIC (Small Outline Integrated Circuit), and TSSOP (Thin Shrink Small Outline Package), to accommodate different application requirements. The I2C interface supports standard (100 kHz) and fast (400 kHz) modes, providing flexibility in communication speed. The device also features a page write mode, allowing for efficient writing of multiple bytes in a single operation. The AT24C08BN is designed for use in a wide range of operating temperatures, typically from -40°C to +85°C, making it suitable for use in harsh environments. Its compact size and low power consumption make it an ideal choice for applications where space and power are limited.
