FT24C04A-UTG-T

Overview

The FT24C04A-UTG-T is a 4K-bit (512 x 8) serial EEPROM from Fremont Micro Devices Ltd, utilizing an I²C interface. 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 features a maximum standby current of less than 1µA and includes hardware write protection via the WP pin. It is housed in an 8-pin TSSOP package with industrial temperature ratings.

Feature Summary

• Supports 16-byte page write operations with partial page write capability.
• Includes Schmitt trigger inputs for noise filtering and automatic erase before write.
• Features hardware data protection through a dedicated Write Protect pin.

Applications

• Low power consumer electronics requiring non-volatile storage
• Industrial control systems operating in wide voltage environments
• Data logging applications needing high endurance memory

Procurement Notes

Verify that the specific ordering suffix matches the required package type and environmental compliance standards. Confirm the manufacturer's datasheet revision aligns with your design specifications. Ensure compatibility with the target system's I²C bus timing requirements and voltage levels before finalizing procurement decisions.

Selection Notes

Select this component when a 4K-bit capacity is sufficient for the application. Consider the TSSOP package if space constraints require a surface-mount solution. Evaluate the need for hardware write protection and the specific voltage requirements of the host system against the device's 1.8V to 5.5V operating range.

Part Context

This part belongs to the FT24C04A/08A/16A series of two-wire serial EEPROMs. The 'U' indicates an industrial temperature range, 'T' denotes tape and reel packaging, 'G' signifies a green RoHS-compliant package, and 'S' identifies the SOP/TSSOP family. It shares core architecture with other capacities in the series but differs in address pin configurations.

FAQ

How many devices can be connected on the same I²C bus?

Up to four FT24C04A devices can be wired-OR on the same bus using the A2 and A1 address pins.

What is the function of the WP pin?

The WP pin provides hardware write protection; connecting it to VCC disables all programming functions while leaving read operations unaffected.
