GENERAL DESCRIPTION

The HI-3210 from Holt Integrated Circuits is a single chip CMOS data management IC capable of managing, storing and forwarding avionics data messages between eight ARINC 429 receive channels and four ARINC 429 transmit channels.

The ARINC 429 buses may be operated independently, allowing a host CPU to send and receive data on multiple buses, or the HI-3210 can be programmed to automati cally re-format, re-label, re-packetize and re-transmit data from ARINC 429 receive buses to ARINC 429 transmit buses.
