Holt's ARINC 429 Protocol IC HI-35930
HI-35930/31/32/33 is a CMOS device for directly connecting SPI-compatible microcontrollers to the ARINC 429 bus.
The HI-35930 from Holt is a CMOS integrated circuit designed to connect SPI-compatible microcontrollers to the ARINC 429 serial bus. This device features two receivers, each with user-programmable label recognition for any combination of 256 possible labels, a 32×32 receive FIFO, three priority label quick access double buffer registers, and an analog line receiver. Both line receivers meet the lightning protection requirements of RTCA/DO-160G, Section 22, Level 3. The independent transmitter includes a 32×32 transmit FIFO and an integrated line driver. The line driver operates on a single 3.3V power supply and includes an on-chip DC/DC converter that generates the bipolar ARINC 429 differential voltage levels necessary to directly drive the ARINC 429 bus. The status of the transmit and receive FIFOs and the priority label buffer can be monitored using a programmable external interrupt pin or by polling the status register.
