FT93C66A-UTR-B

Overview

The FT93C66A-UTR-B is a non-volatile EEPROM memory integrated circuit manufactured by Fremont Micro Devices Ltd. It provides a storage capacity of 4Kb, organized as 512 x 8 or 256 x 16 bits. The device utilizes a 3-wire serial interface and supports a clock frequency of up to 2 MHz. It operates within a supply voltage range of 1.8V to 5.5V and functions across an industrial temperature range of -40°C to +85°C. The component is housed in an 8-TSSOP surface-mount package with a width of 4.40mm.

Feature Summary

• Supports dual word organization formats for flexible data addressing
• Operates on a wide supply voltage range suitable for low-power applications
• Features a compact surface-mount package design

Applications

• Industrial control systems requiring parameter storage
• Consumer electronics with limited pin count constraints
• Automotive embedded modules operating in harsh environments

Procurement Notes

Verify the specific suffix 'B' against official datasheets to confirm packaging and compliance details. Confirm that the 8-TSSOP footprint matches the target PCB layout. Ensure the 1.8V minimum supply voltage aligns with the system power rails. Check for RoHS3 compliance requirements relevant to the destination market.

Selection Notes

Select this component when a 4Kb capacity is required with a 3-wire interface. The 1.8V to 5.5V range allows compatibility with various logic levels. The TSSOP package is suitable for space-constrained designs. Verify that the 2 MHz speed meets the system timing requirements.

Part Context

This part belongs to the FT93C66A series of serial EEPROMs from Fremont Micro Devices Ltd. It serves as a drop-in replacement for standard 93C66A devices. The series offers non-volatile storage solutions for microcontroller-based systems. The UTR suffix indicates tape and reel packaging for automated assembly.
