## M24C01-RBN6TG: Electronic Component Overview The **M24C01-RBN6TG** is a 1-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 compact electronic devices. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Memory Size** | 1 Kbit (128 x 8 bits) | | **Interface** | I²C Serial (Two-Wire) | | **Operating Voltage** | 1.8V to 5.5V | | **Clock Frequency** | 400 kHz | | **Package Type** | PDIP8, SO8, TSSOP8 (BN6 indicates PDIP8) | | **Operating Temp** | -40°C to +85°C | | **Write Cycles** | 1 Million cycles | | **Data Retention** | 40 Years | --- ### 2. Functional Pinout Description The device typically follows a standard 8-pin layout. Below are the functions of each pin: 1. **E0, E1, E2 (Chip Enable):** These pins are used to set the hardware address of the device. This allows multiple EEPROMs to be connected to the same I²C bus. 2. **VSS:** Ground reference. 3. **SDA (Serial Data):** The bidirectional pin used to transfer data in and out of the device. 4. **SCL (Serial Clock):** The input pin used to synchronize all data transfers. 5. **WC (Write Control):** A hardware protection pin. If connected to $V_{CC}$, write operations are inhibited (Read-only mode). If connected to $V_{SS}$, write operations are enabled. 6. **VCC:** Supply voltage. --- ### 3. Core Features * **Byte and Page Write:** Supports writing a single byte or a page of up to 16 bytes. * **Low Power Consumption:** Designed for battery-operated devices, with very low active and standby currents. * **Random and Sequential Read:** Allows the processor to read data from a specific address or stream data sequentially from the memory array. * **Self-Timed Write Cycle:** The device handles the internal timing for erasing and writing data, usually completing in under 5ms. --- ### 4.
