The **M93C76-RMB6TP** is a specific variant of the 8-Kbit serial MICROWIRE EEPROM manufactured by STMicroelectronics. It is commonly used in automotive and industrial applications for non-volatile data storage. --- ## 1. Technical Specifications Below are the primary electronic characteristics of the M93C76-RMB6TP: | Parameter | Specification | | :--- | :--- | | **Memory Size** | 8 Kbit (8192 bits) | | **Memory Organization** | User-selectable: 1024 x 8 bits OR 512 x 16 bits | | **Interface** | MICROWIRE (3-wire serial) | | **Operating Voltage** | 1.8V to 5.5V | | **Clock Frequency** | 2 MHz (at 4.5V - 5.5V) | | **Write Cycle Time** | 5 ms (Maximum) | | **Package** | SO8N (narrow body) | | **Temperature Range** | -40°C to +85°C (Industrial Grade) | --- ## 2. Key Electronic Features * **Organization Select (ORG):** A dedicated pin allows the user to choose between 8-bit or 16-bit data architecture. * **Sequential Read:** It supports reading the entire memory array sequentially without re-sending addresses. * **Ready/Busy Status:** During a write cycle, the data output (DO) pin can be polled to signal when the internal programming is complete. * **High Endurance:** It is rated for **4 million write cycles** and **200 years of data retention**, making it highly reliable for long-term storage. * **Write Protection:** Includes software-executable instructions (`WEN` and `WDS`) to prevent accidental data erasure. --- ## 3. Pinout Configuration (SO8) The device typically follows the standard MICROWIRE 8-pin layout: | Pin Number | Symbol | Description | | :--- | :--- | :--- | | 1 | S (CS) | Chip Select | | 2 | C (SK) | Serial Clock | | 3 | D (DI) | Serial Data Input | | 4 | Q (DO) | Serial Data Output | | 5 | Vss | Ground | | 6 | ORG | Organization Select (High = x16, Low/NC = x8) | | 7 | DU/NC | Don't Use / No Connect | | 8 | Vcc | Supply Voltage | --- ## 4.
