The **M24C02-RMB6TG/G** is a specific variant of a standard 2-Kbit serial EEPROM (Electrically Erasable Programmable Memory). It is manufactured by **STMicroelectronics** and is widely used for storing small amounts of configuration data, parameters, or ID information in electronic circuits. --- ## 1. Technical Specifications The table below highlights the core electrical and physical characteristics of this component. | Parameter | Specification | | :--- | :--- | | **Memory Size** | 2 Kbit (256 bytes x 8 bits) | | **Interface** | I²C (Two-Wire Serial) | | **Operating Voltage (Vcc)** | 1.8V to 5.5V | | **Clock Frequency** | 400 kHz (Fast Mode), 1 MHz (Fast Mode Plus) | | **Package Type** | UFDFPN8 (Ultra-thin Fine pitch Dual Flat No-lead) | | **Operating Temperature** | -40°C to +85°C | | **Data Retention** | 40 Years | | **Write Endurance** | 4 Million Write Cycles | --- ## 2. Key Electronic Features ### A. I²C Serial Interface It utilizes a simple two-wire protocol consisting of **SCL** (Serial Clock) and **SDA** (Serial Data). This minimizes the number of pins required on the host microcontroller (MCU). ### B. Device Addressing The device has hardware pins (E0, E1, E2) that allow you to set a unique address. This enables up to **eight** M24C02 devices to be connected to the same I²C bus without conflict. ### C. Write Protection (WC) The **Write Control (WC)** pin is a hardware protection feature: * If connected to **Vcc**, the memory is write-protected (read-only). * If connected to **Vss (GND)**, write operations are enabled. ### D. Page Write Mode While you can write a single byte at a time, the device supports a **16-byte Page Write** mode. This allows the MCU to send up to 16 bytes in one operation, significantly improving data throughput. --- ## 3. Package and Ordering Code Breakdown The suffix **RMB6TG/G** provides specific information about the physical form factor and environmental standards: * **M24C02**: Base Part Number (2 Kbit EEPROM). * **-R**: Operating voltage range (1.8V to 5.5V). * **MB**: Package type (UFDFPN8 - 2x3 mm). * **6**: Industrial temperature range (-40°C to 85°C). * **TG**: Tape and Reel packaging. * **/G**: "Green" compliant (Halogen-free and RoHS compliant). --- ## 4. Typical Application Circuit When integrating this part into a circuit, pull-up resistors are required on the SDA and SCL lines. ```text Vcc (1.8V - 5.5V) | [10k Ohm Pull-ups] | | MCU SDA --------+------- SDA (Pin 5) MCU SCL ---------------- SCL (Pin 6) GND -------------------- Vss (Pin 4) Vcc -------------------- Vcc (Pin 8) ``` ---
