Technical Parameters of M24C04-FMN6TP

Key Technical Features of M24C04-FMN6TP

• Hardware write protection via a dedicated WP pin, preventing accidental erasure or modification of critical data (e.g., industrial process settings, medical device calibration values) in high-reliability systems.
• Self-timed write cycles (up to 5ms), eliminating the need for external timing circuits and simplifying software integration-reducing design complexity and shortening time-to-market for engineers.
• 16-byte page write capability, enabling efficient block data transfers to reduce system latency and lower power consumption during bulk updates (e.g., storing hourly sensor logs in IoT devices).
• Ultra-low standby current (typical 1??A at 3V) and low active current (typical 1mA at 3V, 1MHz), optimizing power efficiency for battery-powered devices where extended operational life is critical.
• Lead-free (RoHS compliant) TSSOP8 package, meeting global environmental standards and ensuring compatibility with modern high-volume surface-mount assembly processes.

Advantages of M24C04-FMN6TP Over Alternative Solutions

Compared to smaller EEPROMs (1KB/2KB), standard SO8-packaged memory, or narrow-voltage-range alternatives, the M24C04-FMN6TP delivers three critical benefits for B2B designs:

First, its 4KB capacity balances storage needs and efficiency. Smaller 1KB/2KB EEPROMs force engineers to limit data logging (e.g., truncating sensor history) or reduce configuration complexity, while larger 8KB+ options waste space and increase cost. The 4KB capacity is ideal for applications like smart thermostats (storing weekly usage patterns) or industrial sensors (saving multi-setting parameters), eliminating compromises between storage and cost.

Second, its TSSOP8 package enables superior miniaturization. Standard SO8 packages occupy ~30mm2 of PCB space, which is impractical for compact designs like IoT gateways or portable medical monitors. The TSSOP8??s 17.2mm2 footprint saves 30% of board space, letting engineers integrate more features (e.g., additional sensors) without increasing product size-critical for consumer and medical devices where form factor directly impacts usability.

Third, its wide voltage range and durability outperform budget alternatives. Low-cost EEPROMs often restrict operation to 3.3V only (requiring external regulators for 1.8V/5V systems) and offer just 100,000 write cycles. The M24C04-FMN6TP??s 1.8V?C5.5V range works with legacy 5V industrial controllers and modern 1.8V IoT microcontrollers, while its 1 million write cycles and 40-year retention ensure long-term reliability-reducing maintenance costs for end products.

Typical Applications of M24C04-FMN6TP

The M24C04-FMN6TP is engineered to solve mid-scale non-volatile storage challenges in compact, battery-powered, or industrial systems. Its key use cases include:

• Internet of Things (IoT): Storing sensor data logs (e.g., 24-hour environmental readings), network credentials, and device metadata in compact IoT gateways-enabling continuous monitoring without data loss during power cycles.
• Medical Devices (Portable): Preserving patient-specific data (e.g., 7-day blood pressure trends) and device calibration settings in handheld monitors-complying with healthcare standards for data integrity and supporting accurate patient care tracking.
• Industrial Automation: Retaining PLC operational parameters (e.g., motor speed setpoints, alarm thresholds) and short process logs in compact factory sensors-withstanding industrial temperatures and ensuring uninterrupted production during power outages.
• Consumer Electronics (Wearables): Saving user profiles (e.g., fitness goals, audio preferences) and activity logs in wireless wearables (e.g., smart bands)-delivering personalized experiences while fitting into ultra-slim designs.
• Home Appliances (Smart): Storing weekly usage patterns (e.g., smart thermostat temperature schedules) and device configs-optimizing energy efficiency and ensuring consistent comfort even after power disruptions.

Frequently Asked Questions (FAQ)

Why is the 4KB capacity a good fit for smart thermostats?

Smart thermostats need to store mid-scale data: weekly temperature schedules (typically 7 days x 24 hours = 168 data points), user preferences, and energy usage logs. 1KB/2KB EEPROMs are too small to hold this data, while 8KB+ options are unnecessary. The 4KB capacity perfectly matches these needs, ensuring efficient storage without wasting space or increasing cost.

How does the TSSOP8 package improve design for IoT gateways?

IoT gateways often need to connect multiple sensors and modules in a small enclosure. The TSSOP8 package??s 4.4mm x 3.9mm size is 30% smaller than standard SO8, freeing up PCB space for other components (e.g., Wi-Fi modules, additional sensors). This smaller footprint also lets manufacturers use smaller enclosures, reducing overall product size and cost-critical for IoT deployments where space is limited.

Can the M24C04-FMN6TP operate in both 1.8V IoT devices and 5V industrial systems?

Yes. Its 1.8V?C5.5V operating range eliminates the need for separate EEPROMs for different voltage platforms. For 1.8V IoT microcontrollers (e.g., ESP32-C3), it runs directly from the battery without a regulator; for 5V industrial PLCs, it integrates seamlessly with legacy hardware. This flexibility simplifies inventory management and reduces design time for engineers working across multiple projects.

What is the benefit of the 16-byte page write feature for industrial sensors?

Industrial sensors often log data at regular intervals (e.g., hourly temperature readings). The 16-byte page write lets the sensor store 16 bytes of data in one I2C transaction instead of 16 separate transactions. This cuts power use (fewer active cycles) and reduces latency (faster data storage), ensuring the sensor can log data quickly and efficiently-even with limited battery power in remote deployments.

How long will the M24C04-FMN6TP retain data, and is it enough for industrial applications?

It guarantees 40 years of data retention, far exceeding the typical 15?C20 year lifespan of industrial equipment (e.g., PLCs, sensors). This ensures critical data (e.g., calibration settings, process logs) remains intact for the product??s entire operational life. With 1 million write cycles, it also handles frequent updates (e.g., daily parameter adjustments) without degradation-meeting industrial reliability standards and reducing downtime.
