HI-3582A, HI-3583A
ARINC 429
3.3V Terminal IC with High-Speed Interface
GENERAL DESCRIPTION
The HI-3582A/HI-3583A from Holt Integrated Circuits are
silicon gate CMOS devices for interfacing a 16-bit parallel
data bus directly to the ARINC 429 serial bus. The
HI-3582A/HI-3583A design offers a high-speed host CPU
interface compared with the earlier HI-3582/HI-3583
products. 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-3582A/HI-3583A status register. Other 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 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 3.3V CMOS compatible.
The HI-3582A/HI-3583A apply the ARINC protocol to the
receivers and transmitter. Timing is based on a 1 Mega-
hertz clock.
APPLICATIONS
• Avionics data communication
• Serial to parallel conversion
• Parallel to serial conversion
