FT24C04A-ESR-T

Overview

The FT24C04A-ESR-T is a 4K-bit (512 x 8) serial EEPROM from 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 on a single supply voltage of 1.8V to 5.5V, it supports 16-byte page writes and includes hardware write protection via the WP pin. The device operates within an industrial temperature range of -40°C to +85°C.

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 Schmitt trigger inputs with noise filtering to ensure signal integrity in electrically noisy environments.

Applications

• Non-volatile data storage in industrial control systems
• Configuration memory for embedded microcontroller applications
• Parameter logging in battery-powered low-power devices

Procurement Notes

Verify that the specific suffix 'ESR' corresponds to the required package type and tape-and-reel packaging configuration as defined in the manufacturer's ordering code table. Confirm RoHS compliance status and check for any recent Product Change Notifications (PCN) regarding lead finish or material composition updates before finalizing procurement.

Selection Notes

Select this component when a 4K-bit capacity is required alongside a compact footprint and robust noise immunity. Ensure the design accommodates the 1.8V minimum operating voltage if used in low-power scenarios. Verify that the system bus speed does not exceed the specified limits for the chosen supply voltage level.
