Overview

The AT24C04D-STUM-T is a 4Kbit serial EEPROM organized as 512 bytes of 8 bits each, designed for low-power and low-voltage applications. It features a high-speed I2C interface supporting clock frequencies up to 1 MHz and operates within a voltage range of 1.7V to 3.6V. This component is housed in a compact 5-lead SOT-23 package, making it suitable for space-constrained designs requiring non-volatile data storage.

Why Choose This Part

The device offers a very low standby current of approximately 0.8 uA and features Schmitt triggers on inputs for enhanced noise suppression. It supports a 16-byte page write mode and a self-timed write cycle of maximum 5ms, ensuring efficient data handling and high reliability.

Applications

Configuration Storage
Storing calibration data, user settings, and device configuration parameters in consumer and industrial electronics.
Asset Tracking
Maintaining serial numbers, MAC addresses, and revision history in compact IoT modules.
Event Logging
Recording error codes or operational logs in low-power handheld devices.

Getting Started

To interface with this EEPROM, connect the SDA and SCL lines to an I2C-capable microcontroller with appropriate pull-up resistors. Use the WP pin to provide hardware data protection for the entire memory array when tied high. Software implementation can follow standard I2C bidirectional protocols for random or sequential read and write operations.
