GENERAL DESCRIPTION

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.
