FT24C16A-UMR-B

Overview

The FT24C16A-UMR-B is a 16K-bit 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 lower voltages. The device operates on a single supply voltage ranging from 1.8V to 5.5V. It supports page write operations with a 16-byte page size and includes hardware write protection via the WP pin. The memory organization consists of 2048 words of 8 bits each, housed in an 8-pin MSOP package.

Feature Summary

• Supports standard two-wire bi-directional serial interface for data transfer
• Includes hardware write protect capability to secure memory array
• Features self-timed internal programming cycles for automatic erase before write
• Provides low power standby operation with Schmitt trigger inputs for noise immunity

Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in industrial sensors
• Device identification and serial number storage

Procurement Notes

Verify that the ordering suffix UMR-B corresponds to the specified MSOP package, RoHS compliance, and tube packaging format as defined in the manufacturer's datasheet. Confirm the component matches the FT24C16A series specifications regarding voltage range and interface compatibility before integration into the design.

Selection Notes

Select this component when a 16K-bit capacity is required within a compact surface-mount footprint. Ensure the system design accommodates the specific address pin configuration where A0, A1, and A2 are not utilized for bus addressing. Verify that the application environment remains within the specified industrial temperature range and voltage limits.

Part Context

This part belongs to the FT24C04A/08A/16A family of serial EEPROMs from Fremont Micro Devices. These devices share common architectural features including the I2C protocol and low-voltage CMOS technology. The FT24C16A variant specifically offers higher density compared to its 4K and 8K counterparts while maintaining identical pinouts and operational characteristics.

Replacement Considerations

Compatible substitutes include other 16K-bit I2C EEPROMs from manufacturers such as Microchip (e.g., 24LC16 series) or STMicroelectronics (e.g., M24C16 series). Ensure functional equivalence regarding voltage range, interface timing, and package dimensions before substitution.
