FT24C512A-ETG-T

Overview

The FT24C512A-ETG-T is a 512Kbit (65,536 x 8) Two-Wire Serial EEPROM manufactured by Fremont Micro Devices Ltd. It operates within a supply voltage range of 1.8V to 5.5V and supports an I²C interface with a maximum clock frequency of 1 MHz. The device features a 128-byte page write mode with partial page write capability. Key electrical parameters include a 900 ns access time and a 5 ms write cycle time for both word and page operations. It is housed in an 8-TSSOP package and functions across a temperature range of -40°C to 85°C.

Feature Summary

• Supports low voltage and low power operations suitable for battery-powered applications
• Enables efficient data storage through 128-byte page write mode with partial page write functionality
• Provides non-volatile memory retention without requiring continuous power

Applications

• Low-power embedded designs requiring persistent data storage
• I²C-based system configuration and parameter logging
• Consumer electronics utilizing serial EEPROM for firmware or calibration data

Procurement Notes

Verify the specific suffix ETG-T against official Fremont Micro Devices documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with your target I²C bus voltage levels, as the device supports a wide range from 1.8V to 5.5V. Cross-reference the part number with authorized distributors to confirm current availability status, as stock levels may vary.

Selection Notes

Select this component when a 512Kbit capacity is required in an 8-pin surface-mount package. It is appropriate for systems needing fast access times and support for page writes to improve efficiency. Consider the operating voltage range to ensure it matches the system's power supply rails. Verify that the I²C address configuration meets the design requirements for multiple devices on the same bus.

Part Context

This part belongs to the FT24CxA series of Two-Wire Serial EEPROMs from Fremont Micro Devices. The series offers various capacities ranging from small bit counts up to 512Kbit, all sharing similar I²C interface characteristics. The FT24C512A represents the higher capacity option within this family, providing substantial non-volatile storage in a compact form factor suitable for space-constrained electronic designs.

Replacement Considerations

FT24C512A-ETR is listed as a parametric equivalent substitute.
