HI-3585, HI-3586
ARINC 429 Terminal IC with SPI Interface
GENERAL DESCRIPTION
The HI-3585 from Holt Integrated Circuits is a silicon gate CMOS device for interfacing a Serial Peripheral Interface (SPI) enabled microcontroller to the ARINC 429 serial bus. The device provides one receiver with user-programmable label recognition for any combination of 256 possible labels, 32 x 32 Receive FIFO and analog line receiver. The independent transmitter has a 32 x 32 Transmit FIFO and built-in line driver. The status of the transmit and receive FIFOs can be monitored using the programmable external interrupt pin, or by polling the HI-3585 Status Register.
