Astronics / EADS / Racal 7064 Single Slot Prototyping Module - Message-Based

The Astronics / EADS / Racal 7064 Single Slot Prototyping Module is a message-based VXIbus development platform designed for rapid prototyping and testing of custom hardware within VXI systems. This C-sized module delivers a complete prototyping environment with 82 square inches of development space, a 68000-based daughterboard CPU, and 96 buffered TTL control lines for direct circuit implementation. Engineers and system integrators use the 7064 across aerospace, defense, and industrial applications to validate new designs before production integration. ## Technical Specifications Interface & Architecture • Message-based interface, IEEE-488.2 compliant • C-sized VXIbus form factor with full VXIbus access • 68000-based daughterboard with CPU bus directly accessible to user • Upper half of 68000 address space available for user memory-mapped devices • Lower half reserved for I/O ports, on-board memory, and VXIbus registers Prototyping Resources • 82 square inches of development space; variants offer over 100 square inches • Twelve 8-bit individually configurable ports • 96 buffered TTL control lines, programmable in binary, octal, decimal, or hexadecimal • Digital I/O accessible in bit, byte, or word format • 0.1" × 0.1" (2.54 mm × 2.54 mm) grid for user I/O connectors • Support for DIP, PGA, PLCC, and Small Outline surface mount packages • 77 pairs of +5V/Gnd pads in development area (7064R variant) Power & Expansion • All seven VXIbus supply lines available to user, fused and EMI-filtered per VXIbus spec • Supports master/slave expansion with up to eleven slave 7064M modules controllable via VXI local bus • Local bus access for proprietary signals or expansion Memory & Firmware • Shared memory capability • On-board RAM and ROM for user-definable firmware ## Key Features • Message-based architecture simplifies software integration with VXI test systems • Direct VXIbus CPU access eliminates interface bottlenecks • Modular expansion supports scaled system architectures • All power rails fused and filtered to meet VXIbus specifications • User-definable VXIbus registers for custom control logic ## Typical Applications Aerospace and defense instrumentation, industrial measurement systems, custom sensor interfaces, embedded control prototyping, and VXI system expansion. ## Compatibility & Integration VXIplug&play drivers and installation disk included for Windows, Windows 95, and Windows NT environments. Full VXIbus register compliance ensures interoperability with standard VXI chassis and controllers.
