The XVME-172 provide OEMs and solutions developers with an ideal platform for embedded monitoring and control applications. They allow an OEM to minimize engineering expenses while integrating value-added hardware and software applications onto an off-the-shelf product.

In order to provide this wide range of solutions, these processor modules include a variety of CPU, memory, and interface features such as floating point support, Ethernet, SCSI, and VME.

The inclusion of the new Petra II application-specific integrated circuit (ASIC), which replaces functions formerly implemented in the IP2 chip, MC2 chip, and MCECC chip, improves the performance of the memory subsystem.

VMEbus Interface
The VMEbus interface ASIC includes a local bus to and from the VMEbus DMA controller, VME board support features, and a global control and status register (GCSR) for CPU communications. The ASIC also supports the VME D64 specification, further enhancing system performance.

Processor
The XVME-172 is powered by a Motorola 25 MHz MC68LC040 32-bit CPU with 8 KB of cache and MMU.

Below is a summary of the XVME-172 features:

• Motorola 25 MHz MC68LC040 enhanced 32-bit CPU with 8 KB cache and MMU
• A32/D64 VMEbus master/slave interface with system controller function
• High-performance DMA support for VMEbus D64 and local bus memory burst cycles
• 16 MB of configurable SDRAM
• 512 KB SRAM with battery backup
• 1 MB Flash memory for onboard monitor/debugging or user-installer firmware
• 8 K x 8NVRAM and time-of-day clock with battery backup
• Two serial DB-25 communication ports: console port configurable as EIA-232-D DCE, second port also configurable to EIA-422 (v36) DTE/DCE
• Four 16-bit Industry Pack (IP) ports with one DMA channel per port
• SCSI and Ethernet interfaces
• Six 32-bit timers, one watchdog timer
