FT24C64A-ELR-T

Overview

The FT24C64A-ELR-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 1 MHz and features a write cycle time of 5 ms. The device operates within a supply voltage range of 1.8V to 5.5V and has an access time of 500 ns. It is housed in a SOT-23-5 surface-mount package and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports standard I²C serial communication protocol for data transfer.
• Provides non-volatile storage capability retaining data without power.
• Operates across a wide industrial temperature range.

Applications

• Data logging systems requiring persistent storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in sensor modules

Procurement Notes

Verify the specific suffix ELR-T confirms the SOT-23-5 package variant, as other suffixes may indicate different packages like DFN or TSSOP. Ensure compatibility with the target system's I²C bus voltage levels, given the 1.8V to 5.5V operating range. Confirm RoHS3 compliance requirements if applicable to the final assembly standards.

Selection Notes

Select this component when a small form factor is required due to the SOT-23-5 footprint. It is suitable for applications needing moderate capacity (64Kbit) with fast access times. Consider the 1 MHz I²C speed for bandwidth requirements. Verify that the 5ms write cycle time aligns with the application's timing constraints.

Part Context

This part belongs to the FT24C64A series from Fremont Micro Devices, which offers various pinout and package options for the same memory core. The ELR-T designation specifically identifies the SOT-23-5 package version. Other variants in the family include ENR-T (8-DFN) and ETR-T counterparts with different capacities but similar interfaces.

Replacement Considerations

Direct substitutes include other 64Kbit I²C EEPROMs in SOT-23-5 packages from manufacturers such as Microchip (24AA64E48) or STMicroelectronics (24LC64B), provided pinouts and voltage ranges are compatible.
