ARINC 429
Terminal IC with SPI Interface
GENERAL DESCRIPTION
The HI-3585 from Holt Integrated Circuits is a silicon gate
CMOS device for interfacing a Serial Peripheral Interface
(SPI) enabled microcontroller to the ARINC 429 serial bus.
The device provides one receiver with user-programmable
label recognition for any combination of 256 possible
labels, 32 x 32 Receive FIFO and analog line receiver.
The independent transmitter has a 32 x 32 Transmit FIFO
and built-in line driver. The status of the transmit and
receive FIFOs can be monitored using the programmable
external interrupt pin, or by polling the HI-3585 Status
Register. 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 or 5V operation.
The HI-3585 applies the ARINC 429 protocol to the
receiver 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.
The HI-3586 is functionally identical to the HI-3585 except
it includes digital transmitter output pins 429D1 and 429D0
instead of a built-in line driver. This allows the designer to
take advantage of Holt’s single supply rail line drivers,
such as the 5V HI-8592 or 3.3V HI-8596.
FEATURES
· ARINC specification 429 compliant

· Independent data rates for Transmit and Receive
· High-speed, four-wire Serial Peripheral Interface
· Label bit-order control
· 32nd transmit bit can be data or parity
· Self test mode
· Low power
· Industrial & extended temperature ranges

FUNCTIONAL DESCRIPTION (cont.)
TRANSMITTER
FIFO OPERATION
The Transmit FIFO is loaded with ARINC 429 words awaiting
transmission. SPI op code 0E hex writes up to 32 ARINC words
into the FIFO, starting at the next available FIFO location. If Status
Register bit SR3 equals “1” (FIFO empty), then up to 32 words (32
bits each) may be loaded. If Status Register bit SR3 equals “0”
then only the available positions may be loaded. If all 32 positions
are full, Status Register bit SR5 is asserted. Further attempts to
load the Transmit FIFO are ignored until at least one ARINC word is
transmitted.
In normal operation (Control Register bit CR3 = ”1”), the 32nd bit
transmitted is a word parity bit. Odd or even parity is selected by
programming Control Register bit CR9 to a “0” or “1” respectively. If
Control Register bit CR3 equals “0”, all 32 bits loaded into the
Transmit FIFO are treated as data and are transmitted.
SPI op code 11 hex asynchronously clears all data in the Transmit
FIFO. The Transmit FIFO should be cleared after a self-test before
starting normal operation to avoid inadvertent transmission of test
data.
The Transmit FIFO half-full flag (Status Register bit SR4) equals “0”
when the Transmit FIFO contains less than 16 words. When SR4
equals “0”, the system microprocessor can safely initiate a 16-word
ARINC block-write sequence.

HI-3586 OPTION
The HI-3586 is functionally identical to the HI-3585 except
it does not include an on-chip ARINC 429 Line Driver.
Instead, digital output pins 429D1 and 429D0 may be used
to drive an external ARINC 429 line driver. This
3.3V
configuration is useful if the desiger wishes to take
advantage of Holt’s single supply rail line drivers, such as
the 5V Hi-8592 or 3.3V HI-8596.
