FT24C32A-UMR-B

Overview

The FT24C32A-UMR-B is a 32-Kbit serial I2C bus EEPROM manufactured by Fremont Micro Devices USA. It is organized as 4 K x 8 bits and supports standard, fast, and fast mode plus I2C protocols with clock frequencies up to 1 MHz. The device operates within a supply voltage range of 1.7 V to 5.5 V and is housed in an 8-pin MSOP package. It features enhanced ESD protection, hardware write protection capabilities, and high endurance with over four million write cycles and more than 200 years of data retention.

Feature Summary

• Supports I2C bus modes including 100 kHz, 400 kHz, and 1 MHz for flexible system integration
• Provides hardware write protection to secure specific memory sections against unauthorized modification
• Offers high reliability with extended data retention and significant write cycle endurance

Applications

• Consumer electronics requiring non-volatile configuration storage
• Industrial control systems needing reliable parameter retention
