The **M24C02-RMB6TP/G** is a specific variant of an I2C-compatible Electrically Erasable Programmable Read-Only Memory (EEPROM). It is manufactured by **STMicroelectronics** and is widely used for storing small amounts of non-volatile configuration data. --- ## 1. Key Technical Specifications | Parameter | Specification | |:---|:---| | **Memory Size** | 2 Kbit (256 x 8 bits) | | **Interface** | I2C (Inter-Integrated Circuit) | | **Clock Frequency** | 400 kHz (Fast Mode) / 100 kHz (Standard) | | **Operating Voltage** | 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 (typical) | | **Data Retention** | 200 Years | --- ## 2. Pin Configuration (UFDFPN8) The device features 8 pins, typically mapped as follows for the I2C protocol: 1. **E0, E1, E2:** Chip Enable inputs (used to define the I2C device address). 2. **VSS:** Ground. 3. **SDA:** Serial Data (bidirectional). 4. **SCL:** Serial Clock. 5. **WC:** Write Control (Hardware protection; if connected to VCC, write operations are inhibited). 6. **VCC:** Supply Voltage. --- ## 3. Core Functionalities ### Memory Architecture The memory is organized as **256 bytes**. Because it is I2C-based, it uses a 7-bit device address. The first 4 bits are fixed (`1010`), and the next 3 bits are defined by the hardware state of pins E0, E1, and E2. ### Write Operations * **Byte Write:** Writing a single 8-bit byte to a specific address. * **Page Write:** Allows writing up to **16 bytes** in a single instruction cycle, provided they are within the same page boundary. ### Low Power Features The "R" in the part number indicates a wide voltage range (1.8V - 5.5V), making it ideal for battery-powered mobile devices. It enters a "Wait" state automatically after a write cycle to conserve energy. --- ## 4.
