HI-3210

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 automatically re-format, re-label, re-packetize and retransmit data from ARINC 429 receive buses to ARINC 429 transmit buses.

A 32K x 8 on-board memory allows received data to be logically organized and automatically updated as new ARINC 429 labels.

An auto-initialization feature allows configuration information to be up-loaded from an external EEPROM on reset to facilitate rapid start-up or operation without a host CPU.

The HI-3210 interfaces directly with Holt’s HI-8448 octal ARINC 429 receiver IC and HI-8596 or HI-8592 ARINC 429 line drivers.
