Holt HI-8584PQIF-10 Enhanced arinc 429 serial transmitter and dual receiver Datasheet

HI-8584
GENERAL DESCRIPTION
FEATURES
The HI-8584 from Holt Integrated Circuits is a silicon gate
CMOS device for interfacing a 16-bit parallel data bus to the
ARINC 429 serial bus. The HI-8584 design offers many
enhancements to the industry standard HI-8282
architecture. The device provides two receivers each with
label recognition, a 32 by 32 FIFO, and an analog line
receiver. Up to 16 labels may be programmed for each
receiver. The independent transmitter also has a 32 by 32
FIFO. The status of all three FIFOs can be monitored using
the external status pins or by polling the HI-8584’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 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.

Enhanced ARINC 429
Serial Transmitter and Dual Receiver
The HI-8584 applies the ARINC protocol to the receivers
and transmitter. Timing is based on a 1 Megahertz clock.
Additional interface circuitry such as the Holt HI-8585,
HI-8586 or HI-3182 is required to translate the transmitter’s 5 volt logic outputs to ARINC 429 drive levels.

FUNCTIONAL DESCRIPTION
CONTROL WORD REGISTER
STATUS REGISTER
The HI-8584 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:
The HI-8584 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.

FUNCTIONAL DESCRIPTION (cont.)
The HI-8584 guarantees recognition of these levels with a common
mode Voltage with respect to GND less than ±4 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-8584
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-8584 accepts signals that meet these

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 rate is checked. With exactly 1MHz input clock frequency,
the acceptable data bit rates are as follows:
COMPARATORS
ONES
GND

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 32nd bit of received ARINC words stored in the receive FIFO
is used as a Parity Flag indicating whether good Odd parity is
received from the incoming ARINC word.
Odd Parity Received
The parity bit is reset to indicate correct parity was received
and the resulting word is written to the 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.

Once 32 valid bits are recognized, the receiver logic generates an

checked for correct decoding and label matching before being
loaded into the 32 x 32 receive FIFO.

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 BD00 - BD07.
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 HI8584’s 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.

FUNCTIONAL DESCRIPTION (cont.)
DATA TRANSMISSION
REPEATER OPERATION
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 429DO and 429DO. 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:
Repeater mode of operation allows a data word that has been
received by the HI-8584 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.

The word counter detects when all loaded positions have been
transmitted and sets the transmitter ready flag, TX/R, high.
TRANSMITTER PARITY
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.
HI-8584-10
The HI-8584-10 option is similar to the HI-8584 with the exception
that it allows 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.
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.
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. The serial
data from the transmitter is always present on the 429DO and
429DO outputs 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.
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-8584 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.
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.
2. The transmitter FIFO can store 32 words maximum and
ignores attempts to load additional data if full.
