FT24C04A-KSR-T

Overview

The FT24C04A-KSR-T is a 4Kb (512 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I2C compatible two-wire serial interface with a maximum clock frequency of 1 MHz and an access time of 550 ns. The device operates within a supply voltage range of 1.8V to 5.5V and supports page write cycles of 5 ms. It is housed in an 8-SOP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports hardware write protection for the upper half of the memory block
• Features a self-timed write cycle with automatic erase capabilities
• Includes a page-write buffer for efficient data handling

Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-power CMOS technology
• Automotive applications operating within extended temperature ranges

Procurement Notes

Verify the specific suffix 'KSR' against official Fremont Micro Devices documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with existing board layouts, as pin configurations may vary between SOP and other package options within the same series. Cross-reference with authorized distributors to confirm current availability status.

Selection Notes

Select this component when a 4Kb capacity is required alongside I2C interface compatibility. Consider the 1.8V to 5.5V operating range for versatile power supply integration. Evaluate the 1,000,000 erase/write cycle endurance and >200-year data retention for long-term reliability requirements in embedded systems.

Part Context

This part belongs to the FT24C04A/08A/16A series of serial Electrical Erasable and Programmable Read Only Memory devices. These components are organized as 512, 1024, or 2048 words of 8 bits each. The series leverages advanced CMOS technology to significantly reduce power consumption compared to older NMOS serial devices while maintaining standard two-wire bus compatibility.
