FT93C46A-ITR-B

Overview

The FT93C46A-ITR-B is a non-volatile EEPROM memory IC manufactured by Fremont Micro Devices Ltd. It features a storage capacity of 1Kb with an organization of 128 x 8 or 64 x 16 bits. The device utilizes a 3-wire serial interface and supports a maximum clock frequency of 2 MHz. It operates within a supply voltage range of 1.8V to 5.5V and functions across a temperature range of -40°C to 85°C. The component is housed in an 8-TSSOP surface-mount package.

Feature Summary

• Supports 3-wire serial communication interface for data access
• Provides non-volatile data retention without power
• Compatible with wide supply voltage ranges from 1.8V to 5.5V

Applications

• Embedded systems requiring small-scale non-volatile storage
• Industrial control devices operating in extended temperature environments
• Consumer electronics utilizing low-voltage power supplies

Procurement Notes

Verify the specific suffix 'B' against official datasheets to confirm package dimensions and tape-and-reel specifications, as distributor listings may contain generic descriptions. Confirm RoHS compliance status directly with the manufacturer documentation before integration into regulated assemblies. Ensure the 8-TSSOP footprint matches the target PCB design constraints.

Selection Notes

Select this component when a 1Kb EEPROM with a 3-wire interface is required. Compare against alternatives like the FT93C46A-UTR-B if different packaging options are needed. Verify that the 2 MHz clock speed meets system timing requirements. Check for availability issues as some distributors list this part as discontinued or out of stock.

Part Context

This part belongs to the FT93C46A series of EEPROMs from Fremont Micro Devices Ltd. It is functionally related to other industry-standard 93C46A devices but uses Fremont's specific manufacturing processes. The ITR suffix indicates the tape-and-reel packaging format, while B denotes the specific variant details.

Replacement Considerations

FT93C46A-UTR-B is listed as a direct substitute. AT93C46D-TH-B and AT93C46D-TH-T from Microchip Technology are also identified as compatible alternatives.
