FT24C16A-UTR-T

Overview

The FT24C16A-UTR-T is a 16Kb (2048 x 8) Two-Wire Serial EEPROM manufactured by Fremont Micro Devices Ltd. It 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. The device utilizes a standard I2C interface with Schmitt trigger inputs for noise protection. It features a self-timed write cycle of 5ms maximum, hardware write protection via the WP pin, and an industrial operating temperature range from -40°C to 85°C. The component is housed in an 8-pin TSSOP package.

Feature Summary

• Supports 16-byte page write mode with partial page write capability.
• Includes a dedicated Write Protect (WP) pin for hardware data protection.
• Features automatic erase before write operations.

Applications

• Low power embedded systems requiring non-volatile storage
• Industrial control devices operating in wide temperature ranges
• Consumer electronics utilizing I2C communication protocols

Procurement Notes

Verify that the ordering suffix 'UTR' corresponds to the specific TSSOP-8 package and tape-and-reel packaging configuration required for your assembly process. Confirm RoHS compliance status matches project specifications. Ensure the design accommodates the single-device limitation on the I2C bus due to the lack of address pins for this capacity variant.

Selection Notes

Select this part when a 16Kb memory density is required alongside low standby current consumption. The extended voltage range supports both 1.8V and 5V logic systems. Note that unlike smaller variants in the series, this model does not utilize chip select address pins, limiting bus topology to a single device per bus segment.

Part Context

This component belongs to the FT24C16A series of serial EEPROMs produced by Fremont Micro Devices Ltd. It shares architectural similarities with the FT24C04A and FT24C08A models but offers higher storage capacity. The series is designed for applications demanding high reliability and low power operation across industrial temperature conditions.

Replacement Considerations

Publicly confirmed substitute part numbers include FT24C16A-ETG-T, FT24C16A-UTG-B, FT24C16A-UTG-T, FT24C16A-UTR-B, and FT24C16A-UTR-T.

FAQ

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

No, the FT24C16A does not use device address pins (A0-A2 are no-connect). Consequently, only one FT24C16A device can be used on a single 2-wire bus.

How is data protected from accidental writing?

Data protection is managed via the Write Protect (WP) pin. Connecting WP to VCC disables all programming functions, while leaving it unconnected or connecting it to VIL allows write operations.
