FT24C04A-EDR-B

Overview

The FT24C04A-EDR-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 a maximum clock frequency of 1 MHz at 5V and 400 kHz at lower voltages. The device operates on a supply voltage range of 1.8V to 5.5V, supports 16-byte page writes, and includes hardware write protection via the WP pin. It offers high endurance of one million write cycles and data retention exceeding 100 years.

Feature Summary

• Supports standard two-wire bi-directional serial communication compatible with I²C bus protocols.
• Includes a dedicated Write Protect (WP) pin for hardware-level data protection against unauthorized programming.
• 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 memory solutions
• IoT devices needing reliable parameter retention

Procurement Notes

Verify the specific package type associated with the EDR suffix against official ordering tables. Confirm RoHS compliance status and ensure the supplier provides valid datasheets matching the DS3001M revision. Check for availability constraints as distribution channels may vary.

Selection Notes

Select this component when a 4K-bit capacity is required within a compact footprint. Ensure the design accommodates the 1.8V to 5.5V operating range and utilizes the WP pin if permanent data locking is necessary. Verify that the system bus speed does not exceed the specified limits for the target supply voltage.
