FT24C16A-UTG-B

Overview

The FT24C16A-UTG-B is a 16Kb (2048 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes a standard two-wire I2C interface and operates within a supply voltage range of 1.8V to 5.5V. The device supports clock frequencies up to 1 MHz at 5V and 400 kHz at lower voltages, with an access time of 550 ns. It features a self-timed write cycle of 5 ms maximum and includes hardware write protection via the WP pin. Packaged in an 8-TSSOP tube, it functions reliably across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Supports 16-byte page write operations with partial page write capability.
• Includes Schmitt trigger inputs for noise protection on SDA and SCL lines.
• Features a dedicated Write Protect (WP) pin for hardware data security.
• Provides automatic erase before write functionality during programming 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 ordering suffix 'B' corresponds to the Tube packaging format as specified in the manufacturer's order code table. Confirm the 'U' designation indicates the -40°C to 85°C industrial temperature range. Ensure the 'T' package type matches the required 8-TSSOP footprint. Cross-reference the RoHS compliance status if environmental regulations apply to your specific deployment environment.

Selection Notes

Select this component when a single device per bus is acceptable, as the FT24C16A does not utilize address pins A0-A2. It is suitable for applications needing 16Kb capacity without the complexity of multi-device addressing found in smaller variants like the FT24C04A or FT24C08A. Consider the 1.8V minimum operating voltage for low-power designs.

Part Context

This part belongs to the FT24C04A/08A/16A series of Two-Wire Serial EEPROMs from Fremont Micro Devices. The series shares common electrical characteristics and interface protocols but differs in memory organization and address pin usage. The FT24C16A variant specifically organizes memory as 2048 words of 8 bits, distinguishing it from the 4K and 8K bit densities of its siblings.

FAQ

How many FT24C16A devices can be connected to a single I2C bus?

Only one FT24C16A device can be used on a single 2-wire bus because all device address pins (A0, A1, and A2) are no-connects and do not allow for unique chip selection.

What is the function of the WP pin?

The Write Protect (WP) pin disables all programming functions when connected to VIH or VCC. Programming is allowed only when the pin is left unconnected or input to VIL.
