ARINC 429 System on a Chip
GENERAL DESCRIPTION
The HI-8582 from Holt Integrated Circuits is a silicon gate
CMOS device for interfacing a 16-bit parallel data bus
directly to the ARINC 429 serial bus. The HI-8582 design
offers many enhancements to the industry standard HI-
8282 architecture. The device provides two receivers each
with label recognition, 32 by 32 FIFO, and analog line
receiver. Up to 16 labels may be programmed for each
receiver. The independent transmitter has a 32 by 32 FIFO
and a built-in line driver. The status of all three FIFOs can
be monitored using the external status pins, or by polling
the HI-8582’s status register. Other new features include a
programmable option of data or parity in the 32nd bit, and
the ability to unscramble the 32 bit word. Also, versions
are available with different values of input resistance and
output resistance to allow users to more easily add external
lightning protection circuitry. The device can be used at
nonstandard data rates when an option pin, NFD, is
invoked.
The 16-bit parallel data bus exchanges the 32-bit ARINC
data word in two steps when either loading the transmitter
or interrogating the receivers. The databus, and all control
signals are CMOS and TTL compatible.
The HI-8582 applies the ARINC protocol to the receivers
and transmitter. Timing is based on a 1 Megahertz clock.
Although the line driver shares a common substrate with
the receivers, the design of the physical isolation does not
allow parasitic crosstalk, and thereby achieves the same
isolation as common hybrid layouts.

FUNCTIONAL DESCRIPTION
CONTROL WORD REGISTER
The HI-8582 contains a 16-bit control register which is used to
configure the device. The control register bits CR0 - CR15 are
loaded from BD00 - BD15 when CWSTR is pulsed low. The control
register contents are output on the databus when SEL=1 and RSR
is pulsed low. Each bit of the control register has the following
function:

STATUS REGISTER
The HI-8582 contains a 9-bit status register which can be
interrogated to determine the status of the ARINC receivers, data
FIFOs and transmitter. The contents of the status register are output
on BD00 - BD08 when the RSR pin is taken low and SEL = 0. Unused
bits are output as zeros. The following table defines the status
register bits.

Once a valid ARINC word is loaded into the FIFO, then EOS
clocks the data ready flag flip flop to a "1", D/R1 or D/R2 (or both)
will go low. The data flag for a receiver will remain low until both
ARINC bytes from that receiver are retrieved and the FIFO is
empty. This is accomplished by first activating EN with SEL, the
byte selector, low to retrieve the first byte and then activating EN
with SEL high to retrieve the second byte. EN1 retrieves data
from receiver 1 and EN2 retrieves data from receiver 2.
Up to 32 ARINC words may be loaded into each receiver’s FIFO.
The FF1 (FF2) pin will go low when the receiver 1 (2) FIFO is full.
Failure to retrieve data from a full FIFO will cause the next valid
ARINC word received to overwrite the existing data in FIFO
location 32. A FIFO half full flag HF1 (HF2) goes low if the FIFO
contains 16 or more received ARINC words. The HF1 (HF2) pin is
intended to act as an interrupt flag to the system’s external
microprocessor, allowing a 16 word data retrieval routine to be
performed, without the user needing to continually poll the HI-
8582’s status register bits.
LABEL RECOGNITION
The chip compares the incoming label to the stored labels if label
recognition is enabled. If a match is found, the data is processed.
If a match is not found, no indicators of receiving ARINC data are
presented. Note that 00(Hex) is treated in the same way as any
other label value. Label bit significance is not changed by the
status of control register bit CR15. Label bits BD00-BD07 are
always compared to received ARINC bits 1-8 respectively.
LOADING LABELS
After a write that takes CR1 from 0 to 1, the next 16 writes of data
(PL pulsed low) load label data into each location of the label
memory from the BD0-7 pins. The PL1 pin is used to write label
data for receiver 1 and PL2 for receiver 2. Note that ARINC word
reception is suspended during the label memory write sequence.
READING LABELS
After the write that changes CR1 from 0 to 1, the next 16 data
reads of the selected receiver (EN taken low) are labels. EN1 is
used to read labels for receiver 1, and EN2 to read labels for
receiver 2. Label data is presented on DB0-DB7.
When writing to, or reading from the label memory, SEL must be a
one, all 16 locations should be accessed, and CR1 must be
written to zero before returning to normal operation. Label
recognition must be disabled (CR2/3=0) during the label read
sequence.
TRANSMITTER
FIFO OPERATION
The FIFO is loaded sequentially by first pulsing PL1 to load byte 1
and then PL2 to load byte 2. The control logic automatically loads
the 31 bit word (or 32 bit word if CR4=0) in the next available
position of the FIFO. If TX/R, the transmitter ready flag is high
(FIFO empty), then up to 32 words, each 31 or 32 bits long, may
be loaded. If TX/R is low, then only the available positions may be
loaded. If all 32 positions are full, the FFT flag is asserted and the
FIFO ignores further attempts to load data.
A transmitter FIFO half-full flag HFT is provided. When the
transmit FIFO contains less than 16 words, HFT is high,
indicating to the system microprocessor that a 16 ARINC word
block write sequence can be initiated.
In normal operation (CR4=1), the 32nd bit transmitted is a parity
bit. Odd or even parity is selected by programming control
register bit CR12 to a zero or one. If CR4 is programmed to a 0,
then all 32-bits of data loaded into the transmitter FIFO are
treated as data and are transmitted.
