FT24C512A-UTR-T

Overview

The FT24C512A-UTR-T is a 512K-bit (65,536 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes a standard two-wire I2C interface with clock frequencies up to 1 MHz at 2.5V–5.5V and 400 kHz at 1.8V. The device operates within a supply voltage range of 1.8V to 5.5V and supports an industrial temperature range of -40°C to 85°C. Key electrical parameters include a maximum write cycle time of 5 ms, read access times of 0.9 µs at 1.8V and 0.55 µs at 2.5V–5.0V, and typical endurance of 1,000,000 write cycles. It features 128-byte page write capability and hardware write protection via the WP pin.

Feature Summary

• Supports 128-byte page write operations with partial page write functionality.
• Includes a dedicated Write Protect (WP) pin for hardware-level data protection.
• Features Schmitt trigger inputs with noise filtering for signal integrity.
• Provides automatic erase-before-write capabilities during programming.

Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-voltage power supplies
• Embedded devices needing hardware-based write protection

Procurement Notes

Verify the specific package type against the ordering code suffix, as the 'U' designation corresponds to UDFN packaging in the official datasheet. Confirm that the required tape and reel quantity matches the manufacturer's standard packaging specifications. Ensure the design accommodates the specified voltage slew rates during power-up sequences to maintain device reliability.

Selection Notes

Select this component when a high-density 512K-bit EEPROM is required with a compact surface-mount footprint. The wide supply voltage range allows compatibility with both 1.8V and 5V logic systems. Consider the 128-byte page size for efficient bulk data writing compared to byte-only write alternatives.

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 clock frequency supported?

The device supports a maximum clock frequency of 1 MHz when operating between 2.5V and 5.5V, and 400 kHz when operating at 1.8V.
