The AT24C16C-SSHM is a 16K (2048 x 8) Serial EEPROM (Electrically Erasable Programmable Read-Only Memory) from Microchip Technology (formerly Atmel). It utilizes a 2-wire I2C serial interface for easy communication with microcontrollers and other digital systems. Designed for low-power and low-voltage operation, the AT24C16C-SSHM is well-suited for diverse embedded applications where non-volatile data storage is required.

Applications:

• Consumer electronics (e.g., set-top boxes, TVs, DVD players)
• Industrial control systems
• Medical devices
• Automotive electronics
• Data logging
• Configuration storage
• Smart cards

Features:

• 16K (2048 x 8) EEPROM
• I2C (2-wire) serial interface
• Low-voltage operation (1.7V to 5.5V)
• Low power consumption
• Write protect pin for hardware data protection
• Page write mode
• High reliability with endurance of 1 million write cycles
• 8-pin SOIC package

Benefits:

• Non-volatile storage: Data is preserved even when power is off, ensuring long-term data retention.
• Simple interface: The I2C interface simplifies integration with microcontrollers and reduces system complexity.
• Low power: Suitable for battery-powered and energy-sensitive applications.
• Data protection: The write protect feature prevents accidental data modification.
• Fast write times: Page write mode allows for efficient data storage.

The AT24C16C-SSHM communicates via the standard I2C protocol, employing a serial data (SDA) and a serial clock (SCL) line. The device supports a range of operating voltages, making it versatile for different system requirements. A hardware write protect (WP) pin enables complete memory protection. The page write mode allows writing multiple bytes in a single operation, improving write performance. The EEPROM is specified for a high number of write cycles, ensuring data integrity over the device's lifespan. Typical usage includes storing user preferences, system configurations, calibration parameters, and sensor data in various embedded systems. The SOIC package facilitates easy surface mounting on PCBs.
