FT24C64A-ESR-B

Overview

The FT24C64A-ESR-B is a 65,536-bit serial EEPROM manufactured by Fremont Micro Devices Ltd. It features an I²C interface with a maximum clock frequency of 1 MHz and a write cycle time of 5 ms. The device operates within a supply voltage range of 1.8V to 5.5V and supports a wide operating temperature range from -40°C to +85°C. Packaged in an 8-SOP format, it provides non-volatile data storage organized as 8K x 8 bits.

Feature Summary

• Supports standard I²C serial communication protocol
• Provides non-volatile memory retention for stored data
• 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 'B' against the manufacturer's latest datasheet to confirm package dimensions and pinout compatibility. Ensure the I²C address configuration matches the target system requirements before integration. Cross-reference the 8-SOP physical footprint with the PCB design library to prevent assembly errors during manufacturing.

Selection Notes

Select this component when a compact 64Kbit EEPROM with I²C connectivity is required. It is suitable for applications needing reliable non-volatile storage within a small surface-mount package. Consider the 1.8V to 5.5V operating range for flexibility in various power supply environments.
