The HI-3200 / HI-3201 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, four ARINC 429 transmit channels and a single CAN / ARINC 825 data bus.
The ARINC 429 and ARINC 825 (CAN) buses may be operated independently, allowing a host CPU to send and receive data on multiple buses, or the HI-3200 can be programmed to automatically re-format, re-label, re-packetize and retransmit data from ARINC 429 receive buses to ARINC 429 transmit buses, as well as from ARINC 429 to ARINC 825 (CAN) or the other way around.
A 32K x 8 on-board memory allows received data to be logically organized and automatically updated as new ARINC 429 labels or ARINC 825 (CAN) frames are received.
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-3200 interfaces directly with Holt’s HI-8448 octal ARINC 429 receiver IC, HI-8596 or HI-8592 ARINC 429 line drivers and HI-3110 integrated ARINC 425 (CAN) controller / transceiver.
The HI-3201 is identical to the HI-3200 except it comes in an 80-pin PQFP package with eight instead of two ARINC 429 bit monitor pins.
