Overview

The AT24C04D-XHM-T is a 4Kbit non-volatile serial EEPROM utilizing an I2C (Two-Wire) interface capable of speeds up to 1 MHz. It is designed for low-power operation, drawing only 0.15mA during reads at 1 MHz and a standby current of 0.8uA. This device is housed in a space-saving 8-TSSOP package and operates across a wide voltage range of 1.7V to 3.6V.

Why Choose This Part

The component offers extremely low power consumption with a standby current under 1uA, making it ideal for battery-operated devices. Its support for 1 MHz Fast Mode Plus I2C ensures rapid data access, while the wide 1.7V to 3.6V supply range provides compatibility with modern low-voltage microcontrollers.

Applications

Parameter Storage
Storing calibration data, user preferences, and configuration settings in consumer and industrial electronics.
Device Identification
Retaining serial numbers, MAC addresses, and revision data for system identification and asset tracking.
Lookup Tables
Storing small constant data tables such as temperature compensation coefficients or LED characterization data.
State Preservation
Recording critical system state or error logs to ensure recovery after power cycles.

Getting Started

To interface with the AT24C04D, connect the SDA and SCL lines to your microcontroller's I2C peripheral with appropriate pull-up resistors. Ensure the WP (Write Protect) pin is tied to GND for standard write operations or to VCC to protect the memory array. Microchip's MCC (MHC) or standard I2C libraries for AVR, SAM, or PIC microcontrollers can be used to perform page and byte writes.
