The **M24C02-RBN6TP/S** is a specific variant of a standard 2-Kbit serial I2C EEPROM (Electrically Erasable Programmable Read-Only Memory). It is widely used in consumer electronics, industrial sensors, and medical devices for storing configuration data or small parameters. --- ### 1. Key Technical Specifications The table below outlines the core electronic characteristics of this specific component: | Feature | Specification | | :--- | :--- | | **Memory Size** | 2 Kbits (256 bytes organized as 256 x 8-bit) | | **Interface** | I2C (Serial 2-Wire) | | **Operating Voltage** | 1.8V to 5.5V | | **Clock Frequency** | 400 kHz (Fast Mode) / 100 kHz (Standard Mode) | | **Write Cycle Time** | 5 ms (Maximum) | | **Endurance** | 4 Million write cycles (typical) | | **Data Retention** | 200 Years | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Part Number Breakdown The suffixing of the part number reveals its physical and electrical properties: * **M24C02**: Base series (I2C EEPROM, 2 Kbit). * **-R**: Operating voltage range (1.8V to 5.5V). * **B**: Internal device code/process technology. * **N**: Package type (**PDIP8** - Plastic Dual In-line Package, 8 pins). * **6**: Temperature range (-40°C to +85°C). * **TP/S**: Tape and Reel packaging with specific production plant or plating coding. --- ### 3. Pin Configuration (PDIP8) | Pin Number | Name | Description | | :--- | :--- | :--- | | 1, 2, 3 | E0, E1, E2 | Chip Enable inputs (used to set the device I2C address). | | 4 | VSS | Ground. | | 5 | SDA | Serial Data (bidirectional). | | 6 | SCL | Serial Clock (input). | | 7 | WC | Write Control (Hardware protection; pull high to prevent writing). | | 8 | VCC | Supply Voltage. | --- ### 4. Implementation Example To interface this chip with a microcontroller (like an Arduino or STM32), pull-up resistors are required on the SDA and SCL lines. ```cpp // Example: Basic I2C Address calculation // Address format: 1 0 1 0 E2 E1 E0 R/W // If E0, E1, and E2 are connected to Ground: #define EEPROM_I2C_ADDRESS 0x50 // Example Write function logic void writeEEPROM(int address, byte data) { Wire.beginTransmission(EEPROM_I2C_ADDRESS); Wire.write(address); // Memory location (0-255) Wire.write(data); // Data byte Wire.endTransmission(); delay(5); // Mandatory 5ms write cycle delay } ``` --- ### 5. Key Features & Protections * **Byte and Page Write**: Supports writing a single byte or a page of up to 16 bytes. * **Write Protection**: The **WC** pin provides hardware data protection. If tied to VCC, the memory becomes read-only, protecting firmware settings from accidental corruption. * **Schmitt Triggers**: Inputs are filtered for noise suppression, which is critical in industrial environments.
