The **M24C16-RMB6TP** is a specific variant of an I²C (Inter-Integrated Circuit) Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by **STMicroelectronics**. It is widely used for parameter storage in consumer electronics and industrial applications. --- ## 1. Technical Specifications The following table outlines the core electronic characteristics of the device: | Feature | Specification | | :--- | :--- | | **Memory Size** | 16 Kbit (2048 x 8 bits) | | **Interface** | I²C Serial (2-wire) | | **Operating Voltage** | 1.8V to 5.5V | | **Clock Frequency** | 400 kHz (Fast Mode) / 1 MHz (Fast Mode Plus) | | **Package Type** | UFDFPN8 (Ultra-thin Fine pitch Dual Flat No-lead) | | **Write Cycle Time** | 5 ms (Maximum) | | **Endurance** | 4 million Write cycles | | **Data Retention** | 200 years | --- ## 2. Pin Configuration The M24C16-RMB6TP typically utilizes an 8-pin layout. Because it is a 16 Kbit device, it handles addressing differently than smaller EEPROMs. | Pin Number | Name | Description | | :--- | :--- | :--- | | 1, 2, 3 | NC | Not Connected (Address pins E0-E2 are ignored for 16K density) | | 4 | VSS | Ground | | 5 | SDA | Serial Data (Bi-directional) | | 6 | SCL | Serial Clock (Input) | | 7 | WC | Write Control (Hardware Write Protection) | | 8 | VCC | Supply Voltage | --- ## 3. Key Electronic Functional Blocks ### A. I²C Protocol Logic The device acts as a **Slave** on the I²C bus. It requires a Start condition, an 8-bit device select code, and an acknowledgment bit. > **Note:** For the 16 Kbit version, the device address incorporates the three most significant bits of the memory array address, meaning it occupies all 8 available "slave addresses" on a single bus segment. ### B. Write Protection (WC Pin) This is a hardware safety feature: * **WC at VSS:** The entire memory is write-enabled. * **WC at VCC:** The entire memory is write-protected, preventing accidental data corruption. ### C. Page Write Mode To improve efficiency, the M24C16 supports **16-byte Page Write**. This allows the microcontroller to send up to 16 bytes in a single burst before the EEPROM begins its internal timed write cycle (5ms). --- ## 4.
