HI-3200, HI-3201
AVIONICS DATA MANAGEMENT ENGINE /
ARINC 429 - CAN BUS BRIDGE
GENERAL DESCRIPTION
The HI-3200 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 CAN buses may be operated inde-
pendently, 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 re-
transmit data from ARINC 429 receive buses to ARINC
429 transmit buses, as well as from ARINC 429 to CAN or
CAN to ARINC 429.
A 32K x 8 on-board memory allows received data to be
logically organized and automatically updated as new
ARINC 429 labels or CAN frames are received.
An auto-initialization feature allows configuration informa-
tion 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 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.
