FT24C08A-UTG-T

Overview

The FT24C08A-UTG-T is an 8Kbit (1024 x 8) serial EEPROM from Fremont Micro Devices Ltd, utilizing a standard two-wire I2C interface. It operates within a supply voltage range of 1.8V to 5.5V and supports clock frequencies up to 1 MHz at 5V or 400 kHz at lower voltages. The device features a self-timed write cycle with a maximum duration of 5 ms and includes hardware write protection via the WP pin. It is housed in an 8-pin TSSOP package and complies with RoHS standards.

Feature Summary

• Supports 16-byte page write operations with partial page write capability.
• Includes Schmitt trigger inputs and noise filtering for signal integrity.
• Features automatic erase-before-write functionality during programming cycles.
• Provides hardware data protection through a dedicated write protect pin.

Applications

• Low power embedded systems requiring non-volatile data storage
• Industrial control units operating in wide temperature ranges
• Consumer electronics utilizing I2C bus communication

Procurement Notes

Verify that the ordering suffix 'UTG' corresponds to the specific TSSOP-8 package and Green RoHS-compliant variant required for your design. Confirm the tape and reel packaging option matches your automated assembly equipment specifications before finalizing procurement orders.

Selection Notes

Select this component when an 8Kbit capacity is required alongside a compact surface-mount footprint. Ensure the system design accommodates the 1.8V minimum supply voltage if operating in low-power modes. Verify that the I2C bus pull-up resistors are correctly sized for the desired clock frequency and bus capacitance limits.

Part Context

This part belongs to the FT24C04A/08A/16A series of two-wire serial EEPROMs manufactured by Fremont Micro Devices Ltd. The series shares common electrical characteristics and interface protocols, differing primarily in memory density and available address pins. The FT24C08A specifically utilizes one device address pin to allow multiple devices on a single bus.

FAQ

How many FT24C08A devices can be connected to a single I2C bus?

Only two FT24C08A devices can be wired-OR on the same bus, as they utilize only one device address bit (A2).

What is the function of the Write Protect (WP) pin?

The WP pin disables all programming functions when connected to VCC or VIH, protecting the EEPROM array from accidental writes while allowing read operations.
