FT24C16A-UTR-B

Overview

The FT24C16A-UTR-B is a 16Kb (2048 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes a standard two-wire I2C bi-directional serial interface for data transfer. The device 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. It features a self-timed write cycle with a maximum duration of 5 ms and includes hardware write protection via the WP pin. The component is housed in an 8-TSSOP package and is rated for industrial operating temperatures ranging from -40°C to 85°C.

Feature Summary

• Supports 16-byte page write operations with partial page write capability.
• Includes Schmitt triggers and filtered inputs on all pins for enhanced noise immunity.
• Features automatic erase-before-write functionality during programming cycles.
• Provides hardware data protection through a dedicated Write Protect pin.

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 ordering suffix matches the required package type and environmental compliance standards. Confirm the RoHS status aligns with manufacturing regulations. Ensure the lead time accommodates production schedules as availability may fluctuate. Validate that the supplier provides original manufacturer documentation to guarantee authenticity.

Selection Notes

Select this component when a single device per bus is acceptable due to the lack of address pins. Consider the 16-byte page size for efficient sequential data writing. Verify that the system power supply remains stable within the 1.8V to 5.5V range to ensure reliable operation across the full temperature spectrum.

Part Context

This part belongs to the FT24C04A/08A/16A series of Two-Wire Serial EEPROMs. It shares architectural similarities with smaller capacity variants but lacks chip select address pins, limiting deployment to one unit per I2C bus segment. The 'U' indicates the industrial temperature grade, while 'T' specifies tape and reel packaging.

FAQ

Can multiple FT24C16A devices be connected to the same I2C bus?

No, the FT24C16A does not utilize device address pins (A0-A2 are NC). Consequently, only one FT24C16A device can be addressed on a single two-wire serial bus.

How does the Write Protect pin function?

Connecting the WP pin to VIL allows programming operations. Connecting it to VIH or VCC disables all programming functions, protecting the memory array from writes while still permitting read operations.
