MOTOROLA MVME162-220 Embedded controller

The MOTOROLA MVME162-220 embedded controller is a powerful embedded system solution. The following is a detailed overview of its features:

Microprocessor options:
The MVME162-220 offers a variety of microprocessor options, including the 32 MHz MC68040 enhanced 32-bit microprocessor with 8KB cache, MMU (Memory Management Unit), and FPU (Floating-point Unit).
Meanwhile, this controller also supports the optional 25 MHz MC68040 32-bit microprocessor or the 25 MHz MC68LC040 enhanced 32-bit microprocessor, both with corresponding cache and memory management functions.
Memory and Storage
The MVME162-220 offers 4, 8 or 16MB of shared DRAM (Dynamic Random Access Memory) to meet the data processing requirements of various applications.
The controller is also equipped with 512KB of SRAM (Static Random Access Memory) and a spare battery to ensure the persistence of data.
In addition, it also includes 1MB of flash memory, which can be used for on-board monitors/debuggers or user-installed firmware.

Interface and Communication
The MVME162-220 is equipped with A32/D64 VME bus master/slave interfaces, supporting high-performance system connection and communication.
Two serial communication ports are provided. Among them, the console port is used as EIA-232-D DTE, and the second port can be configured by the user for EIA-232-D/EIA-422 (V.36) DTE/DCE to meet the requirements of various communication protocols.
The controller also includes four 16 or 32-bit IndustryPack® ports, each with a DMA (Direct Memory Access) channel for efficient data transfer.
Timer and Monitoring
The MVME162-220 is equipped with six 32-bit timers (four of which do not come with VMEbus) and one watchdog timer for precise system control and fault monitoring.
Extended options:
It provides an optional SCSI bus interface and supports 32-bit local bus burst DMA to meet the requirements of large-scale data storage and transmission.
Optional Ethernet transceiver interface with 32-bit local bus DMA, facilitating the controller’s connection to Ethernet for network communication.
Other features:
The MVME162-220 also includes a 32-pin PLCC EPROM socket for storing and loading firmware.
The four-level requester, seven-level interrupter and seven-level interrupt handler that support VMEbus ensure the efficient operation and fault handling of the system.
The remote RESET/ABORT/STATUS control function facilitates users to manage the system status remotely.
On-board debuggers and diagnostic firmware facilitate system development and troubleshooting.
IndustriPack interface:
One key feature of the MVME162-220 is the IndustriPack logic interface, which provides a 32-bit data path for the IndustriPack module and can be connected to the local MC68040 bus.
The IndustriPack module offers a variety of connections to “real-world” applications, such as I/O, control, interfaces, analog and digital functions.
Up to four single-width or two double-width IndustriPack modules can be installed on the MVME162, but it can still only occupy one VME slot.
Summary: The MOTOROLA MVME162-220 embedded controller is a feature-rich and flexibly configured embedded system solution, suitable for various industrial automation, control systems and network communication applications.
