FT93C56A-IDR-B

Overview

The FT93C56A-IDR-B is a non-volatile EEPROM memory IC manufactured by Fremont Micro Devices Ltd. It offers a storage capacity of 2Kb, 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 of -40°C to +85°C. The component is housed in an 8-DIP package (0.300 inch width) designed for through-hole mounting.

Feature Summary

• Non-volatile data retention capability
• Serial 3-Wire interface compatibility
• Wide operating voltage support

Applications

• Industrial control systems
• Consumer electronics configuration storage
• Automotive embedded applications

Procurement Notes

Verify the specific suffix 'IDR-B' corresponds to the 8-DIP through-hole package variant. Confirm that the 3-Wire interface requirement matches the target circuit design, as some variants may differ. Ensure the 1.8V to 5.5V supply range aligns with system power rails. Check current availability status as distribution channels may vary.

Selection Notes

Select this component when a through-hole DIP package is required for prototyping or legacy board designs. The 2Kb capacity suits small data storage needs like calibration values. The 3-Wire interface reduces pin count compared to SPI alternatives. Verify thermal requirements against the -40°C to +85°C industrial rating.

Part Context

This part belongs to the FT93C56A series of serial EEPROMs from Fremont Micro Devices Ltd. It is functionally compatible with standard 93C56 devices but includes enhanced features such as wide voltage operation. The series provides reliable non-volatile storage solutions for embedded systems requiring simple serial communication protocols.

Replacement Considerations

FT93C56A-ITR-B: Surface mount TSSOP version of the same electrical specification. AT93C56D: Compatible alternative from Microchip Technology offering similar 2Kb capacity and 3-Wire interface.
