FT24C02A-5PR-T

Overview

The FT24C02A-5PR-T is a 2Kbit (256 x 8) serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) manufactured by Fremont Micro Devices Ltd. It operates within a supply voltage range of 1.8V to 5.5V and supports an industrial temperature range from -40°C to +85°C. The device utilizes a standard two-wire I2C serial interface with a maximum clock frequency of 1 MHz at 5V and 400 kHz at lower voltages. It features a write cycle time of 5 ms, hardware data protection via a Write Protect pin, and low standby current typically below 1 µA.

Feature Summary

• Supports 16-byte page write mode with partial page write capability for flexible data management.
• Includes a dedicated Write Protect pin to prevent accidental programming of the memory array.
• Features Schmitt trigger inputs and noise filtering to ensure signal integrity on the serial bus.
• Provides automatic erase before write operations and acknowledge polling during self-timed programming cycles.

Applications

• Data logging in battery-powered devices requiring low standby current
• Configuration storage in microcontroller systems using I2C interfaces
• Parameter retention in industrial sensors operating across wide temperature ranges

Procurement Notes

Verify that the specific ordering suffix matches the required package type and compliance status. Confirm the component is the '-5xx' version, which has five valid pins and lacks device address inputs, restricting usage to single-device I2C buses. Ensure the RoHS compliant option is selected if environmental regulations apply to the assembly process.

Selection Notes

Select this component when a cost-effective solution is needed for applications requiring only one EEPROM on the I2C bus. The '-5xx' designation indicates a simplified pinout suitable for space-constrained designs where multiple device addressing is unnecessary. Verify compatibility with the system's voltage levels and I2C clock speed requirements before integration.

Part Context

This part belongs to the FT24C02A family of 2Kbit serial EEPROMs. The '5P' suffix denotes the TSOT-23-5 surface-mount package variant. The 'R' indicates RoHS compliance. This specific configuration offers a compact footprint while maintaining the full functional capabilities of the base FT24C02A architecture, excluding multi-device addressing features.

FAQ

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

No, the '-5xx' version does not support external device address inputs. Only one such device can be connected to a single I2C bus.

What is the function of the WP pin?

The Write Protect (WP) pin disables all programming functions when held high, protecting the memory array from being overwritten while allowing read operations.
