The **M24C16-RMB6TG** is a specific variant of the M24C16 series, which is an I²C-compatible Electrically Erasable Programmable Read-Only Memory (EEPROM). It is manufactured by **STMicroelectronics**. Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ### 1. Key Technical Specifications The "M24C16-RMB6TG" part number identifies specific parameters such as density, voltage range, and package type. | Feature | Specification | | :--- | :--- | | **Memory Size** | 16 Kbit (2048 x 8 bits) | | **Interface** | I²C (Inter-Integrated Circuit) | | **Clock Frequency** | 400 kHz (Fast Mode) / 100 kHz (Standard Mode) | | **Supply Voltage (Vcc)** | 1.8V to 5.5V (Wide Range) | | **Write Cycle Time** | 5 ms (Maximum) | | **Endurance** | 4 Million Write Cycles | | **Data Retention** | 200 Years | | **Package** | UFDFPN8 (Ultra-thin Fine pitch Dual Flat No-lead) | --- ### 2. Part Number Breakdown Understanding the suffix is critical for identifying the physical and electrical constraints of the chip: * **M24**: I²C family of EEPROMs. * **C16**: 16 Kbit density. * **-R**: Operates at a voltage range of 1.8V to 5.5V. * **MB**: UFDFPN8 package (2x3 mm size). * **6**: Industrial temperature range (-40°C to +85°C). * **T**: Tape and Reel packaging. * **G**: ECOPACK2 (RoHS compliant/Halogen-free). --- ### 3. Pin Configuration (UFDFPN8) The device typically uses 8 pins, though in the 16Kbit version, some addressing pins are used differently than in smaller densities. | Pin | Name | Description | | :--- | :--- | :--- | | 1-3 | NC / E | Not Connected or Chip Enable (used for hardware addressing). | | 4 | Vss | Ground. | | 5 | SDA | Serial Data (Bi-directional). | | 6 | SCL | Serial Clock (Input). | | 7 | WC | Write Control (Hardware protection). | | 8 | Vcc | Supply Voltage. | --- ### 4. Functional Features #### A. Write Protection (WC Pin) The **WC (Write Control)** pin is a hardware safety feature. - If connected to **Vcc**, the entire memory is write-protected (read-only). - If connected to **Vss (Ground)**, the memory can be written to. #### B. Page Write Buffer The device supports a **16-byte page write**. This allows you to write up to 16 contiguous bytes in a single bus cycle, significantly improving write speeds compared to byte-by-byte programming. #### C. Device Addressing Since the M24C16 has 16 Kbits, it requires 11 bits of internal addressing. In the I²C protocol, the 3 least significant bits of the "Device Select" code are used as the most significant bits of the memory address. This means the device occupies all 8 possible addresses on an I²C bus (0xA0 through 0xAE). --- ### 5. Typical Applications * **Consumer Electronics:** Storing user settings, calibration data, or volume levels. * **Industrial:** Storing serial numbers, configuration parameters, and error logs. * **Medical:** Storing patient IDs or device usage history.
