The **M24C02-RMB6TP** is a specific variant of the M24C02 series, which is a 2-Kbit serial I²C (Inter-Integrated Circuit) EEPROM (Electrically Erasable Programmable Read-Only Memory). It is widely used for storing small amounts of configuration data, calibration parameters, or device IDs. --- ### ## Technical Specifications Below are the primary electrical and physical characteristics of this specific part number: | Parameter | Specification | | :--- | :--- | | **Memory Size** | 2 Kbits (256 bytes) | | **Interface** | I²C Serial (2-wire) | | **Clock Frequency** | 400 kHz (Fast Mode) / 1 MHz (Fast Mode Plus) | | **Supply Voltage (Vcc)** | 1.8V to 5.5V | | **Package Type** | UFDFPN8 (Ultra-thin Fine pitch Dual Flat No-lead) | | **Temperature Range** | -40°C to +85°C | | **Write Cycles** | 4 million cycles (typical) | | **Data Retention** | 200 years | --- ### ### Key Features and Functionality 1. **Memory Organization**: The 2 Kbit memory is organized as **256 words of 8 bits each**. It is accessed as a single block of memory. 2. **Byte and Page Write**: It supports both single-byte writes and page writes. The page size for this device is **16 bytes**. 3. **Device Addressing**: It uses a standard 7-bit I²C address. The hardware pins (E2, E1, E0) allow up to eight M24C02 devices to be connected to the same I²C bus. 4. **Write Protection (WC)**: It features a Write Control (WC) pin. When tied to High, the memory becomes write-protected (read-only); when tied to Low, write operations are enabled. 5. **Low Power Consumption**: Designed for battery-operated devices, it features low active current and very low standby current. --- ### ### Decoding the Part Number The suffix `RMB6TP` provides specific information about the physical build and delivery: * **M24C02**: Base part number (2-Kbit EEPROM). * **-R**: Operating voltage range (1.8V to 5.5V). * **MB**: Package code for **UFDFPN8** (2x3 mm). * **6**: Industrial temperature range (-40°C to 85°C). * **TP**: Tape and Reel packaging. --- ### ### Typical Application Circuit In a standard circuit, the device connects to a microcontroller (MCU) as follows: ```cpp // Typical Pin Connection VCC --> 3.3V or 5V Power Supply VSS --> Ground SCL --> MCU I2C Clock (with pull-up resistor) SDA --> MCU I2C Data (with pull-up resistor) WC --> Ground (to enable writing) E0, E1, E2 --> Address selection (usually GND for address 0xA0) ```
