FT24C16A-UNR-T

Overview

The FT24C16A-UNR-T is a 16Kb (2048 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes a standard two-wire I2C interface with clock frequencies up to 1 MHz at 5V and 400 kHz at lower voltages. The device operates within a supply voltage range of 1.8V to 5.5V and supports industrial temperatures from -40°C to 85°C. Key electrical characteristics include a maximum standby current of 1µA, self-timed write cycles of 5ms, and high endurance ratings.

Feature Summary

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

Applications

• Data logging in low-power embedded systems
• Configuration storage for microcontrollers
• Calibration parameter retention

Procurement Notes

Verify the specific package suffix 'U' corresponds to the required industrial temperature range (-40°C to 85°C). Confirm that the 'N' packaging option aligns with the desired surface-mount footprint. Ensure the RoHS compliance status matches environmental regulations for the target assembly process.

Selection Notes

Select this component when a single device per bus is acceptable, as the FT24C16A lacks address pins for multi-device selection. Consider alternative densities like the FT24C08A or FT24C04A if multiple devices must share the same I2C bus lines due to their available chip select configurations.

Part Context

This part belongs to the FT24C04A/08A/16A series of two-wire serial EEPROMs. These devices are fabricated using advanced CMOS technology designed for low-voltage and low-power applications. The series offers various package options including DIP, SOP, TSSOP, DFN, MSOP, SOT-23, and TSOT-23.

FAQ

Can multiple FT24C16A devices be connected on the same I2C bus?

No, the FT24C16A does not utilize device address pins (A0-A2 are NC), allowing only one device per bus.

How is data protected from accidental writing?

The WP (Write Protect) pin disables all programming functions when connected to VCC or VIH, while read operations remain unaffected.
