## Technical Overview: M24C01-RMB6T/G The **M24C01-RMB6T/G** is a specific variant of the M24C01 family of serial $I^2C$ EEPROM (Electrically Erasable Programmable Read-Only Memory) devices manufactured by **STMicroelectronics**. It is designed for low-power, non-volatile data storage applications. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Memory Size** | 1 Kbit (128 bytes x 8 bits) | | **Interface** | $I^2C$ (Inter-Integrated Circuit) | | **Supply Voltage ($V_{CC}$)** | 1.8V to 5.5V | | **Clock Frequency** | 400 kHz (Fast Mode) | | **Package Type** | UFDFPN8 (Ultra-thin Fine pitch Dual Flat No-lead) | | **Temperature Range** | -40°C to +85°C (Industrial Grade) | | **Write Cycles** | 4 Million (approximate) | | **Data Retention** | 200 Years | --- ### 2. Detailed Electronic Characteristics #### A. Memory Architecture * **Organization:** The memory is organized as 128 bytes of 8 bits each. * **Page Write:** It supports a page write buffer of up to **16 bytes**, allowing multiple bytes to be written in a single $I^2C$ write cycle to improve efficiency. #### B. $I^2C$ Communication Protocol * **Device Address:** The device uses a fixed 7-bit slave address. For the M24C01, the typical control byte is `1010` followed by chip enable bits. * **Bidirectional Data:** Uses two lines: **SDA** (Serial Data) and **SCL** (Serial Clock). * **Schmitt Trigger Inputs:** The inputs are equipped with Schmitt triggers for noise filtering to ensure stable data transmission. #### C. Power Management * **Ultra-Low Power:** It features a low operating current (typically less than 1 mA for read/write) and an extremely low standby current (around 1 $\mu$A). * **Write Protection:** Includes a **WP** (Write Control) pin. When connected to $V_{CC}$, it prevents any write operations to the memory, providing hardware-level data security. --- ### 3.
