Smallest MIL-STD-1553 remote terminal solution from Holt Integrated Circuits

Holt Integrated Circuits has expanded its portfolio of MIL-STD-1553 products with the release of HI-6120 and HI-6121 devices that offer a single-chip, 3.3V MIL-STD-1553 remote terminal solution including dual transceivers.

Both devices handle all aspects of the MIL-STD-1553 protocol such as 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.

The HI-6120 and HI-6121 devices features include programmable memory management with up to four data buffering modes, internal illegalization capability for subaddress, command T/R bit, broadcast vs non-broadcast and word count or mode code (4096 combinations), simplified mode command handling, programmable interrupts with 16-interrupt log buffer, optional illegal command detection and optional broadcast command recognition.

The HI-6120 and HI-6121 can also be configured for automatic self-initialization, further minimizing external host interaction. An SPI port reads data from an external serial EEPROM memory to configure the internal RAM, illegalization table and host interrupts.

"Holts unique single-chip approach offers customers a less expensive, more reliable and compact solution with faster lead-times than existing multi-chip module solutions on the market today," said Anthony Murray, Director of Business Development at Holt. "The devices can operate with minimum host intervention, offering the user maximum flexibility with a multitude of programmable features".

Industrial temperature range: -40°C to + 85°C
Extended temperature range: -55°C to + 125°C

Package:
HI-6120 with 16-bit parallel host bus interface: 100-pin PQFP package
HI-6121 with 4-wire SPI: 52-pin PQFP or 64-pin QFN package. The 64-pin QFN is the small remote terminal solution at 9mm x 9mm x 1mm
