FEATURES
GENERAL DESCRIPTION
The HI-3587 from Holt Integrated Circuits is a silicon gate
CMOS device for interfacing a Serial Peripheral Interface
(SPI) enabled microcontroller to an ARINC 429 serial bus.
The device provides one ARINC 429 transmitter with 32 X
32 Transmit FIFO and built-in line driver. Transmit FIFO
status can be monitored using the programmable external
interrupt pin, or by polling the HI-3587 Status Register.
Other features include a programmable option of data or
parity in the 32nd bit, and the ability to switch the bit-
signifiance of ARINC 429 labels. Line driver output pins
are available with different values of output resistance to
provide flexibility when using external lightning protection
circuitry.
The Serial Peripheral Interface minimizes the number of
host interface signals and provides a small footprint device
that can be interfaced to a wide variety of industry-
standard microcontrollers supporting SPI. Alternatively,
the SPI signals may be controlled using four general
purpose I/O port pins from a microcontroller or custom
FPGA. The SPI and all control signals are CMOS and TTL
compatible and support 3.3V or 5V operation.
The HI-3587 applies the ARINC 429 protocol to the
transmitter. ARINC 429 databus timing comes from a 1
MHz clock input, or an internal counter can derive it from
higher clock frequencies having certain fixed values,
possibly the external host processor clock.
