FT93C56A-ITR-B

Overview

The FT93C56A-ITR-B is a non-volatile EEPROM memory integrated circuit manufactured by Fremont Micro Devices Ltd. It offers a storage capacity of 2Kbit, organized as 256 words of 8 bits or 128 words of 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 reliable non-volatile data retention for embedded applications
• Supports high-speed serial communication via a 3-wire interface
• Operates across a wide voltage range suitable for low-power systems

Applications

• Embedded system configuration storage
• Industrial control parameter logging
• Consumer electronics calibration data retention

Procurement Notes

Verify the specific suffix 'ITR-B' corresponds to the tape-and-reel packaging format and the 8-TSSOP footprint. Confirm that the manufacturer's current status aligns with project requirements, as availability may vary. Ensure compatibility with existing PCB silkscreen and assembly processes for the specified package type before finalizing procurement orders.

Selection Notes

Select this component when a 2Kbit EEPROM size is required with a 3-wire interface rather than SPI. The 1.8V to 5.5V operating range allows flexibility in power supply design. The 8-TSSOP package is appropriate for space-constrained surface-mount designs requiring industrial temperature stability.

Part Context

This part belongs to the 93C46A/56A/66A series of serial EEPROMs. The '56A' designation indicates the 2Kbit density level. The 'ITR' suffix typically denotes the tape-and-reel packaging variant, while 'B' often signifies lead-free/RoHS compliance. This series serves as a drop-in replacement for legacy Micromax devices.

Replacement Considerations

• FT93C56A-UTR-B
• AT93C56D-TH-T
