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

Specifications:

• Memory Size: 2Kbit (256 x 8)
• Interface: I²C (Two-wire serial interface)
• Supply Voltage (VCC): 1.7V to 5.5V
• Operating Temperature Range: -40°C to +85°C
• Write Cycle Time: 5ms (max)
• Write Endurance: 1,000,000 cycles
• Data Retention: 100 years
• Package: 8-lead PDIP

Descriptions:

• The AT24C02C-PUM is a low-power, byte-addressable EEPROM with a 2Kbit capacity.
• It supports a standard I²C interface with clock frequencies up to 400kHz (Fast Mode) and 1MHz (Fast Mode Plus).
• Features a 16-byte page write buffer for efficient data storage.
• Includes a write protect pin (WP) to prevent accidental writes.

Features:

• Low Power Consumption:
• Active Read Current: 1mA (max)
• Standby Current: 6μA (max)
• Hardware Write Protection (WP Pin):
• When pulled HIGH, prevents writes to the memory array.
• Schmitt Trigger Inputs:
• Improves noise immunity.
• Self-Timed Write Cycle:
• No external timing required for write operations.
• Extended Voltage Range:
• Supports operation from 1.7V to 5.5V, making it suitable for battery-powered applications.

This EEPROM is commonly used in applications requiring non-volatile memory, such as consumer electronics, industrial systems, and automotive modules.
