FT24C16A-USR-B

Overview

The FT24C16A-USR-B is a 16Kbit (2048 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes a standard two-wire I2C interface for data transfer, supporting 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 features a self-timed write cycle with a maximum duration of 5ms. It is housed in an 8-pin SOP package and supports industrial temperature ranges from -40°C to 85°C.

Feature Summary

• Supports 16-byte page write mode with partial page write capability.
• Includes hardware write protection via the WP pin to prevent accidental programming.
• Features Schmitt trigger inputs and noise filtering for signal integrity.
• Provides automatic erase-before-write functionality during programming operations.

Applications

• Data storage in low-power embedded systems
• Configuration parameter retention in microcontroller circuits
• Calibration data logging in industrial sensors

Procurement Notes

Verify that the specific ordering suffix matches the required package type and compliance standards. Confirm RoHS status and packaging format against project specifications. Ensure compatibility with existing PCB footprints and assembly processes before finalizing procurement orders.

Selection Notes

Select this component when a 16Kbit non-volatile memory solution is required with I2C connectivity. Consider the 1.8V to 5.5V operating range for versatile power supply integration. Evaluate the 8-pin SOP package dimensions for mechanical fit within the target enclosure or board layout constraints.
