• Clock Frequency: Up to 400 kHz (I²C Fast Mode)
• Package Options: 8-lead PDIP, 8-lead SOIC, 8-lead TSSOP

Descriptions:

• The AT24C16N is a low-power, high-reliability EEPROM designed for storing small amounts of non-volatile data.
• It supports I²C protocol for communication with microcontrollers and other devices.
• Features hardware write protection (via the WP pin) to prevent accidental data modification.
• Includes an internal address counter for sequential reads.

Features:

• Low Power Consumption:
• Active Read Current: 1 mA (typical)
• Standby Current: 6 µA (typical)
• Built-in Error Detection:
• Supports Acknowledge Polling to confirm write completion.
• Noise Immunity:
• Schmitt Trigger inputs for improved signal integrity.
• Industrial-Grade Reliability:
• High endurance and long data retention.
• RoHS Compliant:
• Lead-free and environmentally friendly.

The AT24C16N is commonly used in applications such as smart meters, automotive systems, industrial controls, and consumer electronics for storing configuration data, calibration settings, and other critical parameters.
