## Overview of the M24C01-RDS6TG The **M24C01-RDS6TG** is a 1-Kbit serial I2C bus EEPROM (Electrically Erasable Programmable Memory) manufactured by STMicroelectronics. It is designed for low-power and low-voltage applications, commonly used to store configuration data, calibration parameters, or small amounts of user data. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Memory Size** | 1 Kbit (128 bytes × 8 bits) | | **Interface** | I2C (Serial 2-Wire) | | **Operating Voltage** | 1.8V to 5.5V | | **Clock Frequency** | 400 kHz (Fast Mode) | | **Package Type** | TSSOP8 (Thin Shrink Small Outline Package) | | **Operating Temperature** | -40°C to +85°C | | **Write Cycles** | More than 4 million cycles | | **Data Retention** | More than 200 years | --- ### 2. Pin Configuration (TSSOP8) The device typically utilizes 8 pins, though not all are always used for data transfer: * **E0, E1, E2:** Chip Enable inputs. These are used to set the hardware address of the device on the I2C bus, allowing multiple EEPROMs to be connected to the same lines. * **SDA (Serial Data):** Bi-directional pin used to transfer addresses and data into and out of the device. * **SCL (Serial Clock):** Input used to synchronize the data transfer. * **WC (Write Control):** A hardware write-protection pin. If tied to $V_{CC}$, write operations are inhibited. If tied to $V_{SS}$ (Ground), write operations are enabled. * **VCC / VSS:** Power supply and Ground. --- ### 3. Core Functional Features #### Byte and Page Write The device supports both **Byte Write** (writing 1 byte at a time) and **Page Write** (up to 8 bytes in a single write cycle). This improves efficiency when updating larger chunks of data. #### Low Power Consumption Designed for battery-operated devices, it features: * **Active Read Current:** < 1 mA * **Standby Current:** < 1 µA (at 1.8V) #### Data Protection The **WC (Write Control)** pin provides physical protection against accidental data overwrites, which is critical for storing firmware settings or security keys. --- ### 4.
