Low Power Monolithic CMOS 3.3V MIL-STD-1553 BC/RT/MT Message Processor

Thursday, June 02, 2005

The introduction of Holt's HI-6110 COTS MIL-STD-1553 Message Processor is a true single-chip 3.3V CMOS device designed to implement the 1553 data communications protocol between a host processor and a dual redundant 1553 data bus. The HI-6110 is configurable in BC / RT / MT operating modes and is designed to take full advantage of the existing host processor/memory.

Mission Viejo, CA (June 2, 2005) – Holt Integrated Circuits today announced the availability of the HI-6110, single-chip CMOS 3.3 volt MIL-STD-1553 Message Processor. The HI-6110 is a CMOS integrated circuit designed to implement the MIL-STD-1553 data communications protocol between a host processor and a dual redundant 1553 data bus, and supports MIL-STD-1553B Notice 2 and MIL-STD-1760 Stores Management.

Designers employing the new HI-6110 will be able to implement BC/RT/MT operating modes with all of the advantages of a single-chip CMOS device, including;

  • On-chip bus transceivers
  • Exceptionally low power consumption (less than 500mW)
  • World's smallest footprint for a MIL-STD-1553 terminal device
  • Easy to understand operation with no legacy architecture to understand and support
  • Off-chip memory to reduce cost and pin-count
  • Significant cost savings over hybrid terminal products currently on the market

The HI-6110 is a single-chip protocol device and includes on-board dual redundant transceivers as well as Manchester Encoder /Decoders, MIL-STD-1553 message-level protocol engine, and sufficient on-chip data storage for single message buffering. With exceptionally low power the device dissipates less than 500 mW on-chip power at 100% duty cycle. The HI-6110 may be configured as a Bus Controller (BC), a Remote Terminal (RT), an addressed Monitor Terminal (MT), or as a non-addressed MT. All that is needed to interface to the MIL-STD-1553 bus is an isolation transformer for each channel (also available from Holt). The host CPU communicates with the HI-6110 over a 16-bit parallel Input/Output bus. The status of message sequencing and the data transfers are flagged by pins and register bits. Registers are provided for configuration, status information, error information, and the type of the currently executing command.

The HI-6110 Message Processor introduced by Holt is the first new bottoms up design provided to the market in years. Care has been taken to provide customers only what they need, and eliminate unnecessary legacy operating modes. The HI-6110 uses system memory for 1553 message data which is configured by the user to specifically meet the needs of the application. As a result, the device can be offered in a small package that takes full advantage of the host processor / memory at a price offering significant cost savings to the system designer. The HI-6110 is offered in either a 52-pin plastic quad flat pack (PQFP) or a 60-pin plastic chip-scale package.

“Designers of military avionics data bus systems have waited a long time for a simple, fully integrated MIL-STD-1553 terminal IC that acts as a peripheral device to the system’s host processor,” says David Mead, Executive Vice President and COO of Holt Integrated Circuits. “The 3.3 volt HI-6110, with its exceptionally low power consumption, allows the designer to focus on their system application, and hand off the detail protocol management to the message processor.”

Holt Integrated Circuits has the largest selection of MIL-STD-1553 and ARINC 429 ICs available from any supplier. Products range from 3.3V and 5V transceivers and Manchester Encoder/Decoders to more highly integrated products, including the new 3.3V single-chip MIL-STD-1553 terminal and the soon to be released HI-1575 “smart transceiver”. Screening options include Industrial and full Mil-Temp ranges.

Engineering samples of the HI-6110PQI in the 52-pin PQFP package are now available from Holt, along with an accompanying Remote Terminal evaluation / demonstration board to customers wishing to evaluate the device for new production designs.
