Descriptions:

• The 24WC04P is a low-power, byte-alterable EEPROM designed for reliable non-volatile data storage.
• Supports I²C protocol with a clock frequency up to 400 kHz (Fast Mode).
• Features software write protection and page write capability (up to 16 bytes per page).
• Includes a built-in write-protect pin (WP) for hardware data protection.

Features:

• Low Power Consumption:
• Active Read Current: 1 mA (max)
• Standby Current: 1 μA (max)
• Built-in Error Detection:
• Acknowledge polling for write completion.
• Page Write Buffer:
• Allows faster sequential writes (16-byte page mode).
• Hardware Write Protection (WP Pin):
• Prevents accidental writes when pulled high.
• Wide Voltage Range:
• Compatible with 1.8V, 2.5V, 3.3V, and 5V systems.

This EEPROM is commonly used in applications requiring small, reliable, and low-power non-volatile memory, such as consumer electronics, industrial systems, and embedded devices.
