FT93C56A-ITR-T

Overview

The FT93C56A-ITR-T is a non-volatile EEPROM memory IC manufactured by Fremont Micro Devices Ltd. It offers a storage capacity of 2Kbit, organized as 256 x 8 or 128 x 16 bits. The device utilizes a 3-wire serial interface with a maximum clock frequency of 2 MHz. It operates within a supply voltage range of 1.8V to 5.5V and supports an industrial temperature range from -40°C to +85°C. The component is housed in an 8-TSSOP surface-mount package.

Feature Summary

• Provides 2Kbit non-volatile data retention for persistent storage applications
• Supports high-speed 3-wire serial communication up to 2 MHz
• Operates across a wide voltage range from 1.8V to 5.5V
• Designed for industrial temperature environments ranging from -40°C to +85°C

Applications

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

Procurement Notes

Verify the specific suffix 'ITR-T' to confirm the tape-and-reel packaging format and industrial temperature grade. Ensure compatibility with existing 3-wire serial protocols. Confirm that the 1.8V minimum operating voltage aligns with the target system's power rails. Check current availability status as distribution may vary.

Selection Notes

Select this component when a 2Kbit capacity is required rather than the 1Kbit variant. The 2 MHz clock speed offers faster throughput compared to 1 MHz alternatives. The TSSOP package is suitable for automated surface-mount assembly processes. Verify that the 3-wire interface matches the microcontroller's available pins.

Part Context

This part belongs to the FT93C56A series, which is functionally compatible with the industry-standard 93C56 architecture. It serves as a direct replacement for legacy EEPROMs in designs requiring 2Kbit storage. The manufacturer provides EDA models and datasheets to facilitate integration into schematic and layout workflows.

Replacement Considerations

FT93C56A-UTR-B is listed as a direct substitute offering identical electrical specifications but in tube packaging instead of tape-and-reel.
