Description

The AT24CM02-SSHD-T is a 2-kilobit (256 x 8 bits) EEPROM (Electrically Erasable Programmable Read-Only Memory) device from Atmel (now part of Microchip Technology). It features a two-wire I²C interface for communication, enabling easy integration with microcontrollers and other digital devices.
Key features include:
- Memory Size: 2 Kbit organized as 256 bytes.
- Interface: I²C with standard, fast, and high-speed modes.
- Voltage Range: Operates typically from 1.7V to 5.5V, allowing for low-power applications.
- Data Retention: Offers a data retention period of over 100 years.
- Endurance: Supports up to 1 million write/erase cycles.
The "SSHD" in the name indicates it’s a small, surface-mount package, making it suitable for compact designs. Its low power consumption and reliable performance make it ideal for applications such as consumer electronics, industrial devices, and automotive systems where non-volatile memory is essential.
