## M95010-RBN6 Electronic Components Overview The **M95010-RBN6** is a low-voltage, serial Peripheral Interface (SPI) Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by STMicroelectronics. It is designed for high-reliability data storage in space-constrained applications. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Memory Size** | 1 Kbit (128 x 8 bits) | | **Interface** | SPI (Serial Peripheral Interface) | | **Operating Voltage** | 1.8V to 5.5V | | **Clock Frequency** | 5 MHz (at 1.8V) to 20 MHz (at 4.5V) | | **Package Type** | PDIP8, SO8, TSSOP8, or UFDFPN8 | | **Temperature Range** | -40°C to +85°C | | **Write Cycles** | 4,000,000 Cycles (Minimum) | | **Data Retention** | 200 Years | --- ### 2. Pin Configuration and Functions The device typically comes in an 8-pin package. Below are the functional descriptions of each pin: | Pin | Symbol | Description | | :--- | :--- | :--- | | 1 | **S#** | Chip Select (Active Low) - Activates the device. | | 2 | **Q** | Serial Data Output - Sends data to the Master. | | 3 | **W#** | Write Protect - Prevents hardware writes to the status register. | | 4 | **VSS** | Ground. | | 5 | **D** | Serial Data Input - Receives instructions/data from the Master. | | 6 | **C** | Serial Clock - Synchronizes data movement. | | 7 | **HOLD#** | Hold - Pauses communication without resetting the chip. | | 8 | **VCC** | Supply Voltage. | --- ### 3. Core Operational Features * **Instruction Set:** The device supports standard SPI opcodes, including `WREN` (Write Enable), `WRITE`, `READ`, and `RDSR` (Read Status Register). * **Block Protection:** Users can software-protect portions of the memory (Quarter, Half, or Whole) via the Status Register bits. * **Page Write Mode:** It supports writing up to 16 bytes in a single cycle, which significantly improves write throughput compared to byte-by-byte writing. * **Self-Timed Write Cycle:** The internal write cycle is self-timed, meaning the system can perform other tasks while the memory finishes storing the data (typically takes 5ms). --- ### 4. Part Number Breakdown: M95010-RBN6 * **M95:** SPI family of EEPROMs. * **010:** Density (1 Kbit). * **-R:** Operating voltage range (1.8V to 5.5V). * **BN:** Package code (e.g., Plastic Dual-in-line Package). * **6:** Industrial temperature range (-40°C to 85°C). ---
