The **M95010-RBN6TP** is a specific type of Non-Volatile Memory (NVM) produced by STMicroelectronics. It is an Electrically Erasable Programmable Read-Only Memory (**EEPROM**) commonly used for parameter storage in electronic circuits. --- ## 1. Technical Specifications The following table outlines the primary electrical and physical characteristics of the device: | Parameter | Detail | | :--- | :--- | | **Memory Size** | 1 Kbit (128 Bytes x 8 bits) | | **Interface** | SPI (Serial Peripheral Interface) | | **Clock Frequency** | Up to 20 MHz (at 5V) | | **Operating Voltage** | 1.8V to 5.5V | | **Package Type** | SO8N (Narrow Plastic Small Outline, 8 pins) | | **Temperature Range** | -40°C to +85°C (Industrial Grade) | | **Write Cycles** | 4 Million cycles (approx.) | | **Data Retention** | 200 Years | --- ## 2. Key Electronic Features * **SPI Protocol:** It supports Mode 0 (0,0) and Mode 3 (1,1). It uses four signals: Chip Select ($\bar{S}$), Serial Clock (C), Serial Data Input (D), and Serial Data Output (Q). * **Byte and Page Write:** It allows for writing a single byte or a full page (up to 16 bytes) in a single instruction. * **Hardware Protection:** Includes a Write Protect ($\bar{W}$) pin to prevent accidental data overwrites and a Hold ($\bar{HOLD}$) pin to pause communication without deselecting the device. * **Low Power Consumption:** Optimized for battery-operated devices with low standby and active current. --- ## 3. Part Number Breakdown Understanding the suffix `RBN6TP` is critical for sourcing the correct part: 1. **M95010:** Base part number (1 Kbit SPI EEPROM). 2. **R:** Operating voltage range (1.8V to 5.5V). 3. **BN:** Package code for SO8N (150 mil width). 4. **6:** Device grade (Industrial temperature, -40 to 85°C). 5. **T/P:** Packing information (Tape and Reel / Lead-free and RoHS compliant). --- ## 4.
