FT93C56A-UTR-B

Overview

The FT93C56A-UTR-B is a non-volatile EEPROM memory IC manufactured by Fremont Micro Devices Ltd. It offers a storage capacity of 2Kbit, organized as 128 x 16 or 256 x 8 bits. The device features a 3-wire serial interface with a clock frequency of 2 MHz. It operates within a supply voltage range of 1.8V to 5.5V and supports an operating temperature range of -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
• Utilizes a simplified 3-wire serial interface for efficient communication
• Supports wide supply voltage operation from 1.8V to 5.5V
• Designed for industrial temperature ranges up to 85°C

Applications

• Embedded systems requiring small-scale parameter storage
• Industrial control devices needing configuration data retention
• Consumer electronics with limited pin count constraints
• Automotive modules operating in varying thermal conditions

Procurement Notes

Verify the specific suffix 'B' indicates RoHS compliance and lead-free status. Confirm the 'UTR' designation corresponds to the TSSOP tape-and-reel packaging format. Ensure the 2MHz clock speed requirement aligns with the host controller's capabilities. Check for any specific ordering prefixes required by the manufacturer for this variant.

Selection Notes

Select this component when 2Kbit capacity is required rather than the 1Kbit FT93C46A series. Choose the TSSOP package for surface-mount assembly needs. Ensure the system design accommodates the 3-wire interface protocol. Verify that the 1.8V minimum supply voltage meets the lowest system rail requirements.

Part Context

This part belongs to the FT93C56A family of serial EEPROMs. It shares architectural similarities with the FT93C46A but doubles the memory density. The device is designed as a drop-in replacement for standard 93C56 compatible parts. It maintains compatibility with common microcontroller peripheral interfaces.

Replacement Considerations

FT93C56A-UTR-T is a direct substitute differing only in reel packaging type.
