FT24C04A-ETG-B

Overview

The FT24C04A-ETG-B is a 4K-bit (512 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It features an I2C-compatible two-wire interface with clock frequencies up to 1 MHz at 5V and 400 kHz at lower voltages. Operating within a supply voltage range of 1.8V to 5.5V, it supports page writes of up to 16 bytes and includes hardware write protection via the WP pin. The device is housed in an 8-pin TSSOP package and operates across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports standard two-wire bi-directional serial communication with Schmitt trigger inputs for noise immunity.
• Includes a dedicated Write Protect (WP) pin to prevent accidental programming of the memory array.
• Features self-timed internal erase and write cycles that automatically disable external inputs during operation.

Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-power microcontrollers
• Automotive embedded applications operating in harsh environments

Procurement Notes

Verify the specific ordering suffix 'B' corresponds to tube packaging as defined in the manufacturer's order code table. Confirm RoHS compliance status matches project requirements. Ensure the selected package variant aligns with PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this component when a 4K-bit capacity is required alongside robust hardware write protection. The wide voltage range accommodates various logic levels without level shifting. Verify that the system bus speed does not exceed the specified limits for the target supply voltage to ensure reliable data transfer.
