FT24C512A-UTR-B

Overview

The FT24C512A-UTR-B is a 512K-bit (65,536 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It operates within a supply voltage range of 1.8V to 5.5V and supports clock frequencies up to 1 MHz at 2.5V–5.5V or 400 kHz at 1.8V. The device features a standard two-wire I2C interface, 128-byte page write capability, and hardware write protection via the WP pin. It includes Schmitt trigger inputs for noise filtering and automatic erase-before-write functionality.

Feature Summary

• Supports 128-byte page writes with partial page write operations allowed.
• Includes a dedicated Write Protect (WP) pin for hardware data protection.
• Features internally organized memory with automatic erase before write cycles.
• Equipped with Schmitt triggers and filtered inputs for enhanced noise immunity.

Applications

• Data logging in industrial environments
• Configuration storage for embedded systems
• Parameter retention in low-power devices

Procurement Notes

Verify that the ordering suffix 'B' corresponds to tube packaging as per the official datasheet table. Confirm the specific package type required (e.g., DIP, SOP, MSOP, TSSOP, or UDFN) matches the middle character in the part number structure. Ensure the voltage and temperature specifications align with system requirements before procurement.

Selection Notes

Select this component when high-density non-volatile storage is needed with a standard I2C interface. It is suitable for applications requiring wide voltage operation from 1.8V to 5.5V. Consider the 128-byte page write mode for efficient data programming. Verify that the available package types meet the PCB layout constraints.

Part Context

This part belongs to the FT24CxxxA series of Two-Wire Serial EEPROMs from Fremont Micro Devices. The series offers various densities including 2K, 4K, 8K, 16K, 32K, 64K, 128K, 256K, and 512K bits. All members share similar I2C compatibility and low-power CMOS fabrication processes.

FAQ

How does the Write Protect (WP) pin function?

When the WP pin is connected to VCC or VIH, all programming functions are disabled. Read operations remain unaffected regardless of the WP pin state.

What is the maximum write cycle time?

The self-timed write cycle has a maximum duration of 5 ms.
