Key Features
- 256-Kbit (32 KB) I2C serial EEPROM offering non-volatile data storage on a 2-wire bus with up to 400 kHz fast-mode operation
- Configurable device address pins enabling up to 8 devices on a single I2C bus without address conflicts
- Software write-protection feature allowing firmware to lock memory regions against accidental overwrites during critical operations
- Ultra-compact 4-ball WLCSP package with sub-millimeter footprint ideal for space-constrained wearable and IoT designs
- Low-voltage operation compatible with 1.7 V to 5.5 V supply rails for broad system compatibility
Applications
The M24256X-FCU6T/VF is used in wearable devices, IoT sensors, and portable medical equipment where ultra-small non-volatile memory with I2C connectivity is required in the tightest PCB footprints. Its configurable address lines allow multiple EEPROM instances on a single bus, supporting applications such as calibration data storage, configuration parameter retention, and firmware settings in multi-node systems. The software write protection makes it ideal for safety-critical applications storing factory calibration or security certificates.

Frequently Asked Questions
How large is the M24256X-FCU6T/VF memory, and what interface does it use for communication?
The M24256X-FCU6T/VF provides 256 Kbits (32 KB) of non-volatile EEPROM storage accessed via a 2-wire I2C serial bus supporting standard mode (100 kHz) and fast mode (400 kHz) operation. This makes it easy to integrate with virtually any microcontroller with an I2C peripheral.
What advantage does the configurable device address offer when using multiple M24256X-FCU6T/VF devices on the same I2C bus?
The configurable address pins on the M24256X-FCU6T/VF allow up to 8 separate devices to coexist on a single I2C bus by assigning unique 3-bit addresses to each. This is valuable in multi-channel data loggers, distributed sensor nodes, or modular designs requiring 32 KB × 8 = 256 KB of total addressable EEPROM storage.
How does the software write-protection feature of the M24256X-FCU6T/VF protect stored data in embedded systems?
The software write-protection feature allows firmware to lock designated memory regions via a write-protect control mechanism, preventing accidental overwrites during system operation. This is critical for applications storing factory calibration constants, security certificates, or device configuration data that must remain intact across power cycles and firmware updates.
What makes the WLCSP package of the M24256X-FCU6T/VF suitable for compact IoT and wearable designs?
The 4-ball WLCSP (Wafer-Level Chip Scale Package) of the M24256X-FCU6T/VF occupies a sub-millimeter footprint, significantly smaller than SOT or SOIC packages. This minimal PCB area consumption is essential for wearables, hearing aids, smart patches, and other miniaturized IoT devices where every square millimeter of board space is at a premium.
