M95512-DFMC6TG EEPROM Memory IC 512Kbit SPI 16 MHz 8-UFDFPN (2x3)

Product Specification

Functions

1. Non-Volatile Data Storage: As an EEPROM, its core function is to store data permanently (non-volatilely), meaning data is retained even when the power supply is disconnected. It provides a storage capacity of 512 Kbits (equivalent to 64,000 bytes), suitable for storing configuration settings, user preferences, calibration data, or small datasets.
2. SPI Serial Interface: It communicates via a 4-wire Serial Peripheral Interface (SPI), supporting standard SPI modes (0,0 and 1,1). This interface enables simple integration with microcontrollers (MCUs), microprocessors (MPUs), and other digital devices, with a maximum clock frequency of up to 20 MHz for high-speed data transfer.
3. Flexible Read/Write Operations:
   • Random Read: Allows direct access and reading of data from any memory address, enabling efficient retrieval of specific information.
   • Page Write: Supports writing data to a 32-byte page (the maximum write unit) in a single operation, reducing communication overhead compared to byte-by-byte writing. Partial page writes are also allowed (without overwriting unselected bytes in the same page).
4. Write Protection Mechanism: It features hardware write protection to prevent accidental or unauthorized data modification. By connecting the WP (Write Protect) pin to GND or Vcc, users can protect the entire memory array or specific blocks (e.g., upper 1/4, upper 1/2, or all memory) from write operations, enhancing data security.
5. Low Power Consumption: Optimized for energy efficiency, it has extremely low active current (typically ~2 mA during read/write operations) and ultra-low standby current (typically ~1 μA when idle). This makes it ideal for battery-powered or energy-constrained devices.
6. High Durability and Data Retention: The device offers excellent endurance, supporting up to 1,000,000 (1M) write/erase cycles per memory page—ensuring long-term reliability in applications requiring frequent data updates. It also guarantees data retention for a minimum of 40 years, suitable for long-lifespan systems.
7. Wide Operating Conditions: It operates within a supply voltage range of 1.8 V to 5.5 V, providing compatibility with both low-voltage (e.g., 3.3 V) and standard-voltage (e.g., 5 V) electronic systems. It also functions reliably across a temperature range of -40°C to +85°C (industrial grade), adapting to harsh environmental conditions.
8. Compact Package: Encased in a small 8-pin DFN (Dual Flat No-Lead) package (3 mm x 3 mm), it occupies minimal printed circuit board (PCB) space, making it suitable for miniaturized and densely populated devices.

Applications

1. Industrial Automation:
   • PLCs and Industrial Controllers: Used to store configuration parameters (e.g., input/output settings, communication protocols), calibration data for sensors/actuators, and fault logs. Its write protection and durability ensure data integrity in harsh industrial environments.
   • Industrial Sensors: Stores sensor calibration coefficients (e.g., for temperature, pressure, or flow sensors) and measurement history, enabling accurate and consistent sensor readings over time.
2. Automotive Electronics:
   • Infotainment Systems: Stores user preferences (e.g., audio settings, display brightness, navigation favorites) and system configuration data. The wide voltage and temperature range ensures stability in vehicle environments.
   • Advanced Driver-Assistance Systems (ADAS): Stores calibration data for cameras, radar, or LiDAR modules, as well as temporary fault codes. Its non-volatile storage ensures critical data is not lost during power cycles.
   • Body Control Modules (BCMs): Stores settings for vehicle lighting, door locks, and climate control, supporting personalized user configurations.
3. Consumer Electronics:
   • Smart Home Devices: Used in smart thermostats, lighting controls, and security cameras to store user schedules, network credentials (e.g., Wi-Fi passwords), and device state information. Low power consumption extends battery life in wireless devices.
   • Wearable Technology: Stores fitness data (e.g., step counts, heart rate logs), user profiles, and device settings in smartwatches, fitness trackers, and health monitors. The compact package fits the miniaturized design of wearables.
   • Audio Equipment: Stores equalizer presets, volume levels, and connectivity settings in wireless speakers, headphones, and home theater systems.
4. Medical Devices:
   • Portable Medical Instruments: Stores patient data (e.g., blood glucose readings, blood pressure logs) and device calibration data in glucose meters, pulse oximeters, and portable ECG machines. Data retention and reliability are critical for clinical accuracy.
   • Medical Monitoring Systems: Stores device configuration and patient monitoring parameters, ensuring consistent operation and data traceability.
5. Internet of Things (IoT) Devices:
   • Wireless Sensor Nodes: Stores node IDs, network configuration (e.g., LoRa/NB-IoT parameters), and sensor data logs. Low power consumption and non-volatile storage support long-term, battery-powered IoT deployments.
   • Smart Meters: Stores energy usage data, meter identification information, and communication settings for electricity, water, or gas meters. Write protection prevents tampering with critical 计量 data.
6. Embedded Systems and Robotics:
   • Microcontroller-Based Projects: Serves as external non-volatile storage for MCUs with limited on-chip memory, storing firmware updates (temporarily or permanently), configuration files, and user data.
   • Robotics: Stores motion profiles, calibration data for motors/servos, and task sequences, ensuring consistent performance across power cycles.
