The **M24C16-RMB3TP/W** is a specific variant of an I²C (Inter-Integrated Circuit) Serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by **STMicroelectronics**. Below is a breakdown of its technical specifications and part number nomenclature. --- ## 1. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Memory Size** | 16 Kbit (2048 x 8 bits) | | **Interface** | I²C (Two-wire serial interface) | | **Clock Frequency** | 400 kHz (Fast Mode) | | **Supply Voltage (Vcc)** | 1.8V to 5.5V | | **Write Cycle Time** | 5 ms (Max) | | **Page Size** | 16 Bytes | | **Endurance** | 4 Million Write Cycles | | **Data Retention** | 200 Years | | **Operating Temperature** | -40°C to +125°C | --- ## 2. Part Number Breakdown Understanding the suffix codes is essential for identifying the specific physical characteristics of this component: ### **M24C16-RMB3TP/W** * **M24**: Standard I²C Serial Access EEPROM. * **C16**: 16 Kbit density. * **-R**: Range of operating voltage (1.8V to 5.5V). * **MB**: Package type, specifically **UFDFPN8** (Ultra-thin Fine pitch Dual Flat No-lead, 2x3 mm). * **3**: Temperature range (Device is tested for -40°C to +125°C). * **TP**: Packing style (Tape and Reel). * **/W**: Indicates a high-reliability process or specific wafer fab designation (often related to automotive or industrial robustness). --- ## 3. Key Electronic Features ### I²C Communication The device operates as a slave on the I²C bus. It requires only two signals: **SCL** (Serial Clock) and **SDA** (Serial Data). It supports multi-master environments and hardware write protection. ### Internal Organization The 16 Kbit memory is organized as 128 pages of 16 bytes each. When writing data, the device allows "Page Writes," which are more efficient than writing one byte at a time. ### Hardware Write Protection The device features a **Write Control (WC)** pin. * If **WC** is connected to Vcc, the entire memory becomes write-protected (Read-only). * If **WC** is connected to Ground (Vss), the memory can be written to normally. --- ## 4. Typical Applications * **Consumer Electronics:** Storing user preferences or calibration data in cameras and TVs. * **Industrial:** Parameter storage for sensors and controllers. * **Medical:** Data logging for portable medical devices. * **Automotive:** Storing configuration settings (due to the -40°C to 125°C temperature rating).
