Small MIL-STD-1553 databus interface from Holt receives formal validation for a wide variety of avionics applications

MISSION VIEJO, Calif., 19 March 2013. Holt Integrated Circuits Inc. in Mission, Viejo, Calif., is announcing formal MIL-STD-1553 RT validation of the HI-6130/31 BC/MT/ RT multi-terminal 1553 databus interface.

Validation was at Test Systems Inc. in Phoenix, an independent Air Force-approved testing service for MIL-STD-1553 remote terminals.

The HI-6130/31 devices provide a single-chip, 3.3-volt MIL-STD-1553 BC/MT/RT terminal, including dual transceivers, in compact surface-mount plastic packages.

The HI-6130 uses a 16-bit parallel host bus interface in a 100-pin PQFP package. The HI-6131 uses a 4-wire serial peripheral host Interface (SPI) and comes in a 64-pin PQFP or 64-pin QFN.

The 64-pin QFN is a tiny BC/MT/RT multi-terminal that measures 9 by 9 by 1 millimeter. Both devices handle the MIL-STD-1553 protocol, including message encoding, decoding, error detection, illegal command detection, and data buffering.

Host data management is simplified by storing message information and data within the on-chip 32K x 16-bit static RAM, which has an error detection and correction option.

The devices come in versions that operate in temperatures from -40 to 85 degrees Celsius, or from -55 to 125 C, with optional burn-in available on the extended temperature range.

Each device has a dedicated developer's kit which includes a demonstration board with on-board ARM Cortex M3 microprocessor, a 32-kilobyte KickStart edition of IAR Systems Embedded Workbench IDE, cables, and power supply.
