## Technical Overview of M24C02-RDS3TP/G The **M24C02-RDS3TP/G** is a specific variant of the 2-Kbit serial I²C Bus 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** | 2 Kbit (256 bytes) | | **Interface** | I²C (Two-wire Serial) | | **Supply Voltage (Vcc)** | 1.8V to 5.5V | | **Clock Frequency** | 400 kHz (Fast Mode) / 100 kHz (Standard) | | **Package Type** | TSSOP8 (Thin Shrink Small Outline Package) | | **Temperature Range** | -40°C to +125°C (Grade 3) | | **Endurance** | 4 million write cycles | | **Data Retention** | 200 years | --- ### 2. Pin Configuration (TSSOP8) The device features 8 pins, structured as follows: | Pin Number | Name | Description | | :--- | :--- | :--- | | 1, 2, 3 | E0, E1, E2 | Chip Enable inputs (used to set the device address). | | 4 | Vss | Ground. | | 5 | SDA | Serial Data (bi-directional). | | 6 | SCL | Serial Clock. | | 7 | WC | Write Control (Hardware Write Protection). | | 8 | Vcc | Supply Voltage. | --- ### 3. Core Functional Electronic Features #### A. I²C Serial Interface The device operates as a **Slave** on the I²C bus. It uses a 7-bit device addressing scheme. With three Chip Enable pins (E0, E1, E2), up to eight M24C02 devices can be connected to the same I²C bus. #### B. Memory Organization The 2048 bits are organized as **256 words of 8 bits each**. It supports both **Byte Write** and **Page Write** (up to 16 bytes at a time), which improves efficiency during large data transfers. #### C. Hardware Write Protection (WC Pin) * If **WC** is high (connected to Vcc), the entire memory is write-protected. * If **WC** is low (connected to Vss), the memory can be modified. #### D. Enhanced Reliability The "/G" suffix in the part number usually refers to a specific manufacturing process or an ECOPACK® grade, ensuring the part is **Halogen-free and RoHS compliant**. The high endurance (4M cycles) makes it suitable for frequently updated parameters. --- ### 4.
