The 24WC16J is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Catalyst Semiconductor (CSI). Below are its factual specifications, descriptions, and features:

Specifications:

• Memory Size: 16 Kbit (2 Kbyte)
• Organization: 2048 x 8 bits
• Interface: I²C (2-wire serial interface)
• Supply Voltage: 1.8V to 5.5V (wide operating range)
• Operating Temperature Range: -40°C to +85°C
• Write Cycle Endurance: 1,000,000 cycles (minimum)
• Data Retention: 100 years (minimum)
• Page Write Buffer: 16 bytes
• Clock Frequency: Up to 400 kHz (I²C Fast Mode)
• Package Type: 8-pin SOIC, PDIP, or TSSOP

Descriptions:

• The 24WC16J is a non-volatile memory device designed for low-power applications.
• It supports sequential read operations for faster data access.
• Features write protection via a hardware write-protect pin (WP).
• Compatible with I²C protocol and supports standard (100 kHz) and fast (400 kHz) modes.

Features:

• Low Power Consumption:
• Active Read Current: 1 mA (typical)
• Standby Current: 1 µA (typical)
• Built-in Error Detection:
• Acknowledge polling for write completion.
• Hardware Write Protection:
• Prevents accidental writes when WP pin is held high.
• Industrial-Grade Reliability:
• High endurance and long data retention.

This EEPROM is commonly used in consumer electronics, industrial systems, and embedded applications requiring reliable non-volatile memory storage.
