The **M24C02-RBN6TP/G** is a specific variant of the standard 2-Kbit serial I²C Bus EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by STMicroelectronics. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Memory Size** | 2 Kbit (256 x 8 bits) | | **Interface** | I²C (Inter-Integrated Circuit) | | **Operating Voltage (Vcc)** | 1.8V to 5.5V | | **Clock Frequency** | 400 kHz (Fast Mode) / 100 kHz (Standard) | | **Write Cycle Time** | 5 ms (Max) | | **Package Type** | PDIP8 (Plastic Dual In-line Package) | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Pin Configuration (PDIP8) The device typically follows the standard 8-pin EEPROM pinout: 1. **E0, E1, E2 (Pins 1-3):** Chip Enable inputs. Used to set the hardware address of the device, allowing up to 8 devices on the same I²C bus. 2. **Vss (Pin 4):** Ground. 3. **SDA (Pin 5):** Serial Data (Bidirectional). 4. **SCL (Pin 6):** Serial Clock. 5. **WC (Pin 7):** Write Control. If connected to Vcc, write operations are inhibited (Read-only mode). If connected to Vss, write operations are enabled. 6. **Vcc (Pin 8):** Power Supply. --- ### 3. Detailed Part Number Breakdown Understanding the suffix helps in identifying the specific physical and chemical properties of the component: * **M24C02**: Base series (I²C EEPROM, 2 Kbit). * **-R**: Indicates the voltage range (1.8V to 5.5V). * **BN**: Refers to the **PDIP8** package (Plastic Dual In-line). * **6**: Operating temperature range (Industrial: -40°C to +85°C). * **TP**: Tape & Reel packing (though BN/PDIP is usually bulk/tube, TP suggests specific packaging or Tape/Ammo). * **G**: Indicates **ECOPACK2** (RoHS compliant, Halogen-free, and lead-free). --- ### 4. Application and Usage This chip is primarily used for non-volatile storage of small amounts of data that must be preserved when power is removed, such as: * **Configuration Settings:** Storing user preferences or calibration data. * **Device Identification:** Storing serial numbers or MAC addresses. * **Counter Storage:** Maintaining state information in consumer electronics. ---
