Tổng quan
Description
Key features include:
1. Interface: It uses an I²C (Inter-Integrated Circuit) two-wire serial interface, compatible with fast-mode and fast-mode plus, supporting data transfer rates up to 1 MHz.
2. Operating Voltage: The device operates over a wide voltage range of 1.7V to 5.5V, making it versatile for various applications.
3. Data Retention and Endurance: It ensures data retention of 100 years and endurance of a million write cycles per byte.
4. Package: The 'SSHD' suffix indicates a small outline package, which is ideal for space-constrained applications.
5. Security Features: Optional software write protection and hardware write-protect pin enhance data security.
The AT24CM02-SSHD-B is ideal for applications necessitating high-reliability data storage with minimal space requirements.

Features
Pinout
Here is a concise description of its pin functions:
1. A0, A1, A2 (Pins 1, 2, 3): These are device address pins that allow up to eight devices to be connected on the same bus by configuring these pins.
2. GND (Pin 4): Ground pin for the device.
3. SDA (Pin 5): Serial Data line, used for both input and output. It is bi-directional.
4. SCL (Pin 6): Serial Clock line. This pin is used to synchronize data transfer.
5. WP (Pin 7): Write Protect pin. When connected to VCC, it prevents write operations to the entire memory.
6. VCC (Pin 8): Supply voltage pin for the device.
The AT24CM02 communicates via the I2C protocol, making it suitable for applications requiring serial data storage and retrieval.
