HI-3588

July 2012 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. The Serial Peripheral Interface minimizes the number of host interface signals allowing for a small footprint device which can be interfaced to a wide variety of industrystandard microcontrollers supporting SPI. ...
