Holt Integrated Circuits, a world leader in communications bus IC's for the avionics and military industries, today announced the introduction of HI-6140, a 3.3V, 10Mbit/sec EBR-1553 BC/MT/RT solution. The device is designed for Enhanced Bit Rate 10Mbps MIL-STD-1553 or MIL-STD-1760 applications, such as Miniature Munitions Stores Interface (MMSI) or EBR-1553.

The HI-6140 uses Holt's 20Mbit/sec RS-485 transceivers to connect directly to the EBR-1553 bus. The device produces Manchester II bi-phase encoded data for transmission on the RS-485 busses and automatically accounts for all response times necessary to comply with 10Mbps EBR-1553. The HI-6140 may be used in a multi-drop EBR-1553 bus or can function as an RT in an SAE AS5652 compliant star connection architecture.

"Holt is very pleased to further expand its 1553 range of products. The new HI-6140, modeled on Holt's proven HI-6130 BC/MT/RT device, provides customers with a compact, reliable, low cost EBR-1553 solution," said Anthony Murray, Director of Business Development at Holt.

In addition to the EBR-1553 features, the HI-6140 includes many features of Holt's flagship BC/MT/RT 1Mbps MIL-STD-1553 terminal, HI-6130, including BC, MT or RT operation, 64k bytes on-chip RAM with optional error detection/correction, MT mode supporting IRIG-106 Chapter 10 packet format and 64-word interrupt log buffer.

The device is available in Industrial -40oC to +85oC, or Extended -55oC to +125oC temperature ranges in a 100-pin PQFP package. Optional burn-in is available on the extended temperature range. Samples are available immediately.
