The **M24C16-RBN3TP/S** is a specific variant of the M24C16 series, which is an I²C-compatible Electrically Erasable Programmable Read-Only Memory (EEPROM). It is manufactured by **STMicroelectronics**. --- ### 1. Key Technical Specifications Below are the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Memory Size** | 16 Kbit (2048 x 8 bits) | | **Interface** | I²C (Two-Wire Serial) | | **Clock Frequency** | 400 kHz (Fast Mode) | | **Supply Voltage (Vcc)** | 1.8V to 5.5V | | **Package Type** | DIP8 (Dual In-line Package) | | **Operating Temperature** | -40°C to +125°C | | **Write Cycles** | More than 4 million cycles | | **Data Retention** | Over 200 years | --- ### 2. Functional Description The device is organized as 128 pages of 16 bytes each. Since it is a 16-Kbit device, it uses the entire 3-bit device select code (A2, A1, A0) internally to address the memory blocks, meaning you generally cannot hardware-address multiple 16-Kbit chips on the same bus without specialized logic. #### Pin Configuration (DIP8) 1. **E0, E1, E2**: Chip Enable (Note: On the 16K version, these are typically NC or "Don't Care"). 2. **VSS**: Ground. 3. **SDA**: Serial Data (Bidirectional). 4. **SCL**: Serial Clock. 5. **WC**: Write Control (Hardware protection). 6. **VCC**: Supply Voltage. --- ### 3. Decoding the Part Number The suffix `RBN3TP/S` provides specific information regarding the manufacturing and packaging: | Code Segment | Meaning | | :--- | :--- | | **M24** | I²C Serial Access EEPROM | | **C16** | 16 Kbit Density | | **-R** | Operating Voltage: 1.8V to 5.5V | | **BN** | Package: PDIP8 (Plastic Dual In-line) | | **3** | Temperature Range: -40°C to +125°C | | **TP** | Tape & Reel Packing (or specialized processing) | | **/S** | Specific process/wafer variant (often indicates lead-free/RoHS or specific fab) | --- ### 4. Implementation Example To interface this EEPROM with a microcontroller (like an Arduino or STM32), you must use pull-up resistors on the SDA and SCL lines. ```cpp // Example: Basic Address Structure for I2C #define EEPROM_I2C_ADDRESS 0x50 // Base address for M24C16 void writeEEPROM(uint16_t address, uint8_t data) { Wire.beginTransmission(EEPROM_I2C_ADDRESS | (address >> 8)); Wire.write((uint8_t)(address & 0xFF)); // Low byte address Wire.write(data); Wire.endTransmission(); delay(5); // Minimum write cycle time } ```
