FT24C32A-UTG-B

Overview

The FT24C32A-UTG-B is a 32K-bit (4K x 8) CMOS serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 800 kHz and features a write cycle time of 5 ms. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an access time of 700 ns. It is housed in an 8-TSSOP package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed I²C communication up to 800 kHz for efficient data transfer.
• Provides non-volatile storage organized as 4K words of 8 bits each.
• Operates reliably across a wide industrial temperature range.

Applications

• Industrial control systems requiring persistent parameter storage
• Consumer electronics needing compact memory solutions
• Automotive modules utilizing standard I²C interfaces

Procurement Notes

Verify the specific suffix 'B' against official Fremont Micro Devices documentation to confirm exact packaging or tape-and-reel specifications. Ensure the 800 kHz speed grade matches system requirements. Confirm the TSSOP-8 footprint aligns with PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a 32K-bit capacity is required alongside fast 800 kHz I²C performance. It suits designs needing operation from 1.8 V to 5.5 V. Consider the 8-TSSOP package for space-constrained layouts. Verify compatibility with existing microcontroller I²C bus speeds and voltage levels.

Part Context

This part belongs to the FT24C series of serial EEPROMs from Fremont Micro Devices. It shares architectural similarities with other devices in the lineup, such as the FT24C256A, but offers lower density. The series focuses on providing reliable non-volatile memory with standard I²C connectivity for embedded applications.

Replacement Considerations

Cross-reference with FT24C32A-UTG-T if tape-and-reel packaging is preferred over bulk. Check M24C32 variants for pin-compatible alternatives with different voltage ranges or automotive qualifications.
