## M24C16-RBN6TP: Electronic Specifications and Overview The **M24C16-RBN6TP** is a 16-Kbit serial I²C (Inter-Integrated Circuit) EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by **STMicroelectronics**. It is widely used for non-volatile parameter storage in consumer electronics and industrial applications. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Memory Size** | 16 Kbit (2,048 bytes) | | **Memory Organization** | 2048 x 8 bits (split into 8 blocks of 256 bytes) | | **Interface** | I²C Serial (2-wire) | | **Clock Frequency** | 400 kHz (Fast Mode) | | **Operating Voltage (Vcc)** | 1.8V to 5.5V | | **Package Type** | PDIP8 (Plastic Dual In-line Package) | | **Operating Temperature** | -40°C to +85°C | | **Write Cycles (Endurance)** | 1 Million write cycles (minimum) | | **Data Retention** | 40 Years (minimum) | --- ### 2. Pin Configuration The M24C16-RBN6TP typically follows the standard 8-pin EEPROM pinout: 1. **E0, E1, E2 (Chip Enable):** These are physically present but, for the 16-Kbit version, they are "Don't Care" (NC) because the internal addressing uses these bits to select memory blocks. 2. **Vss:** Ground. 3. **SDA (Serial Data):** Bidirectional pin used to transfer data in and out. 4. **SCL (Serial Clock):** Used to synchronize data transfer. 5. **WC (Write Control):** Hardware write protection. If connected to Vcc, write operations are inhibited. If connected to Vss, write operations are allowed. 6. **Vcc:** Power supply. --- ### 3. Core Functional Features * **Byte and Page Write:** Supports writing a single byte or a page of up to 16 bytes. * **Random and Sequential Read:** Allows reading from a specific address or streaming data sequentially across the entire memory. * **Internal Addressing:** The 16-Kbit memory is organized into 8 blocks of 256 bytes each. The device address (sent via I²C) includes 3 bits that act as the high-order address bits to select one of these 8 blocks. * **Low Power Consumption:** * Active Read Current: < 1 mA * Standby Current: < 1 µA (at 1.8V) --- ### 4. Part Number Breakdown: M24C16-RBN6TP | Code Segment | Meaning | | :--- | :--- | | **M24** | I²C Serial Access EEPROM | | **C16** | 16 Kbit capacity | | **-R** | Operating Voltage: 1.8V to 5.5V | | **BN** | Package: PDIP8 (Plastic Dual In-line) | | **6** | Temperature Grade: Industrial (-40°C to 85°C) | | **TP** | Tape & Reel Packing (though BN usually implies Tube) | --- ### 5. Common Applications * **Device Configuration:** Storing MAC addresses, serial numbers, or calibration data. * **User Settings:** Saving volume levels, brightness, or last-used states in appliances. * **Data Logging:** Storing small amounts of sensor data over time. ---
