MISSION VIEJO, Calif., 10 Dec. 2009. Holt Integrated Circuits Inc. in Mission Viejo, Calif., is introducing development kits for the company's HI-6120 and HI-6121 MIL-STD-1553remote terminal technology, which are single-chip, 3.3-volt devices with dual transceivers and 64 kilobytes of RAM, in surface-mount plastic packages.
Each MIL-STD-1553 data bus device has its own kit and provides the user with a reference design board, power supply, USB cable, and CD containing software and user's guide. The devices interface to an on-board Zilog ZNEOTM microprocessor which can be programmed over a USB using the supplied cable. The board also includes two external flash EEPROM devices for optional automatic initialization and bus interface transformers for connection to a MIL-STD-1553 bus.
The HI-6120 uses a 16-bit parallel host bus interface in a 100-pin PQFP package, while the HI-6121 uses a 4-wire serial peripheral host interface (SPI) and comes in a 52-pin PQFP or 64-pin QFN.
Included software demonstrates features of the devices, including auto-initialization, descriptor table setup, message illegalization, mode code handling, data buffering, and interrupt management.
