FT24C08A-UTG-B

Overview

The FT24C08A-UTG-B is an 8Kb (1024 x 8) serial EEPROM from Fremont Micro Devices Ltd, housed in a TSSOP-8 package. It operates on a supply voltage of 1.8V to 5.5V and supports I²C interfaces with clock frequencies up to 1 MHz at 5V or 400 kHz at lower voltages. The device features industrial temperature range operation (-40°C to 85°C), self-timed write cycles of 5ms maximum, and hardware write protection via the WP pin.

Feature Summary

• Supports standard two-wire bi-directional serial interface for addressing read and write functions.
• Includes hardware data protection through a dedicated write protect pin that disables programming operations.
• Features automatic erase before write operations and partial page write capabilities within 16-byte pages.

Applications

• Low power consumer electronics requiring non-volatile memory storage.
• Industrial control systems operating within extended temperature ranges.
• Embedded devices utilizing I²C bus communication protocols.

Procurement Notes

Verify the specific ordering suffix 'B' indicates tube packaging rather than tape and reel. Confirm RoHS compliance status matches project requirements. Ensure the TSSOP-8 footprint aligns with PCB design constraints. Validate supply voltage compatibility across the full operational range.

Selection Notes

Select this component when 8Kb capacity and TSSOP-8 packaging are required. Consider the FT24C08A series for applications needing low standby current and wide voltage support. Evaluate the 1MHz speed capability if higher throughput is necessary compared to standard 400kHz limits.

Part Context

This part belongs to the FT24C08A series of serial EEPROMs manufactured by Fremont Micro Devices Ltd. The series includes variants with different package options such as DIP, SOP, DFN, and SOT-23. The UTG-B designation specifically identifies the TSSOP-8 package with Green RoHS compliant tubing.

FAQ

How does the Write Protect (WP) pin function?

Connecting the WP pin to VCC disables all programming functions, protecting the EEPROM array. Programming is allowed only when the pin is unconnected or connected to VIL.

What is the maximum write cycle time?

The self-timed write cycle has a maximum duration of 5ms, after which the device returns to standby mode.
