The **M24C02-RCT6TP/S** is a specific variant of the widely used 2-Kbit serial I2C Bus EEPROM (Electrically Erasable Programmable Read-Only Memory). It is manufactured by STMicroelectronics. --- ## 1. Technical Specifications The following table highlights the core electronic characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Memory Size** | 2 Kbit (256 bytes x 8 bits) | | **Interface** | I2C (Inter-Integrated Circuit) | | **Clock Frequency** | 400 kHz (Fast Mode) | | **Operating Voltage** | 1.8V to 5.5V | | **Operating Temperature** | -40°C to +85°C | | **Package Type** | TSSOP8 (Thin Shrink Small Outline Package) | | **Write Cycles** | 4 Million (Minimum) | | **Data Retention** | 200 Years | --- ## 2. Pin Configuration The M24C02-RCT6TP/S typically uses an 8-pin layout. Below is the functional description for each pin: 1. **E0, E1, E2 (Chip Enable):** These pins are used to set the hardware address for the device. You can connect up to 8 similar devices on the same I2C bus. 2. **VSS:** Ground connection. 3. **SDA (Serial Data):** The bidirectional pin used to transfer data into 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 $V_{SS}$, the device is fully writable. 6. **VCC:** Power supply. --- ## 3. Key Electronic Features ### A. I2C Protocol Support The device acts as a **Slave** on the I2C bus. It supports: * **Byte Write:** Writing a single 8-bit byte. * **Page Write:** Writing up to 16 bytes in a single write cycle, improving efficiency. * **Random/Sequential Read:** Flexibility in accessing data addresses. ### B. Low Power Consumption Designed for battery-operated devices, it features a very low supply current: * **Active Read Current:** < 1 mA * **Standby Current:** < 1 µA (at 1.8V) ### C. Enhanced Write Protection The `WC` (Write Control) pin provides hardware-level security against accidental data corruption, which is critical for storing configuration settings or calibration data. --- ## 4. Part Number Breakdown Understanding the specific suffix `/S` and `TP`: * **M24C02:** 2 Kbit Capacity. * **R:** Operating Voltage Range (1.8V to 5.5V). * **C:** TSSOP8 Package. * **T:** Tape and Reel packaging. * **6:** Industrial temperature range (-40 to +85°C). * **TP:** Process technology (standard for ST). * **S:** Often indicates a specific manufacturing site or a slight revision in the internal circuitry for specialized reliability. ---
