## M24C01-RDS6TG/G Technical Overview The **M24C01-RDS6TG/G** is a specific variant of the M24C01 family of Serial I²C Bus EEPROMs (Electrically Erasable Programmable Read-Only Memory) manufactured by **STMicroelectronics**. This component is commonly used for storing configuration data, user settings, or calibration constants in space-constrained electronic designs. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Memory Size** | 1 Kbit (128 bytes x 8 bits) | | **Interface** | I²C (Inter-Integrated Circuit) | | **Clock Frequency** | 400 kHz (Fast Mode) | | **Supply Voltage (Vcc)** | 1.8V to 5.5V | | **Package Type** | TSSOP8 (Thin Shrink Small Outline Package) | | **Operating Temp Range** | -40°C to +85°C (Industrial Grade) | | **Write Cycles** | 4 Million cycles (Typical) | | **Data Retention** | 200 Years | --- ### 2. Part Number Breakdown The suffixing provides specific information about the physical and logistical properties of the chip: * **M24C01**: Base Part Number (1 Kbit I²C EEPROM). * **-R**: Operating voltage range (1.8V to 5.5V). * **DS**: TSSOP8 package (3x4.4 mm body). * **6**: Device grade (Industrial temperature range -40°C to 85°C). * **T**: Tape & Reel packaging. * **G / G**: ECOPACK2 (RoHS compliant / Lead-free / Halogen-free). --- ### 3. Pin Configuration (TSSOP8) ```text TSSOP8 Pinout +-----+--+-----+ E0 | 1 +--+ 8 | Vcc E1 | 2 | 7 | WC (Write Control) E2 | 3 | 6 | SCL (Serial Clock) Vss | 4 | 5 | SDA (Serial Data) +--------------+ ``` * **E0, E1, E2**: Chip Enable inputs. These are used to set the hardware address of the device, allowing up to 8 similar devices on the same I²C bus. * **SDA/SCL**: The standard I²C data and clock lines. * **WC (Write Control)**: A hardware protection pin. When connected to Vcc, write operations are inhibited (read-only mode). When connected to Vss (Ground), the full memory is writable. * **Vcc/Vss**: Power supply and ground pins. --- ### 4. Functional Features * **Byte and Page Write**: Supports writing a single byte or a page of up to 16 bytes. * **Random and Sequential Read**: Data can be read starting from a specific address or sequentially through the entire memory map. * **Schmitt Trigger Inputs**: Integrated into the SDA and SCL lines for noise filtering. * **Low Power Consumption**: Consumes very little current (typically 1 µA in Standby mode), making it ideal for battery-powered devices.
