Performance Technologies PT-VME141 VME64 Single Board Controller 32-Bit RS-232

Performance Technologies PT-VME141 VME64 Single Board Controller 32-Bit RS-232

The Performance Technologies PT-VME141 is an extensible single board controller designed for the VME64 bus standard. It is built around a 32-bit microprocessor with internal cache and parity checking, and features the EPAK interface extension capability that allows the board's functionality to be expanded through Performance Technologies' modular EPAK hardware. A front-panel RS-232 connector provides serial communication access directly from the panel.

Applications

VME64 single board controllers like the PT-VME141 are used in embedded computing, industrial automation, military, aerospace, and telecommunications applications where a rugged, modular, and real-time-capable processor board is required. The VMEbus standard — developed in the early 1980s and formalized as IEEE 1014 — became a dominant architecture for mission-critical embedded systems through the 1990s and 2000s, and continues to see active use in long-lifecycle industrial and defense platforms where legacy VME infrastructure is maintained. Performance Technologies specialized in VMEbus and CompactPCI products for telecom and networking equipment; the EPAK extension system was a key part of their platform, allowing different I/O and protocol mezzanines to be fitted to a common SBC carrier. This board dates from the mid-to-late 1990s era of VMEbus computing, identifiable by its chip population and the VME64 standard designation, which extended the original VMEbus to 64-bit data transfers and improved addressing. It is suited for system maintainers keeping VME-based platforms operational, system integrators, or researchers working with VMEbus backplane hardware.
