## Overview of M24C04-RMB6TP The **M24C04-RMB6TP** is a 4-Kbit serial I²C (Inter-Integrated Circuit) EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by **STMicroelectronics**. It is designed for low-power, low-voltage applications where non-volatile storage is required for configuration data or small logs. --- ### Technical Specifications Below are the primary electrical and physical characteristics: | Feature | Specification | | :--- | :--- | | **Memory Size** | 4 Kbit (512 bytes) | | **Organization** | 512 x 8 bits | | **Interface** | I²C Serial (2-wire) | | **Operating Voltage (Vcc)** | 1.8V to 5.5V | | **Clock Frequency** | 400 kHz (Fast Mode) | | **Package Type** | UFDFPN8 (Ultra-thin Fine pitch Dual Flat No-lead) | | **Temperature Range** | -40°C to +85°C | | **Write Cycles** | 4 million cycles (per byte) | | **Data Retention** | 200 years | --- ### Pin Configuration (UFDFPN8) The device typically uses an 8-pin layout. The specific pin functions are outlined below: 1. **E1, E2:** Address inputs used to define the device address on the I²C bus. (Note: On 4Kbit models, E0 is often not used or internal). 2. **Vss:** Ground connection. 3. **SDA:** Serial Data (Bidirectional). 4. **SCL:** Serial Clock. 5. **WC:** Write Control. If connected to Vcc, the memory is write-protected. If connected to Vss, write operations are enabled. 6. **Vcc:** Power supply. --- ### Core Functional Features * **Byte and Page Write:** Supports writing a single byte or a full page (up to 16 bytes) in a single cycle. * **Random and Sequential Read:** Allows reading data from any specific address or reading the entire memory sequentially. * **Low Power Consumption:** * Active Read Current: < 1 mA * Standby Current: < 1 µA (at 1.8V) * **Internal Write Cycle:** Self-timed write cycle that typically completes in 5ms. * **ESD Protection:** High Electrostatic Discharge protection (up to 4000V). --- ### Application Usage This specific part is frequently used in mobile devices, consumer electronics, and industrial sensors for: * Storing calibration constants. * Storing user preferences and settings. * Device identification codes. * Error logging in battery-powered systems. ---
