The **M24C04-RMB6TP/G** is a specific variant of an I²C Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by **STMicroelectronics**. It is widely used for parameter storage in consumer electronics and industrial applications. --- ## 1. Technical Specifications The following table outlines the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Memory Size** | 4 Kbit (512 bytes) | | **Organization** | 512 x 8 bits | | **Interface** | I²C (Inter-Integrated Circuit) | | **Clock Frequency** | 400 kHz (Fast Mode) / 100 kHz (Standard) | | **Supply Voltage (Vcc)** | 1.8V to 5.5V | | **Package Type** | UFDFPN8 (Ultra-thin Fine pitch Dual Flat No-lead) | | **Operating Temp** | -40°C to +85°C | | **Write Cycles** | 4 million cycles | | **Data Retention** | 200 Years | --- ## 2. Pinout Configuration The device usually comes in an 8-pin package. Below is the typical pin mapping: 1. **E1, E2**: Chip Enable inputs (used to set the device address). 2. **Vss**: Ground. 3. **SDA**: Serial Data (bi-directional). 4. **SCL**: Serial Clock. 5. **WC**: Write Control (Hardware write protection). 6. **Vcc**: Supply Voltage. 7. **NC**: No internal connection. --- ## 3. Part Number Breakdown The suffix code provides details on the specific packaging and environmental standards: * **M24C04**: Base model (4 Kbit I²C EEPROM). * **-R**: Range of supply voltage (1.8V to 5.5V). * **MB**: Package code (UFDFPN8). * **6**: Temperature range (-40 to 85 °C). * **T**: Tape and Reel packing. * **P/G**: ECOPACK2 (RoHS compliant, Halogen-free). --- ## 4. Key Features * **Byte and Page Write**: Supports writing a single byte or a page of up to 16 bytes. * **Random and Sequential Read**: Allows reading data from any address or reading the entire memory sequentially. * **Hardware Write Protection**: When the `WC` pin is held High, the entire memory becomes read-only, preventing accidental data corruption. * **Low Power Consumption**: Consumes very little current in standby mode (typically < 1 µA), making it ideal for battery-powered devices. ---
