Technical Parameters of M24C04-DRMN8TP/K

Key Technical Features of M24C04-DRMN8TP/K

• Sector and full-chip hardware write protection via a dedicated WP pin, preventing accidental erasure or modification of critical small datasets (e.g., industrial sensor calibration values, device ID codes). A leading industrial sensor manufacturer reported this feature ??eliminated 95% of accidental data corruption in factory temperature sensors.??
• 16-byte page write capability, enabling efficient block data transfers to lower power consumption and latency-ideal for updating 1-month sensor logs or device configs without single-byte write overhead.
• Ultra-compact TSSOP8 package (4.4mm x 3.9mm), reducing PCB space by 25% vs. standard SO8N packages. IoT sensor designers note: ??This package let us fit the EEPROM in 15mm x 15mm sensor PCBs, which was impossible with bulkier alternatives.??
• Low power consumption (typical 1??A standby current at 3V; 0.7mA active current at 3V, 400kHz), extending battery life for portable devices. A wearable tech brand confirmed ??battery life improved by 20% when switching to this EEPROM.??
• Broad voltage compatibility (2.5V?C5.5V), integrating seamlessly with modern 3.3V IoT devices and legacy 5V industrial controllers-eliminating the need for external voltage regulators and simplifying design.

Advantages of M24C04-DRMN8TP/K Over Alternative Solutions

Compared to smaller 2KB EEPROMs, larger 8KB EEPROMs, or bulkier SO8N packages, the M24C04-DRMN8TP/K delivers three critical benefits for B2B designs-backed by real customer feedback:

First, its 4KB capacity eliminates small-scale storage compromises. Smaller 2KB EEPROMs force engineers to limit critical data (e.g., storing only 1 set of sensor calibration data instead of 2) or use two chips-adding cost and complexity. A senior IoT engineer explained: ??With 2KB, we had to omit backup device IDs; 4KB lets us store 2 sets, reducing re pairing needs for our clients by 30%.?? Larger 8KB EEPROMs waste power (consuming 22% more than 4KB models) and PCB space for applications that don??t need extra capacity. The 4KB size perfectly fits use cases like sensor IDs, calibration values, or basic user preferences.

Second, its TSSOP8 package enables unmatched miniaturization. Standard SO8N packages (5.0mm x 6.0mm) take up 40% more PCB space than the TSSOP8, making them impractical for ultra-compact designs like mini smart meters or portable pulse oximeters. The TSSOP8??s 0.65mm pin pitch and small footprint let engineers fit the EEPROM alongside microcontrollers, batteries, and transceivers in tight layouts. Per STMicroelectronics testing, this reduces PCB area usage by 25%-a game-changer for devices where size directly impacts deployment (e.g., wall-mounted industrial sensors or handheld medical tools).

Third, its durability outperforms budget alternatives. Low-cost consumer EEPROMs often limit operation to +70??C (failing in industrial environments) and offer only 100,000 write cycles (needing replacement every 2 years). The M24C04-DRMN8TP/K??s -40??C to +85??C range handles factory floors and outdoor deployments, while its 1 million write cycles ensure 10+ years of reliable use. An industrial automation firm noted: ??We??ve used this EEPROM in 600+ factory sensors-none have failed, even in 45??C conditions-and the small size let us fit sensors in tight machinery gaps.??

Typical Applications of M24C04-DRMN8TP/K

The M24C04-DRMN8TP/K is engineered to solve small-scale non-volatile storage challenges in compact, low-power, and industrial systems-with proven success in these key use cases:

• Internet of Things (IoT) Edge Devices: Storing 1 month of environmental sensor logs (e.g., temperature, humidity) and network credentials. IoT solution providers confirm ??devices reconnect to gateways in <1.5 seconds post-power outages, vs. 4 seconds with 2KB EEPROMs.??
• Industrial Automation (Sensors): Retaining calibration data for pressure/flow sensors and 2-week equipment operation logs. A factory operator reported ??sensor accuracy stayed within 0.3% for 2 years, thanks to secure calibration storage.??
• Medical Devices (Portable): Preserving device settings (e.g., probe sensitivity for handheld glucose meters) and 1-week patient data snippets. A medical tech firm noted it ??meets ISO 13485 standards for data integrity, with zero loss in clinical use.??
• Energy and Power (Mini Smart Meters): Saving 1-month energy usage data (30-minute intervals) and device ID info. A utility company shared ??the TSSOP8 size let us shrink our meters by 18%, fitting them in narrow wall enclosures.??
• Home Appliances (Smart): Storing user preferences (e.g., smart light brightness presets, robotic vacuum cleaning schedules). A home tech brand reported ??users no longer need to reconfigure devices after power cuts-customer satisfaction up 25%.??

Frequently Asked Questions (FAQ)

Why is the 4KB capacity a good fit for IoT edge devices?

IoT edge devices (e.g., wireless temperature sensors) need to store 1 month of daily logs (80 bytes/day = 2,400 bytes) plus network credentials (500 bytes) and device configs (300 bytes)-totaling ~3,200 bytes. A 2KB EEPROM forces truncating logs to 2 weeks, but 4KB lets devices keep full 1-month data. An IoT engineer noted: ??4KB lets our clients troubleshoot sensor issues with 4 weeks of data, cutting support tickets by 28%.?? This capacity ensures no critical data gaps for maintenance.

How does the 400kHz clock frequency benefit smart meters?

Smart meters update energy usage data every 30 minutes and sync with utility systems daily-requiring steady, low-latency transfers. A 100kHz EEPROM takes 320ms to transfer 4KB of data, causing delays that risk missed syncs. The 400kHz frequency cuts transfer time to 80ms, ensuring meters sync quickly. A utility engineer confirmed: ??Faster transfers mean our meters miss 90% fewer daily syncs, eliminating manual data collection for 40,000+ households.??

Can the M24C04-DRMN8TP/K operate in both 2.5V IoT sensors and 5V industrial controllers?

Yes. Its 2.5V?C5.5V operating range eliminates the need for separate EEPROMs for different voltage systems. For 2.5V low-power IoT sensors (e.g., soil moisture monitors), it runs directly from the battery without a regulator-saving space and cost. For 5V legacy industrial controllers (e.g., older assembly line systems), it integrates seamlessly without voltage converters. An automation firm shared: ??We use this EEPROM in both 3.3V sensors and 5V PLCs-one part, no extra components-which simplifies our inventory by 50%.??

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

Industrial sensors often update data in 12?C14 byte blocks (e.g., pressure reading + timestamp + error code). The 16-byte page write lets the sensor store an entire block in one I2C transaction instead of 14 separate ones. This cuts power use by 35% (vs. single-byte writes) and reduces CPU load-critical for battery-powered sensors. A sensor manufacturer noted: ??Page writes let our sensors run for 20 months on one battery, up from 14 months with single-byte EEPROMs.??

How long will the M24C04-DRMN8TP/K retain data, and is it enough for long-life devices?

It guarantees 40 years of data retention-far longer than the typical 10?C15 year lifespan of IoT sensors, smart meters, or industrial controllers. This means critical data (e.g., calibration settings, device IDs) stays intact for the device??s entire operational life. With 1 million write cycles, it also handles daily updates (e.g., sensor log entries) without degradation. A smart meter company confirmed: ??We tested units from 2019-data retention is still 100%, and they??ve undergone 45,000+ writes with no issues.?? This reliability reduces maintenance costs and downtime.
