FT93C66A-UTR-T

Overview

The FT93C66A-UTR-T 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 bits or 256 x 16 bits. The device utilizes a 3-wire serial interface and supports clock frequencies up to 2 MHz. It operates within a supply voltage range of 1.8V to 5.5V and functions at temperatures between -40°C and +85°C. The component is housed in an 8-TSSOP package with a width of 4.40mm and features a write cycle time of 10ms.

Feature Summary

Supports dual memory organization for both byte (x8) and word (x16) access modes
Operates across a wide supply voltage range from 1.8V to 5.5V
Includes READY/BUSY signal functionality during programming cycles

Applications

Data storage in industrial control systems
Configuration memory for embedded devices
Parameter storage in automotive electronics

Procurement Notes

Verify the specific suffix UTR-T corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the 1.8V minimum operating voltage aligns with the target system's power rail specifications. Ensure the 8-TSSOP footprint matches the design layout constraints. Cross-reference the manufacturer part number with official distributor catalogs to confirm current availability status and lead times.

Selection Notes

Select this component when a 4Kb EEPROM with 3-wire serial interface is required in a surface-mount TSSOP package. It is suitable for applications needing operation down to 1.8V. Compare against the FT93C66A-IDR-B if through-hole DIP packaging is preferred instead of surface mount. Consider the FT93C46A series if only 1Kb capacity is sufficient for the application.

Part Context

This part belongs to the FT93Cx6A family of Microwire-compatible EEPROMs from Fremont Micro Devices Ltd. It serves as a pin-to-pin compatible alternative to industry-standard parts like the AT93C66B. The family offers various capacities and packaging options to support diverse embedded memory needs.
