## M24C08-RBN6TP: Electronic Specifications and Overview The **M24C08-RBN6TP** is a specific variant of the M24C08 series, which is a 8-Kbit serial I²C (Inter-Integrated Circuit) Electrically Erasable Programmable Read-Only Memory (**EEPROM**). It is manufactured by STMicroelectronics. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Memory Size** | 8 Kbit (1024 x 8 bits) | | **Memory Type** | Non-volatile EEPROM | | **Interface** | I²C Serial (2-wire) | | **Operating Voltage ($V_{CC}$)** | 1.8V to 5.5V | | **Clock Frequency** | 400 kHz (Fast Mode) | | **Package Type** | PDIP8 (Plastic Dual In-line Package) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Write Cycles** | 4 million cycles (typical) | | **Data Retention** | 200 years | --- ### 2. Detailed Pinout and Functions The M24C08 usually comes in an 8-pin configuration. Below is the functional mapping for the **RBN6TP** (PDIP) variant: | Pin Number | Name | Type | Description | | :--- | :--- | :--- | :--- | | 1, 2, 3 | E0, E1, E2 | Input | **Chip Enable:** Used to set the device address (Note: M24C08 ignores E0 and E1 as they are used for internal page addressing). | | 4 | $V_{SS}$ | Ground | Reference ground. | | 5 | SDA | I/O | **Serial Data:** Bidirectional pin for data transfer. | | 6 | SCL | Input | **Serial Clock:** Provides the clock signal for synchronization. | | 7 | WC | Input | **Write Control:** Hardware protection. If tied to $V_{CC}$, writes are disabled. | | 8 | $V_{CC}$ | Power | Supply voltage. | --- ### 3. Core Features * **Page Write Mode:** Allows writing up to 16 bytes in a single write cycle, improving efficiency for large data sets. * **Byte Write:** Allows modification of individual bytes. * **Hardware Write Protection:** The `WC` pin provides a way to protect the entire memory against accidental write operations. * **Low Power Consumption:** * Active Read Current: < 1 mA * Standby Current: < 1 µA (at 1.8V) * **Compatibility:** Fully compatible with all I²C bus modes (100kHz and 400kHz). --- ### 4. Part Number Breakdown (M24C08-RBN6TP) Understanding the suffix helps identify the specific physical characteristics: * **M24**: I²C family of EEPROMs. * **C08**: 8 Kbit density. * **-R**: Operating voltage range of 1.8V to 5.5V. * **BN**: PDIP8 package (Plastic Dual In-line). * **6**: Industrial temperature range (-40°C to 85°C). * **TP**: Tape and Reel packaging (standard for automated assembly). --- ### 5. Application Circuit Example To integrate this part, you typically need two pull-up resistors on the **SDA** and **SCL** lines (usually $4.7k\Omega$ to $10k\Omega$). ```c // Example Pseudocode for Initialization void init_eeprom() { I2C_Start(); I2C_SendAddress(0xA0); // Default 7-bit address + Write bit // Further logic to read/write data... } ```
