HI-3593PQI Description

Short technical summary and product information.

The HI-3593PQI from Holt Integrated Circuits is a CMOS integrated circuit designed to interface a Serial Peripheral Interface (SPI) enabled microcontroller to the ARINC 429 serial bus. This device features two receivers with user-programmable label recognition for any combination of 256 possible labels, a 32x32 Receive FIFO, and priority-label buffers. The independent transmitter includes a 32x32 Transmit FIFO and a built-in line driver.

Operating from a single 3.3V supply, the HI-3593PQI includes an on-chip DC/DC converter to generate the necessary bipolar ARINC 429 differential voltage levels for direct bus driving. It supports industrial and extended temperature ranges (-40°C to +85°C) and utilizes a 10MHz, four-wire SPI for host communication. The package is a 44-Pin Plastic Quad Flat Pack (PQFP) or MQFP.

Key features include independent data rates for transmit and receive, programmable options for the 32nd bit (data or parity), and the ability to switch the bit-significance of ARINC 429 labels. The SPI interface minimizes host interface signals, making it suitable for a wide range of microcontrollers.
