FT24C16A-USG-T

Overview

The FT24C16A-USG-T is a 16K-bit (2048 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes a standard two-wire I²C interface with a maximum clock frequency of 1 MHz at 5V and 400 kHz at lower voltages. The device operates within a supply voltage range of 1.8V to 5.5V and supports page write modes of up to 16 bytes. It features hardware data protection via a Write Protect pin, self-timed write cycles of 5ms maximum, and an industrial operating temperature range from -40°C to 85°C.

Feature Summary

• Supports low voltage and low power operations across a wide supply range.
• Includes hardware data protection through a dedicated Write Protect pin.
• Features Schmitt trigger inputs for enhanced noise immunity.
• Provides high reliability with significant endurance and long-term data retention.

Applications

• Data storage in battery-powered portable devices
• Configuration memory for embedded systems
• Parameter storage in industrial control equipment

Procurement Notes

Verify the package type matches the 'S' suffix for SOP-8 and the 'T' suffix for tape and reel packaging. Confirm the 'G' option indicates RoHS compliance. Ensure the ordering code corresponds to the specific temperature grade required for your application environment.

Selection Notes

Select this component when a single device per bus is acceptable, as address pins are not utilized. Consider the 16-byte page write capability for efficient data programming. Verify that the system voltage falls within the 1.8V to 5.5V operational range to ensure proper functionality.

Part Context

This part belongs to the FT24C04A/08A/16A series of Two-Wire Serial EEPROMs. It shares common interface protocols and electrical characteristics with the 4K and 8K variants but offers higher density. The series is designed for applications requiring non-volatile memory with low power consumption and robust noise protection.

Replacement Considerations

Compatible substitutes include other 16K-bit I²C EEPROMs from manufacturers such as ON Semiconductor (e.g., CAT24C16). Verify pin compatibility, voltage ranges, and interface timing specifications before substitution.

FAQ

How many FT24C16A devices can be connected on the same bus?

Only one FT24C16A device can be used on a single 2-wire bus because it does not utilize device address bits.

What is the function of the WP pin?

The Write Protect (WP) pin disables all programming functions when connected to VCC or VIH, protecting the EEPROM array from accidental writes while allowing read operations.
