FT24C16A-USR-T

Overview

The FT24C16A-USR-T is a 16Kb (2048 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes a standard two-wire I2C interface with clock frequencies up to 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 industrial temperatures from -40°C to 85°C. It features a self-timed write cycle of 5ms maximum, hardware write protection via the WP pin, and 16-byte page write capability. The component is housed in an SOP-8 package.

Feature Summary

• Supports low voltage operation ranging from 1.8V to 5.5V with minimal standby current consumption.
• Includes a dedicated hardware write protect pin to secure data against unauthorized programming.
• Features Schmitt triggers and filtered inputs on all pins for enhanced noise immunity.
• Provides automatic erase-before-write functionality and high endurance cycles.

Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in sensor modules

Procurement Notes

Verify that the specific suffix 'USR' corresponds to the SOP-8 package and RoHS compliant tape and reel packaging as defined in the manufacturer's ordering guide. Confirm that the required operating temperature range aligns with the industrial specification limits provided in the datasheet before finalizing procurement orders.

Selection Notes

Select this component when a single device per bus architecture is acceptable, as the FT24C16A lacks address pins for multi-device selection. Ensure the design accommodates the 16-byte page boundary constraints during write operations to prevent data rollover errors within the memory array structure.

Part Context

This part belongs to the FT24C04A/08A/16A series of two-wire serial EEPROMs. It shares identical electrical characteristics and interface protocols with the 4Kb and 8Kb variants, differing primarily in internal memory organization and addressing requirements. The series is designed for low-power applications using advanced CMOS technology.

FAQ

How many devices can be connected to a single I2C bus?

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

What is the function of the WP pin?

The Write Protect (WP) pin disables all programming functions when connected to VIL or left unconnected, while connecting it to VIH or VCC enables write operations.
