FT24C02A-USG-T

Overview

The FT24C02A-USG-T is a 2Kb (256 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It features an I²C interface with a maximum clock frequency of 1 MHz at 5V and 400 kHz at 1.8V. The device operates within a supply voltage range of 1.8V to 5.5V and supports an industrial temperature range from -40°C to +85°C. Key electrical parameters include a standby current of less than 1µA, a write cycle time of 5ms maximum, and an endurance rating of 1,000,000 cycles. It utilizes a TSSOP-8 package.

Feature Summary

• Supports standard two-wire bi-directional serial interface compatible with I²C bus modes.
• Includes hardware write protection via the WP pin to prevent unauthorized programming.
• Features 16-byte page write mode allowing partial page operations for efficient data handling.

Applications

• Consumer electronics requiring low power non-volatile storage
• Industrial control systems operating in wide temperature ranges
• Communication equipment needing reliable parameter retention

Procurement Notes

Verify that the ordering suffix 'USG' corresponds to the SOP-8 package, Green option, and Tape & Reel packaging as defined in the manufacturer's order code table. Confirm RoHS compliance status matches project requirements. Ensure the specific revision level aligns with design specifications before finalizing procurement orders.

Selection Notes

Select this component when an 8-pin surface-mount solution is required for multi-device I²C bus configurations. The 'U' series designation ensures all address pins are available for chip selection, unlike the '5' series which limits bus scalability. Verify that the 1.8V minimum operating voltage meets the system's lowest supply rail constraints during operation.

Part Context

This part belongs to the FT24C02A family of 2Kbit serial EEPROMs produced by Fremont Micro Devices Ltd. The family offers various package options including DIP, SOIC, TSSOP, DFN, and SOT-23. The USG variant specifically denotes the SOP-8 package configuration with green compliant materials and tape-and-reel delivery format.

FAQ

What is the difference between the FT24C02A-5xx and FT24C02A-Uxx versions?

The FT24C02A-5xx version has only 5 valid pins and is suitable for applications with only one EEPROM on the bus. The FT24C02A-Uxx version has 8 valid pins, making it suitable for all applications, including those with multiple EEPROMs on the same I²C bus.

How does the Write Protect (WP) pin function?

The WP pin protects the entire EEPROM array from programming. Programming is allowed if WP is unconnected or at VIL. All programming functions are disabled if WP is connected to VIH or VCC, though read operations remain unaffected.
