## M24C01-RDS6T: Technical Overview The **M24C01-RDS6T** is a specific variant of the M24C01 series manufactured by **STMicroelectronics**. It is a 1-Kbit serial I²C (Inter-Integrated Circuit) EEPROM (Electrically Erasable Programmable Memory). --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Memory Size** | 1 Kbit (128 x 8 bits) | | **Interface** | I²C Serial (2-wire) | | **Operating Voltage** | 1.8V to 5.5V | | **Clock Frequency** | Up to 400 kHz (Fast Mode) | | **Package Type** | TSSOP8 (Thin Shrink Small Outline Package) | | **Temperature Range** | -40°C to +85°C (Industrial Grade) | | **Write Cycles** | More than 4 million cycles | | **Data Retention** | Over 200 years | --- ### 2. Detailed Part Number Breakdown The suffix **RDS6T** provides specific details about the component's packaging and thermal characteristics: * **M24C01**: Base part number (1 Kbit I²C EEPROM). * **R**: Operating voltage range (1.8V to 5.5V). * **D**: Device revision or specific process technology. * **S**: Package type (TSSOP8, 169 mil width). * **6**: Temperature range (-40°C to +85°C). * **T**: Tape and Reel packaging (used for automated assembly). --- ### 3. Pin Configuration (TSSOP8) | Pin Number | Name | Description | | :--- | :--- | :--- | | 1, 2, 3 | E0, E1, E2 | Chip Enable inputs (used to address multiple devices on the same bus). | | 4 | VSS | Ground. | | 5 | SDA | Serial Data (bidirectional). | | 6 | SCL | Serial Clock. | | 7 | WC | Write Control (Hardware protection). | | 8 | VCC | Supply Voltage. | --- ### 4. Functional Features * **Byte and Page Write**: Supports writing a single byte or a page of up to 16 bytes. * **Hardware Write Protection**: The **WC** pin can be tied to $V_{CC}$ to protect the entire memory contents from being overwritten. * **Low Power Consumption**: Designed for battery-operated devices with low active and standby currents. * **I²C Protocol**: Operates as a slave device on the bus, requiring a start condition, device address, memory address, and data. --- ### 5. Common Applications * **Parameter Storage**: Storing calibration data, user preferences, or configuration settings. * **Identification**: Storing serial numbers or MAC addresses. * **Consumer Electronics**: Used in TVs, remote controls, and medical devices.
