FT24C04A-ULR-T

Overview

The FT24C04A-ULR-T is a 4K-bit (512 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I2C interface with a maximum clock frequency of 1 MHz at 5V and 400 kHz at lower voltages. The device operates within a supply voltage range of 1.8V to 5.5V and supports industrial temperatures from -40°C to 85°C. It features a 16-byte page write mode, hardware write protection via the WP pin, and low standby current. The component is housed in a 5-pin SOT-23 package.

Feature Summary

• Supports standard two-wire bi-directional serial communication compatible with I2C bus modes.
• Includes a dedicated Write Protect (WP) pin for hardware-level data protection against unauthorized programming.
• Features self-timed internal write cycles that automatically erase memory before writing.

Applications

• Low power embedded systems requiring non-volatile data storage
• Industrial control units operating in wide temperature ranges
• Consumer electronics utilizing compact surface-mount packaging

Procurement Notes

Verify the specific ordering suffix 'L' corresponds to the SOT-23-5 package configuration required for your design. Confirm RoHS compliance status matches project specifications. Ensure the selected variant aligns with the intended PCB footprint and assembly process requirements.

Selection Notes

Select this component when a small 5-pin form factor is necessary for space-constrained designs. It serves as a direct alternative to larger 8-pin packages while maintaining identical electrical performance and memory organization. Verify compatibility with existing I2C bus addressing schemes using the A2 and A1 pins.

Part Context

This part belongs to the FT24C04A/08A/16A series of Two-Wire Serial EEPROMs. The series offers varying memory densities (4K, 8K, and 16K bits) but shares common interface protocols and operational characteristics. The FT24C04A specifically provides 4Kbit capacity organized into 512 words.
