HI-3588
ARINC 429 Receiver with SPI Interface
GENERAL DESCRIPTION
The HI-3588 from Holt Integrated Circuits is a silicon gate CMOS device for interfacing a Serial Peripheral Interface (SPI) enabled microcontroller to an ARINC 429 serial bus. The device provides one receiver with user-programmable label recognition for any combination of 256 possible labels, a 32 by 32 Receive FIFO and an analog line receiver. Receive FIFO status can be monitored using the programmable external interrupt pin, or by polling the HI-3588 Status Register. Other features include the ability to switch the bit-signifiance of ARINC 429 labels. The ARINC input pins are available with different input resistance values to provide flexibility when adding external lightning protection circuitry.
