The AT24C02C-XHM-T is a 2K-bit (256 x 8) serial EEPROM manufactured by Atmel (now part of Microchip Technology). Below are its key specifications, descriptions, and features:

Specifications:

• Memory Size: 2K-bit (256 bytes)
• Interface: I²C-compatible (2-wire serial interface)
• Operating Voltage: 1.7V to 5.5V
• Write Cycle Time: 5ms (maximum)
• Endurance: 1,000,000 write cycles
• Data Retention: 100 years
• Operating Temperature Range: -40°C to +85°C
• Package: 8-pin TSSOP (XHM)

Descriptions:

• The AT24C02C is a low-power, byte-addressable EEPROM with a built-in write-protect feature.
• It supports sequential read operations for faster data access.
• The device includes a page write buffer (up to 8 bytes per write cycle).
• It is I²C-compatible, supporting clock frequencies up to 400kHz (Fast Mode) and 1MHz (Fast Mode Plus).

Features:

• Low Power Consumption: Active read current (1mA @ 5.5V), standby current (6µA @ 5.5V).
• Hardware Write Protection: WP pin enables/disables write operations.
• Internal Organization: 256 x 8 (2K bits).
• Extended Voltage Range: Operates from 1.7V to 5.5V.
• Industrial Temperature Range: -40°C to +85°C.
• Schmitt Trigger Inputs: Noise suppression on SCL and SDA lines.
• Automotive Grade Options: Available for automotive applications (AEC-Q100 qualified variants).

This EEPROM is commonly used in consumer electronics, industrial systems, automotive applications, and IoT devices for non-volatile data storage.
