The AT24C08B-SNHT is an 8K (1024 x 8) Serial EEPROM (Electrically Erasable Programmable Read-Only Memory) from Microchip Technology (formerly Atmel). It features a simple I2C (2-wire) serial interface for communication with microcontrollers and other digital systems. The device is optimized for low-power and low-voltage operation, making it ideal for a wide range of embedded applications.

Applications:

• Consumer electronics
• Industrial control systems
• Data logging
• Configuration storage
• Smart cards
• Metering
• Set-top boxes

Features:

• 8K (1024 x 8) EEPROM
• I2C (2-wire) serial interface
• Low-voltage operation (1.8V to 5.5V)
• Low power consumption
• Write protect pin for hardware data protection
• Self-timed write cycle
• High reliability
• 8-pin SOIC package

Benefits:

• Non-volatile memory: Retains data even when power is removed.
• Easy to use: The I2C interface simplifies communication with microcontrollers.
• Low power consumption: Extends battery life in portable devices.
• Write protection: Prevents accidental data corruption.
• High reliability: Ensures data integrity over a long lifetime.

The AT24C08B-SNHT utilizes a 2-wire serial interface consisting of a serial data line (SDA) and a serial clock line (SCL). Data is transmitted serially, bit by bit, between the device and the microcontroller. The device supports multiple device addressing, allowing multiple EEPROMs to share the same I2C bus. The write protect (WP) pin provides hardware data protection, preventing accidental writes to the memory. The EEPROM features a self-timed write cycle, simplifying programming and reducing the need for external timing circuitry. It operates over a wide temperature range, making it suitable for various environmental conditions. Typical applications include storing configuration parameters, user preferences, and calibration data.
