The HI-8582/HI-8583 from Holt Integrated Circuits are a
silicon gate CMOS devices for interfacing a 16-bit parallel
data bus directly to the ARINC 429 serial bus. The
HI-8582/HI-8583 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 X 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/HI-8583 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 HI-8582/HI-8583 apply 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
STATUS REGISTER
The HI-8582/HI-8583 contain 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:
The HI-8582/HI-8583 contain 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.

FUNCTIONAL DESCRIPTION (cont.)
The HI-8582/HI-8583 guarantee recognition of these levels with a
common mode Voltage with respect to GND less than ±4V for the
worst case condition (4.75V supply and 13V signal level).
ARINC 429 DATA FORMAT
Control register bit CR15 is used to control how individual bits in the
received or transmitted ARINC word are mapped to the HI-8582/
HI-8583 data bus during data read or write operations. The
following table describes this mapping:
BYTE 1
The tolerances in the design guarantee detection of the above
levels, so the actual acceptance ranges are slightly larger. If the
ARINC signal is out of the actual acceptance ranges, including the
nulls, the chip rejects the data.

If the NFD pin is high, the HI-8582/HI-8583 accept signals that meet

way the logic operation achieves this is described below:

The ARINC 429 specification contains the following timing specification for the received data:
1. Key to the performance of the timing checking logic is an accurate 1MHz clock source. Less than 0.1% error is recommended.

3. Each data bit must follow its predecessor by not less than 8
samples and no more than 12 samples. In this manner the bit

acceptable data bit rates are as follows:

2. The sampling shift registers are 10 bits long and must show
three consecutive Ones, Zeros or Nulls to be considered valid
data. Additionally, for data bits, the One or Zero in the upper bits
of the sampling shift registers must be followed by a Null in the
lower bits within the data bit time. For a Null in the word gap,
three consecutive Nulls must be found in both the upper and
lower bits of the sampling shift register. In this manner the minimum pulse width is guaranteed.

4. The Word Gap timer samples the Null shift register every 10
input clocks (80 for low speed) after the last data bit of a valid
reception. If the Null is present, the Word Gap counter is
incremented. A count of 3 will enable the next reception.
If NFD is held low, frequency discrimination is disabled and any
data stream totaling 32 bits is accepted even with gaps between
bits. The protocol still requires a word gap as defined in 4. above.

FUNCTIONAL DESCRIPTION (cont.)
RECEIVER PARITY
The receiver parity circuit counts Ones received, including the
parity bit. If the result is odd, then a "0" will appear in the 32nd bit.
RETRIEVING DATA
Once 32 valid bits are recognized, the receiver logic generates an
End of Sequence (EOS). Depending upon the state of control
register bits CR2-CR11, the received ARINC 32-bit word is then
checked for correct decoding and label matching before being
loaded into the 32 x 32 receive FIFO. ARINC words which do not
meet the necessary 9th and 10th ARINC bit or label matching are
ignored and are not loaded into the receive FIFO. The following
table describes this operation.

FUNCTIONAL DESCRIPTION (cont.)
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.
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 BD0-BD7.
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.
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/HI-8583 status register bits.
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.
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.
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.
LOADING LABELS
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.
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 BD00 - BD07 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.

DATA TRANSMISSION
When ENTX goes high, enabling transmission, the FIFO
positions are incremented with the top register loading into the
data transmission shift register. Within 2.5 data clocks the first
data bit appears at TXAOUT and TXBOUT. The 31 or 32 bits in
the data transmission shift register are presented sequentially to
the outputs in the ARINC 429 format with the following timing:

The word counter detects when all loaded positions have been
transmitted and sets the transmitter ready flag, TX/R, high.
The HI-8582 has 37.5 ohms in series with each line driver output.
The HI-8583 has 10 ohms in series. The HI-8583 is for applications
where external series resistance is needed, typically for lightning
protection devices.
REPEATER OPERATION
Repeater mode of operation allows a data word that has been
received by the HI-8582/HI-8583 to be placed directly into the
transmitter FIFO. Repeater operation is similar to normal receiver
operation. In normal operation, either byte of a received data word
may be read from the receiver latches first by use of SEL input.
During repeater operation however, the lower byte of the data word
must be read first. This is necessary because, as the data is being
read, it is also being loaded into transmitter FIFO which is always
loaded with the lower byte of the data word first. Signal flow for
repeater operation is shown in the Timing Diagrams section.
TRANSMITTER PARITY
HI-8582-10 and HI-8583-10
The parity generator counts the Ones in the 31-bit word. If
control register bit CR12 is set low, the 32nd bit transmitted will
make parity odd. If the control bit is high, the parity is even.
Setting CR4 to a Zero bypasses the parity generator, and allows
32 bits of data to be transmitted.
The HI-8582-10/HI-8583-10 options are similar to the HI-8582/
HI-8583 with the exception that they allow an external 10 Kohm resistor to be added in series with each ARINC input without affecting the ARINC input thresholds. This option is especially useful in
applications where lightning protection circuitry is also required.
SELF TEST
If control register bit CR5 is set low, the transmitter serial output
data are internally connected to each of the two receivers,
bypassing the analog interface circuitry. Data is passed
unmodified to receiver 1 and inverted to receiver 2. Taking TEST
high forces TXAOUT and TXBOUT into the null state regardless
of the state of CR5.
SYSTEM OPERATION
The two receivers are independent of the transmitter.
Therefore, control of data exchanges is strictly at the option of
the user. The only restrictions are:
1. The received data will be overwritten if the receiver FIFO
is full and at least one location is not retrieved before the next
complete ARINC word is received.
2. The transmitter FIFO can store 32 words maximum and
ignores attempts to load additional data if full.
Each side of the ARINC bus must be connected through a
10 Kohm series resistor in order for the chip to detect the correct
ARINC levels. The typical 10 volt differential signal is translated
and input to a window comparator and latch. The comparator levels are set so that with the external 10 Kohm resistors, they are
just below the standard 6.5 volt minimum ARINC data threshold
and just above the standard 2.5 volt maximum ARINC null threshold.
Please refer to the Holt AN-300 Application Note for additional
information and recommendations on lightning protection of Holt
line drivers and line receivers.
HIGH SPEED OPERATION
The HI-8582 and HI-8583 may be operated at clock frequencies
beyond that required for ARINC compliant operation. For operation
at Master Clock (CLK) frequencies up to 5MHz, please contact
Holt applications engineering.
POWER SUPPLY SEQUENCING
LINE DRIVER OPERATION
The line driver in the HI-8582/HI-8583 are designed to directly
drive the ARINC 429 bus. The two ARINC outputs (TXAOUT
and TXBOUT) provide a differential voltage to produce a +10 volt
One, a -10 volt Zero, and a 0 volt Null. Control register bit CR13
controls both the transmitter data rate, and the slope of the
differential output signal. No additional hardware is required to
control the slope. Programming CR13 to Zero causes a
100 kbits/s data rate and a slope of 1.5 µs on the ARINC outputs;
a One on CR13 causes a 12.5 kbit/s data rate and a slope of
10 µs. Timing is set by on-chip resistor and capacitor and tested
to be within ARINC requirements.
The power supplies should be controlled to prevent large currents
during supply turn-on and turn-off. The recommended sequence is
V+ followed by VDD, always ensuring that V+ is the most positive
supply. The V- supply is not critical and can be asserted at any time.
MASTER RESET (MR)
On a Master Reset data transmission and reception are immediately terminated, all three FIFOs are cleared as are the FIFO flags
at the device pins and in the Status Register. The Control
Register is not affected by a Master Reset.
