FT24C512A-USG-T

Overview

The FT24C512A-USG-T is a 512K-bit (65,536 x 8) serial EEPROM manufactured by Fremont Micro Devices. It operates within a supply voltage range of 1.8V to 5.5V and supports clock frequencies up to 1 MHz at 2.5V-5.0V or 400 kHz at 1.8V. The device features a standard two-wire bi-directional serial interface with Schmitt trigger inputs for noise protection. It includes a write protect pin for hardware data protection and supports 128-byte page writes. Endurance is rated at 1,000,000 cycles with 100 years data retention across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Supports low voltage and low power operations with extended VCC range from 1.8V to 5.5V.
• Features a standard two-wire bi-directional serial interface compatible with I2C protocols.
• Includes a dedicated write protect pin for hardware-based data protection.
• Provides high reliability with one million write cycle endurance and long-term data retention.

Applications

• Industrial control systems requiring non-volatile storage
• Commercial electronic devices needing low-power memory
• Embedded systems utilizing microcontrollers with serial interfaces

Procurement Notes

Verify the specific package suffix matches the required footprint, as the USG designation corresponds to the SOP-8 package variant. Confirm that the ordering code aligns with the desired tape and reel packaging option if automated assembly is planned. Ensure the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the datasheet revision date to confirm electrical specifications have not changed since initial design.

Selection Notes

Select this component when a 512K-bit capacity is required in a compact surface-mount form factor. It is suitable for designs operating between 1.8V and 5.5V without level shifting. Consider the 128-byte page write capability for efficient data logging applications. Verify that the system bus speed does not exceed the maximum frequency supported at the minimum operating voltage.

Part Context

This part belongs to the FT24CxxxA series of two-wire serial EEPROMs from Fremont Micro Devices. The series offers various densities including 4K, 8K, and 16K options alongside the 512K variant. These devices share common interface protocols and physical pinouts, facilitating design scalability across different memory requirements while maintaining software compatibility.

Replacement Considerations

Compatible substitutes include the AT24C512C and CAT24C512C, which offer similar 512K-bit capacities and I2C interfaces. Verify pinout compatibility and voltage ranges before substitution. Ensure the alternative device supports the required page write size and industrial temperature range specifications.
