FT24C02A-5LR-T

Overview

The FT24C02A-5LR-T is a 2Kb (256 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It operates within a supply voltage range of 1.8V to 5.5V and supports I2C interfaces at maximum clock frequencies of 1MHz at 5V and 400kHz at lower voltages. The device features a 550ns access time, a 5ms write cycle duration, and an endurance rating of 1,000,000 cycles. It utilizes a 5-pin SOT-23 package with surface mount installation and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports 16-byte page write operations with partial page write capability for efficient data management.
• Includes hardware write protection via the WP pin to prevent unintended memory array programming.
• Features Schmitt trigger inputs and noise filtering to ensure signal integrity on the serial bus.

Applications

• Data logging in low-power embedded systems
• Configuration storage for microcontroller-based devices
• Calibration parameter retention in consumer electronics

Procurement Notes

Verify that the specific ordering suffix matches the required package type and compliance standards. Confirm the device version aligns with system bus topology requirements, as this variant restricts single-device usage per bus. Ensure compatibility with the target operating voltage and temperature specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact footprint is required for small-scale non-volatile storage needs. The 5-pin SOT-23 package offers space efficiency compared to standard 8-pin options. Consider the single-device bus limitation during system architecture planning to avoid address conflict issues inherent to this specific pin configuration.

Part Context

This part belongs to the FT24C02A series of two-wire serial EEPROMs designed for low-voltage applications. The manufacturer utilizes advanced CMOS processes to achieve low power consumption. The series provides various packaging options to accommodate different board layout constraints while maintaining consistent electrical performance characteristics.

FAQ

Can multiple FT24C02A-5xx devices be used on the same I2C bus?

No, the FT24C02A-5xx version does not support external address pins and is limited to one device per bus.

How does the Write Protect pin function?

Connecting the WP pin to VCC disables all programming functions, protecting the memory array from writes while allowing reads.
