FT24C16A-UDR-B

Overview

The FT24C16A-UDR-B is a 16Kb (2048 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes a standard two-wire I2C interface and operates within a supply voltage range of 1.8V to 5.5V. The device supports clock frequencies up to 1 MHz at 5V and 400 kHz at lower voltages, with an access time of 550 ns. It features a self-timed write cycle of 5 ms maximum and includes hardware data protection via a Write Protect pin. The component is housed in an 8-pin DIP package and is rated for industrial temperatures from -40°C to 85°C.

Feature Summary

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

Applications

• Data storage in low-power embedded systems
• Configuration memory for microcontrollers
• Industrial control system parameter logging

Procurement Notes

Verify that the specific ordering suffix matches the required package type and compliance standards. Confirm the RoHS status aligns with project requirements. Ensure the temperature range specification meets environmental operating conditions. Validate the lead finish against soldering process compatibility. Cross-reference the datasheet revision to ensure accurate electrical characteristics are applied during design.

Selection Notes

Select this component when a 16Kb non-volatile memory solution is required with a simple two-wire interface. Consider the 1.8V to 5.5V operating range for versatile power supply integration. Evaluate the 1 MHz clock speed for high-throughput applications. Verify that the 8-pin DIP package fits the available board space and assembly method constraints.

Part Context

This part belongs to the FT24C16A series of serial EEPROMs from Fremont Micro Devices. The series offers varying densities including 4Kb and 8Kb options. All variants share the same I2C protocol and core architecture but differ in address pin configurations and physical packaging options such as SOP, TSSOP, and DFN.

FAQ

How many devices can be connected on the same bus?

Only one FT24C16A device can be used on a single 2-wire bus because it does not utilize device address bits.

What is the function of the WP pin?

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