FT24C16A-USG-B

Overview

The FT24C16A-USG-B is a 16Kbit serial EEPROM from Fremont Micro Devices Ltd, organized as 2048 words of 8 bits. It operates within a supply voltage range of 1.8V to 5.5V and supports clock frequencies up to 1 MHz at 5V or 400 kHz at lower voltages. The device utilizes a standard two-wire bi-directional serial interface with Schmitt trigger inputs for noise protection. It features a self-timed write cycle of 5ms maximum, hardware data protection via a write protect pin, and high reliability with 1,000,000 cycles endurance and 100 years data retention.

Feature Summary

• Supports low voltage and low power operations across an extended supply range.
• Includes a dedicated write protect pin for hardware-level data security.
• Features automatic erase before write operation and partial page write capability.

Applications

• Data logging in industrial control systems
• Configuration storage in embedded controllers
• Parameter memory in consumer electronics

Procurement Notes

Verify the specific package type and RoHS compliance status against the manufacturer's current documentation. Confirm that the ordering suffix corresponds to the required tube packaging variant. Ensure compatibility with the target system's voltage levels and I2C bus speed requirements before finalizing procurement.

Selection Notes

Select this component when a 16Kbit non-volatile memory solution is required with a single-device constraint on the I2C bus. The FT24C16A is suitable for applications needing hardware write protection and robust data retention. Consider the operating temperature range and supply voltage compatibility with the host microcontroller.

Part Context

This part belongs to the FT24C04A/08A/16A series of Two-Wire Serial EEPROMs manufactured by Fremont Micro Devices Ltd. The series offers varying memory densities (4K, 8K, and 16K bits) while maintaining consistent interface protocols and electrical characteristics. The USG suffix indicates a Green Package SOP-8 form factor with RoHS compliance.

FAQ

How many devices can be connected to the same I2C bus?

Only one FT24C16A device can be used on the same 2-wire bus because it does not utilize device address bits A2, A1, or A0.

What is the function of the WP pin?

The Write Protect (WP) pin protects the entire EEPROM array from programming. Programming is disabled when WP is connected to VCC or VIH.
