HI-3593
3.3V ARINC 429 Dual Receiver,
Single Transmitter with SPI Interface
GENERAL DESCRIPTION
PIN CONFIGURATIONS (Top View)
The HI-3593 from Holt Integrated Circuits is a CMOS
integrated circuit for interfacing a Serial Peripheral
Interface (SPI) enabled microcontroller to the ARINC 429
serial bus. The device provides two receivers, each with
user-programmable label recognition for any combination
of 256 possible labels, 32 x 32 Receive FIFO, 3 priority-
label quick-access double-buffered registers and analog
line receiver. The independent transmitter has a 32 x 32
Transmit FIFO and built-in line driver. The line driver
operates from a single 3.3V supply and includes on-chip
DC/DC converter to generate the bipolar ARINC 429
differential voltage levels needed to directly drive the
ARINC 429 bus. The status of the transmit and receive
FIFOs and priority-label buffers can be monitored using
the programmable external interrupt pins, or by polling the
HI-3593 Status Registers. Other features include a
programmable option of data or parity in the 32nd bit, and
the ability to switch the bit-signifiance of ARINC 429 labels.
Pins are available with different input resistance and
output resistance values which provides flexibility when
using external lightning protection circuitry.
The Serial Peripheral Interface minimizes the number of
host interface signals resulting in a small footprint device
that can be interfaced to a wide range of industry-standard
microcontrollers supporting SPI. Alternatively, the SPI
signals may be controlled using just four general purpose
I/O port pins from a microcontroller or custom FPGA. The
SPI and all control signals are CMOS and TTL compatible
and support 3.3V operation.
The HI-3593 applies the ARINC 429 protocol to the
receivers and transmitter. ARINC 429 databus timing
comes from a 1 MHz clock input, or an internal counter can
derive it from higher clock frequencies having certain fixed
values, possibly the external host processor clock.
