Features

• 2-wire serial interface
• Low-voltage operation
• Low power consumption
• Write protect feature
• Self-timed write cycle

Benefits

• Simple interface simplifies system design
• Reduces power consumption in battery-powered applications
• Protects data from accidental overwrites
• Eliminates the need for external timing components
• Provides reliable non-volatile memory storage

Additional Details

The 24LC16B operates from a single supply voltage, typically ranging from 2.5V to 5.5V. It supports the standard I2C protocol, allowing for easy integration with microcontrollers and other devices. The device features a write protect pin that can be used to prevent accidental overwrites of memory. It has a self-timed write cycle, eliminating the need for external timing components. The 24LC16B is available in various package options, including SOIC, TSSOP, and DIP. It typically guarantees a data retention time of at least 10 years.
