FT24C08A-UTR-B

Overview

The FT24C08A-UTR-B is an 8K-bit (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 mode with partial page write capability for efficient data programming.
• Includes Schmitt triggers and filtered inputs on all pins to provide enhanced noise protection.
• Features automatic erase-before-write functionality to simplify the programming sequence.
• Provides hardware data protection through a dedicated Write Protect (WP) pin.

Applications

• Data logging systems requiring non-volatile storage
• Configuration memory for embedded controllers
• Parameter storage in industrial instrumentation

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'U' indicates the -40°C to 85°C temperature range, 'T' specifies Tape and Reel packaging, and 'B' denotes RoHS compliance. Confirm the package type is TSSOP-8. Ensure the design accounts for the specific address pin configuration where A1 and A0 are not connected for this device family.

Selection Notes

Select this component when an 8K-bit capacity is required with a low-profile surface mount package. The TSSOP-8 form factor suits space-constrained designs. Verify that the system bus speed requirements align with the 400 kHz limit if operating below 2.7V. Consider the hardware write protect feature if security against accidental overwrites is necessary.

Part Context

This part belongs to the FT24C04A/08A/16A series of serial EEPROMs. These devices share a common architecture and interface protocol but differ in memory density and available address pins. The FT24C08A specifically utilizes only the A2 pin for addressing, allowing two devices on a single bus.
