24C16 16Kbit EEPROM Memory Integrated Circuit - High-Reliability Serial Electrically Erasable Programmable Read-Only Memory with I2C Interface for Non-Volatile Data Storage in Embedded Systems The 24C16 is a high-reliability serial EEPROM (Electrically Erasable Programmable Read-Only Memory) integrated circuit providing 16Kbit of non-volatile storage capacity for persistent data retention in embedded systems, microcontroller-based designs, IoT devices, automotive electronics, and consumer appliances. This advanced memory IC utilizes the industry-standard I2C (Inter-Integrated Circuit) two-wire interface for efficient communication with microcontrollers and processors, enabling simple integration while minimizing pin count requirements on host devices. Unlike volatile memory types that lose stored information when power is removed, the 24C16 maintains data integrity for over 40 years without requiring any power, making it ideal for storing critical configuration parameters, calibration data, device serial numbers, user preferences, and event logs that must persist across power cycles. The memory cells endure more than one million write/erase cycles, ensuring long-term reliability even in applications requiring frequent data updates. The I2C interface operates at standard (100kHz) and fast (400kHz) bus speeds, accommodating various system timing requirements while maintaining compatibility with the broad ecosystem of microcontrollers supporting I2C communication. The two-wire interface consisting of Serial Data (SDA) and Serial Clock (SCL) lines simplifies PCB routing compared to parallel memory interfaces, reducing board complexity and manufacturing costs. Multiple devices can share the same I2C bus through device addressing, conserving valuable I/O pins on the host microcontroller. Operating voltage flexibility allows the 24C16 to function reliably across supply voltages from 1.8V to 5.5V, supporting both modern low-voltage microcontrollers and legacy 5V systems without requiring level shifting circuitry. The wide operating temperature range from -40°C to +85°C ensures reliable operation in industrial environments, automotive applications, and outdoor installations subject to temperature extremes. The SMD package option provides compact footprint suitable for space-constrained modern electronics while maintaining excellent thermal characteristics and manufacturability. The RoHS-compliant lead-free construction meets international environmental standards while ensuring solder joint reliability through various assembly processes. Standardized pinouts enable second-sourcing and supply chain flexibility for production designs.
