Datasheet
GENERAL DESCRIPTION
The HI-3584 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-3584 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-3584’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 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-3584 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 or
HI-8586 is required to translate the transmitter’s 3.3 volt
logic outputs to ARINC 429 drive levels.

... FUNCTIONAL DESCRIPTION CONTROL WORD REGISTER The HI-3584 contains a 16-bit control register which is used to con- figure the device. The control register bits CR0 - CR15 are loaded from BD00 - BD15 when CWSTR is pulsed low. The control regis- ter contents are output on the databus when SEL = 1 and pulsed low ...

... 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 ...

... CR2-CR11, the received ARINC 32-bit word is then checked for correct decoding and label matching before being loaded into 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 ...

... PL2 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 words, each 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 FIFO ignores further attempts to load data ...

... The parity generator counts the Ones in the 31-bit word. 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. ...
