FT24C04A-ETR-T

Overview

The FT24C04A-ETR-T is a 4K-bit (512 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It operates on a supply voltage range of 1.8V to 5.5V and supports I²C bus interfaces with clock frequencies up to 1 MHz at 5V and 400 kHz at lower voltages. The device features a self-timed write cycle of 5ms maximum, low standby current under 1µA, and an industrial operating temperature range from -40°C to 85°C. It utilizes an 8-pin TSSOP package.

Feature Summary

• Supports standard two-wire bi-directional serial interface for addressing read and write functions
• Includes hardware write protect pin to prevent programming operations when connected to high logic level
• Features automatic erase before write operation and partial page write capability within 16-byte pages

Applications

• Low power consumer electronics requiring non-volatile data storage
• Industrial control systems needing reliable parameter retention across wide temperature ranges
• Embedded microcontroller applications utilizing I2C communication protocols

Procurement Notes

Verify the specific ordering suffix 'ETR' corresponds to the 8-pin TSSOP package and tape and reel packaging format. Confirm RoHS compliance status matches project requirements. Ensure the manufacturer part number aligns exactly with the requested component specifications before finalizing procurement orders.

Selection Notes

Select this component for designs requiring small footprint surface mount integration with established I2C compatibility. Consider the 1.8V minimum operating voltage for battery-powered or low-voltage logic systems. Evaluate the 5ms write cycle time against application timing constraints during data logging or configuration updates.

FAQ

How many FT24C04A devices can be wired-OR on the same bus?

Four FT24C04A devices can be wired-OR on the same 2-wire bus using the A2 and A1 chip select address pins.

What is the function of the WP pin?

The Write Protect (WP) pin protects the entire EEPROM array from programming. Programming is disabled if WP is connected to VCC or VIH.
