FT93C46A-USR-T

Overview

The FT93C46A-USR-T is a non-volatile EEPROM memory IC manufactured by Fremont Micro Devices Ltd. It features a 1Kb storage capacity organized as 128 x 8 or 64 x 16 bits. The device utilizes a 3-wire serial interface with a clock frequency of 1 MHz. It operates within a supply voltage range of 1.8V to 5.5V and supports an industrial temperature range of -40°C to +85°C. The component is housed in an 8-SOP surface-mount package.

Feature Summary

• Non-volatile data retention capability for persistent storage
• Serial communication via a simplified 3-wire interface
• Wide operating voltage compatibility from low power to standard logic levels

Applications

• Embedded systems requiring small-scale parameter storage
• Industrial control devices needing configuration data retention
• Consumer electronics utilizing serial memory interfaces

Procurement Notes

Verify the specific suffix 'USR-T' against official Fremont Micro Devices documentation to confirm the tape-and-reel packaging format and exact electrical characteristics. Ensure the selected variant matches the required board space and thermal specifications for the target application environment.

Selection Notes

Select this component when a compact surface-mount EEPROM with low pin count is required. The 1MHz serial speed suits moderate data throughput needs. Confirm that the 1.8V minimum supply voltage aligns with the system's power rails, as some variants may have different voltage thresholds.

Part Context

This part belongs to the 93C46A series of serial EEPROMs. It provides a cost-effective solution for storing calibration data or user settings in space-constrained designs. The manufacturer offers various package options within this family to accommodate different assembly requirements.

Replacement Considerations
