## M24C01-RMB6TP: Electronic Specifications and Overview The **M24C01-RMB6TP** is a 1-Kbit serial I²C (Inter-Integrated Circuit) EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by **STMicroelectronics**. It is designed for low-power and low-voltage applications. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Memory Size** | 1 Kbit (128 bytes x 8 bits) | | **Interface** | I²C Serial (Two-Wire) | | **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) | | **Operating Temperature** | -40°C to +85°C | | **Write Cycles** | More than 4 million cycles | | **Data Retention** | More than 200 years | --- ### 2. Functional Description The device operates as a slave in the I²C protocol. It is used to store small amounts of non-volatile data that must be preserved even when power is removed. #### Memory Architecture * **1 Kbit Total:** Organized as 128 bytes of 8 bits each. * **Page Write:** Supports writing up to 8 bytes in a single write cycle. * **Write Time:** A self-timed write cycle typically takes **5 ms**. #### Pin Configuration (UFDFPN8) 1. **E0, E1, E2:** Chip Enable inputs (used to define the device address on the I²C bus). 2. **VSS:** Ground. 3. **SDA:** Serial Data (Bi-directional). 4. **SCL:** Serial Clock. 5. **WC:** Write Control (Hardware protection; if tied to $V_{CC}$, write operations are inhibited). 6. **VCC:** Supply Voltage. --- ### 3. Key Electronic Features * **Low Power Consumption:** * Active Read Current: < 1 mA * Standby Current: < 1 µA (at 1.8V) * **Schmitt Triggers:** Inputs are filtered for noise suppression to ensure stable communication in noisy environments. * **Enhanced Write Protection:** The **WC (Write Control)** pin provides hardware-level data security, preventing accidental overwrites of the memory. * **Byte and Page Write:** Flexibility to update a single byte or a block of 8 bytes simultaneously. --- ### 4. Typical Applications * **Consumer Electronics:** Storing configuration settings in cameras or wearables. * **Computing:** Storing SPD (Serial Presence Detect) data. * **Industrial:** Parameter storage for sensors and small controllers where space is limited. ---
