The MVME162-213 is an **embedded controller** manufactured by Emerson (previously Motorola) designed for use in various industrial automation and control systems. Here's a breakdown of the product details and specifications based on information gathered from multiple sources:

**Function:**

* The MVME162-213 acts as a processing unit within a control system. It acquires data from sensors and I/O modules, processes it based on programmed logic, and sends control signals to actuators or other devices.

**Specifications:**

* **Processor:** Motorola MC68LC040 or MC68040 (MC68040 has a built-in math coprocessor for floating-point calculations)
* **Memory:**
    * 1MB, 4MB, or 8MB of DRAM (Dynamic Random-Access Memory)
    * 512KB of SRAM (Static Random-Access Memory) with battery backup for non-volatile data storage
* **Bus Interface:** VMEbus (Versa Module Eurocard bus) for communication with other modules in the system
* **I/O (Input/Output):**
    * Two serial ports (EIA-232) for communication with external devices
    * Optional SCSI (Small Computer System Interface) bus interface for connecting mass storage devices
* **Other Features:**
    * Six onboard timers for generating timing signals or pulse-width modulation (PWM) outputs
    * Watchdog timer for system monitoring and error handling
    * Real-time clock (RTC) for timekeeping

**Additional Notes:**

* The MVME162-213 is a discontinued product. Emerson no longer manufactures it, but replacement parts or used units might be available through third-party vendors.
* The specific functionalities and capabilities of the MVME162-213 within a control system depend on the application and the programmer's implementation.

**Finding More Information:**

While the official datasheet from Emerson might be difficult to locate, here are some resources that can provide further details:

* **Alternative Datasheets:** Search online for "MVME162-213 datasheet" on engineering resource websites or industrial parts distributors. You might find datasheets from distributors or third-party sources.
* **User Manuals:** Look for "MVME162 user manual" or "MVME162-213 user guide" online. These resources might offer more in-depth explanations of the module's features and programming instructions.
* **Online Forums:** Search for forums or communities focused on industrial automation systems or classic Motorola/Emerson controllers. You might find discussions or resources about the MVME162 series where users share experiences or troubleshooting tips.

I hope this information is helpful! Even though the MVME162-213 is an older product, understanding its core functionalities and specifications can provide valuable insight into its role within industrial control systems.
