Description
The AT24C02C-SSHM-B is a 2-kilobit (256 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) produced by Microchip Technology. It is part of the AT24C series and is designed for low-power, non-volatile data storage. The device operates with an I2C (Inter-Integrated Circuit) two-wire serial interface, allowing it to communicate with microcontrollers and other devices using only two signal lines, plus ground.
Key features include a wide operating voltage range (1.7V to 5.5V), low power consumption, and a standard 8-pin SOIC (Small Outline Integrated Circuit) package. It offers byte-level and page-level writing capabilities, with a page size of 8 bytes. The EEPROM is highly reliable, with over 1 million write cycles and data retention of up to 100 years. The AT24C02C-SSHM-B is typically used in applications such as data logging, configuration settings, and device identification. It supports a maximum clock frequency of 1 MHz and is suitable for use in consumer electronics, industrial, and automotive applications.

Pinout
The AT24C02C-SSHM-B is an EEPROM (Electrically Erasable Programmable Read-Only Memory) device with an 8-pin configuration. Here is a brief overview of its pin functions:
1. A0, A1, A2 (Pins 1, 2, 3): These are address pins used to set the device address, allowing up to eight devices on the same I2C bus by configuring these pins differently.
2. GND (Pin 4): This is the ground pin and should be connected to the system ground.
3. SDA (Pin 5): The Serial Data line is used for data input and output. It is a bidirectional pin used to transfer data to and from the device.
4. SCL (Pin 6): The Serial Clock line is used to synchronize the data transfer between the microcontroller and the EEPROM.
5. WP (Pin 7): The Write Protect pin is used to enable or disable write protection to the entire memory array. When connected to VCC, write protection is enabled.
6. VCC (Pin 8): This pin is the power supply pin for the device, typically connected to a supply voltage of 1.7V to 5.5V.
These pins work together to facilitate communication over the I2C protocol, allowing the microcontroller to read from and write to the memory.
