Overview

The AT24C16D-SSHM-T is a 16-Kbit non-volatile I2C EEPROM organized as 2,048 bytes of 8 bits each. It operates over a wide voltage range of 1.7V to 3.6V and supports clock frequencies up to 1 MHz. This component features integrated Schmitt triggers and noise suppression filters on inputs to ensure reliable data integrity in noisy embedded environments.

Why Choose This Part

This EEPROM offers extremely low power consumption, drawing only 0.8 uA in standby mode and a maximum of 0.5 mA during active read/write cycles at 1 MHz. It provides high reliability with 100-year data retention and includes a hardware write-protect pin to safeguard the entire memory array against accidental data corruption.

Applications

Configuration Storage
Ideal for storing calibration data, user settings, and device configuration parameters in space-constrained embedded systems.
Event Logging
Used to record system fault logs, usage statistics, or sensor data history with a high endurance of 1,000,000 write cycles.
Device Identification
Commonly employed for storing serial numbers, MAC addresses, and revision information for hardware identification.

Getting Started

To interface with this device, connect the SDA and SCL lines to a microcontroller I2C bus with external pull-up resistors. Ensure the WP pin is tied to GND for normal write operations or VCC for hardware protection. Microchip provides the AVR-IoT or SAM-series development boards that can be used to evaluate these memory devices using standard I2C libraries.
