## Electronic Overview of M95320-RDL6P The **M95320-RDL6P** is a high-performance, electrically erasable programmable memory (EEPROM) manufactured by **STMicroelectronics**. It is organized as 4096 x 8 bits (32 Kbit) and is accessed via a high-speed SPI (Serial Peripheral Interface) bus. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Memory Size** | 32 Kbit (4 Kbytes) | | **Interface** | SPI (Serial Peripheral Interface) | | **Supply Voltage (Vcc)** | 1.8V to 5.5V | | **Max Clock Frequency** | 5 MHz (at 1.8V) to 20 MHz (at 4.5V+) | | **Package Type** | MLP / DFN8 (2x3 mm) | | **Operating Temperature** | -40°C to +85°C | | **Endurance** | 4 Million Write Cycles | | **Data Retention** | 200 Years | --- ### 2. Pinout Configuration The "L6P" suffix typically refers to a small form-factor package like the **UFDFPN8** (MLP8). The standard pin functions are as follows: | Pin | Name | Description | | :--- | :--- | :--- | | 1 | **S#** | Chip Select (Active Low) | | 2 | **Q** | Serial Data Output | | 3 | **W#** | Write Control / Protect | | 4 | **Vss** | Ground | | 5 | **D** | Serial Data Input | | 6 | **C** | Serial Clock | | 7 | **HOLD#** | Pause Serial Communication | | 8 | **Vcc** | Supply Voltage | --- ### 3. Core Features * **Byte and Page Write:** Supports writing a single byte or a page of up to 32 bytes in one cycle. * **Write Protection:** Includes a status register that allows the user to software-protect blocks of memory (Quarter, Half, or Entire memory array). * **High Reliability:** Designed for applications requiring frequent data logging and long-term storage without power. * **Low Power Consumption:** Optimized for battery-operated devices with low standby current. --- ### 4.
