FT24C64A-ULR-T

Overview

The FT24C64A-ULR-T is a 64Kbit (8K x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 800 kHz and features a write cycle time of 5ms. The device operates within a supply voltage range of 1.8V to 5.5V and supports an access time of 700 ns. It is housed in a SOT-23-5 surface-mount package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Non-volatile memory storage utilizing EEPROM technology for data retention without power.
• Synchronous two-wire serial communication via standard I²C bus protocol.
• Wide operating voltage compatibility supporting low-power embedded systems.

Applications

• Data logging in battery-powered portable devices
• Configuration storage in consumer electronics
• Parameter retention in industrial control modules

Procurement Notes

Verify the specific suffix 'ULR-T' against official Fremont Micro Devices documentation to confirm the SOT-23-5 package and 800 kHz speed variant. Ensure the ordering code matches the required tape-and-reel quantity. Cross-reference datasheets to distinguish this model from similar FT24C64 variants with different pinouts or electrical characteristics.

Selection Notes

Select this component when a compact SOT-23-5 footprint is required for 64Kbit non-volatile storage. It is suitable for applications demanding I²C connectivity with moderate speed requirements up to 800 kHz. Consider the 1.8V minimum supply voltage for compatibility with low-voltage logic levels in modern embedded designs.

Part Context

This part belongs to the FT24C64A series of serial EEPROMs from Fremont Micro Devices. The series offers various packaging options including DIP and DFN, but the ULR-T specifically denotes the small outline transistor package variant. It serves as a cost-effective solution for storing calibration data or user settings in space-constrained electronic assemblies.

Replacement Considerations

FT24C64A-ENR-T: Offers identical electrical specifications but utilizes an 8-DFN package instead of SOT-23-5. Pinout compatibility must be verified before substitution due to physical form factor differences.
