Dual IndustryPack logic interface for embedded monitoring and control applications

The MVME162P2 embedded controller provides a powerful and functional processor which can be customer-configured for specific applications.

The MVME162P2 extends its range of solutions by boosting the performance level and increasing the number of options. This flexibility allows a user to configure cost-ffective solutions ranging from embedded controllers to single-board computers. With the compute power of the MC68040 and the flexibility of the IndustryPack mezzanine interface, the MVME162P2 combines the mechanical ruggedness of VME with the cost effectiveness of PC-type products.

The inclusion of the new “Petra” application-specific integrated circuit (ASIC), which replaces functions formerly implemented in the IP2 chip and MC2 chip, improves the performance of the memory subsystem. Memory configuration switches enable the customer to tailor memory size for applications requiring smaller memory configurations.

IndustryPack Interface

A key feature of the MVME162P2 is the IndustryPack interface. IndustryPack modules provide a wide variety of connectivity to “real-world” I/O. Expansion is accomplished by

means of a mezzanine board mounted to the MVME162P2.

Up to two single-wide IndustryPack modules can be installed on the MVME162P2 and still occupy only one VME slot.

VMEbus Interface

VMEbus interface functionality is provided by the VMEchip2 ASIC designed by Motorola. In addition to controlling the system’s VMEbus functions, the VMEchip2 includes a local bus to/from VMEbus DMA controller, VME board support features, as well as global control and status register (GCSR) for interprocessor communications. The MVME162P2 also provides support for the VME D64 specification within the VMEbus interface, further enhancing system performance.

For deeply embedded applications, versions of the MVME162P2 are available without the VMEbus interface.

These versions have power and ground connections through the P1 VMEbus connector.

Peripheral Interface

Peripheral I/O connections for the MVME162P2 series are located on the front panel of the module. Serial port connection is via four RJ-45 connectors. SCSI devices are interfaced via an industry-standard 68-pin connector. A DB-15 connector is used for Ethernet. IndustryPack I/O signals are available via 50-pin connectors behind the front panel for connecting external I/O devices.

Memory Options

The MVME162P2 provides users with a variety of data storage options such as SDRAM with ECC option, EPROM/ROM, Flash, and battery-backed SRAM.

Software Support

The MVME162P2 is supported by a wide range of real-time kernels and embedded operating systems.
