The **M24C08-RMB3T/G** is a specific variant of an Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by **STMicroelectronics**. It belongs to the M24C08 family, which is widely used for non-volatile data storage in consumer electronics and industrial applications. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and functional characteristics of the M24C08-RMB3T/G: | Parameter | Specification | | :--- | :--- | | **Memory Size** | 8 Kbit (organized as 1024 x 8 bits) | | **Interface** | I²C (Inter-Integrated Circuit) | | **Supply Voltage (Vcc)** | 1.8V to 5.5V | | **Clock Frequency** | 400 kHz (Fast Mode) | | **Operating Temperature** | -40°C to +125°C | | **Data Retention** | 40 Years | | **Write Endurance** | 4 million write cycles | | **Package Type** | UFDFPN8 (Ultra-thin Fine pitch Dual Flat No-lead) | --- ### 2. Breakdown of the Part Number The part number follows a specific nomenclature used by STMicroelectronics: * **M24**: Refers to the I²C interface family. * **C08**: Indicates the capacity (8 Kbit). * **-R**: Indicates the low voltage range (1.8V to 5.5V). * **MB**: Specifies the package type (UFDFPN8). * **3**: Represents the temperature range (-40°C to +125°C). * **T/G**: Refers to Tape & Reel packaging and Green/RoHS compliance. --- ### 3. Pin Configuration and Functions The M24C08 typically utilizes 8 pins, even in its small form-factor package: 1. **E0, E1, E2**: Address inputs (used to define the device's I²C address, though in the 8K version, some are used internally for page addressing). 2. **SDA (Serial Data)**: Bidirectional pin used to transfer data in and out. 3. **SCL (Serial Clock)**: Input pin used to synchronize data transfers. 4. **WC (Write Control)**: A hardware protection pin. When connected to Vcc, write operations are inhibited. 5. **Vcc / Vss**: Power supply and Ground. --- ### 4. Core 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 a specific address or streaming data sequentially. * **Schmitt Trigger Inputs**: Used for noise filtering on the SCL and SDA lines to ensure signal integrity. * **Low Power Consumption**: Consumes very little current in standby mode (typically <1µA), making it ideal for battery-powered devices. ---
