FT24C04A-KSR-B

Overview

The FT24C04A-KSR-B is a 4-Kbit serial EEPROM manufactured by Fremont Micro Devices Ltd. It features an I2C-compatible interface and is organized as 512 words by 8 bits. The device operates with a maximum clock frequency of 1 MHz and supports supply voltages down to 1.8 V. It utilizes a 5-pin SOT-23 package and functions within a temperature range of -40 °C to +85 °C.

Feature Summary

• Supports standard I2C bus communication protocols for data transfer.
• Provides non-volatile storage capability for persistent data retention.
• Designed for compact integration using a small surface-mount footprint.

Applications

• Consumer electronics requiring low-power configuration storage
• Industrial control systems needing parameter logging
• Automotive modules utilizing space-constrained memory solutions

Procurement Notes

Verify the manufacturer designation carefully, as Fremont Micro Devices has undergone corporate restructuring and asset transfers. Confirm that the specific suffix corresponds to the intended voltage and package variant. Ensure documentation aligns with current production status to avoid obsolete stock issues.

Selection Notes

Select this component when a 4-Kbit capacity is required in a minimal 5-pin form factor. It serves as a suitable alternative for designs needing 1.8 V operation and high-speed 1 MHz I2C access. Consider thermal limits if operating near the upper boundary of the specified range.

Part Context

This part belongs to the FT24CxxA series of serial EEPROMs from Fremont Micro Devices. These devices are engineered to replace legacy offerings in applications demanding reduced power consumption and smaller physical dimensions while maintaining compatibility with standard two-wire serial interfaces.
