24-Channel ARINC 429 Development Kit
Holt Integrated Circuits today announced the release of a new ARINC 429 application development kit, featuring 16 ARINC 429 receive channels and 8 ARINC 429 transmit channels. The data management engine is comprised of Holt’s recently announced HI-3220 IC, which integrates all 24 channels in a tiny 10mm x 10mm footprint. The kit hardware includes a CPU control board with ARM Cortex M3 16/32-bit microprocessor, debug interface and regulated 3.3VDC power supply, and a HI-3220 daughter card, configurable with various DIP switches.   Read more
24-Channel ARINC 429 Data Management IC with Integrated Line Receivers
Holt Integrated Circuits today expanded its ARINC 429 data management capability with the announcement of five new devices. The HI-3220 family is capable of managing, storing and forwarding avionics data between 16 ARINC 429 receive channels and 8 ARINC 429 transmit channels in a tiny 10x10mm2 footprint. Integrated line receivers and a compact serial peripheral host interface (SPI) save significant amounts of space at such high channel densities, making these devices ideal for multi-channel applications such as data concentrators. An option for 8 receive and 4 transmit channels is also available in an even smaller, cost effective 7x7mm2 QFN package footprint.   Read more
