FT93C56A-USR-T

Overview

The FT93C56A-USR-T is a non-volatile EEPROM memory integrated circuit manufactured by Fremont Micro Devices Ltd. It features a 2Kbit storage capacity organized as 256 x 8 or 128 x 16 bits. The device utilizes a 3-wire serial interface and operates with a clock frequency of up to 2 MHz. It is housed in an 8-SOIC surface-mount package with a width of 0.154 inches (3.90mm). The component supports a supply voltage range of 4.5V to 5.5V and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Built-in write enable latch for secure data protection
• High endurance with 1,000,000 write cycle capability
• Long-term data retention characteristics

Applications

• Embedded systems requiring small non-volatile data storage
• Industrial control devices needing parameter retention
• Consumer electronics with configuration memory needs

Procurement Notes

Verify the specific suffix 'USR-T' confirms the 8-SOIC surface mount package and tape-and-reel packaging format. Ensure compatibility with 3-wire serial protocols and 5.5V maximum supply limits. Confirm RoHS3 compliance status if required for your manufacturing process. Cross-reference the manufacturer part number with authorized distributor listings to ensure authenticity and correct revision level.

Selection Notes

Select this component when a surface-mount EEPROM with 2Kbit capacity is required. The 8-SOIC package suits space-constrained PCB designs. Verify that the system interface supports the 3-wire serial protocol and that the 2 MHz clock speed meets timing requirements. Ensure the operating temperature range covers the intended environmental conditions.

Part Context

This part belongs to the FT93CxxA series of serial EEPROMs from Fremont Micro Devices. These devices are designed for low-power applications and offer reliable data retention. The USR-T variant specifically denotes the surface-mount SOIC package and reel packaging, distinguishing it from through-hole DIP alternatives in the same family.

Replacement Considerations

FT93C56A-UDR-B is listed as a similar alternative but uses a different 8-DIP through-hole package. Ensure mechanical fitment and mounting type compatibility before substitution. Other variants like FT93C46A or FT93C66A have different memory capacities and may not be direct functional replacements.
