Overview

The AT24C64D-XHM-T is a 64Kbit serial EEPROM organized as 8,192 bytes of 8 bits each. It operates over a wide voltage range of 1.7V to 5.5V and utilizes an I2C-compatible interface capable of speeds up to 1 MHz. This non-volatile memory is designed for industrial applications requiring high endurance and reliable data retention.

Why Choose This Part

This device features noise suppression through Schmitt triggers and filtered inputs, ensuring robust performance in electrically noisy environments. It offers exceptional reliability with 1,000,000 write cycles and 100-year data retention, alongside a hardware write-protect pin for superior data security.

Applications

System Configuration Storage
Storing calibration data, user settings, and network configuration parameters in industrial equipment.
Boot Code Storage
Holding small bootloader routines or look-up tables for microcontrollers with limited internal non-volatile memory.
Event Logging
Recording error codes, usage statistics, and timestamped events in battery-powered devices due to low standby current.
Asset Tracking
Storing serial numbers and maintenance history in modular hardware components.

Getting Started

Connect the SCL and SDA pins to your microcontroller's I2C bus with appropriate pull-up resistors, typically 2.2k to 10k ohms. Use the A0, A1, and A2 pins to set the hardware address for up to eight devices on a single bus. Ensure the WP pin is tied to GND for normal write operations or VCC to protect the memory array.
