FT93C66A-ITR-B

Overview

The FT93C66A-ITR-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 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

• Supports dual memory organization formats for byte (x8) and word (x16) access
• Features a standard 3-wire serial interface compatible with Microwire protocols
• Includes hardware write protection mechanisms to prevent accidental data alteration

Applications

• Industrial control systems requiring parameter storage
• Consumer electronics configuration memory
• Automotive embedded applications

Procurement Notes

Verify the specific suffix 'B' against official datasheets to confirm exact packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with Fremont Micro Devices Ltd distributors, as availability may vary. Ensure the 1.8V to 5.5V operating voltage aligns with target system power rails before procurement.

Selection Notes

Select this component when a 4Kb EEPROM with a 3-wire interface is required in an 8-TSSOP package. It is suitable for designs needing wide voltage operation down to 1.8V. Compare against the FT93C46A series if only 1Kb capacity is sufficient, or the FT93C66A-UDR-B variant if through-hole DIP packaging is preferred instead of surface mount.

Part Context

This part belongs to the FT93Cx6A family of serial EEPROMs from Fremont Micro Devices Ltd. These devices are designed as drop-in replacements for industry-standard Microwire-compatible memories. The family offers various capacities and package options to support diverse embedded memory needs across industrial and commercial sectors.
