FT25C32A-UTR-B

Overview

The FT25C32A-UTR-B is a 32Kbit Serial Peripheral Interface (SPI) EEPROM memory IC manufactured by Fremont Micro Devices Ltd. It features a non-volatile storage capacity of 32Kb organized as 4096 words of 8 bits. The device supports a maximum clock frequency of 20MHz and operates within a supply voltage range of 1.8V to 5.5V. It utilizes an SPI interface type and has a write cycle time of 5ms. The component is housed in an 8-TSSOP package with surface mount installation. It functions reliably across a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Supports high-speed serial communication via the SPI interface with a maximum clock frequency of 20MHz.
• Provides non-volatile data retention using Electrical Erasable and Programmable Read Only Memory technology.
• Operates across a broad supply voltage range from 1.8V to 5.5V for flexible system integration.

Applications

• Data logging systems requiring persistent storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in industrial sensors

Procurement Notes

Verify the specific suffix 'UTR-B' against the manufacturer's official datasheet to confirm pinout, packaging dimensions, and electrical characteristics match your design requirements. Ensure compatibility with your system's SPI protocol implementation and voltage levels before finalizing procurement decisions.

Selection Notes

Select this component when a small, high-speed SPI EEPROM is required for non-volatile storage. It is suitable for applications needing 32Kbit capacity with fast access times. Consider the 8-TSSOP package constraints and the 1.8V to 5.5V operating range during circuit design.

Part Context

This part belongs to the FT25C series of SPI EEPROMs from Fremont Micro Devices. It offers a compact solution for storing small amounts of data that must persist without power. The series is designed for general-purpose memory applications in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other 32Kbit SPI EEPROMs from Fremont such as the FT25C64A or FT25C128 if higher capacity is acceptable. Verify pin compatibility and voltage ranges when considering alternatives from other manufacturers.
