ELECTRONICS: API Technologies Corp. announced the release of Terminal+ (pronounced Terminal Plus), the newest National Hybrid 1553 data bus product. The compact National Hybrid Terminal+ offers a multi-protocol data bus interface with integrated transformers and can function as a simultaneous monitor/remote terminal, a programmable bus controller, a remote terminal or a bus monitor.
Designed for both reliability and durability, the Terminal+ ensures the integrity of all data and control structures. The Terminal+ with integrated transformers occupies minimal board space and simplifies PCB layout as well as electrical design.
The cost-effective component, which serves as an interface between a dual redundant bus and a host processor, supports both MIL-STD-1553 and MIL-STD-1760 functionality in a single, low-power component. This makes the Terminal+ ideal for space-constrained, high-reliability rugged applications that require demanding processing power as found in military and commercial avionics.
The subsystem interface can be a local bus or a PCI bus. The local bus interface appears to the host processor as 64K words of 16-bit wide, dual port memory controlled by standard RAM signals. The PCI interface is a 32-bit 33 MHz target. The Terminal+ easily interfaces with all popular processors and buses, since no external logic is required.
The Terminal+ features a protocol ASIC, which controls the multi-protocol functions, two +5 or +3.3V monolithic transceivers and a 64k x 16 shared RAM. All logic I/O is 3.3V that is 5V tolerant. The only external component required is a 20 MHz clock. The open memory architecture increases design flexibility and reduces software development time and effort.
The built-in interrupt controller uses an internal FIFO that stores message header information. Six pending interrupts and an overflow interrupt can be pushed on to the FIFO, which can be configured to revolve or stop when full.
The Terminal+ implements complete error checking in all operational modes: bus controller, remote terminal, bus monitor and bus monitor/remote terminal. Multiple autonomous data tables ensure data integrity.
The Terminal+ measures 1.05 x 0.75 x 0.185 inch and is available in a ball grid array with 117 large pitch, oversized balls to eliminate solder shorting risks. Operating temperature is the full military range of -55 to 125C (-67 to 257F) and storage temperature is -65 to 150C (-85 to 302F).
