Octal ARINC 429 Receivers
with Label Recognition and SPI Interface
GENERAL DESCRIPTION
The HI-359x family from Holt Integrated Circuits are sili-
con gate CMOS ICs for interfacing up to eight ARINC
429 receive buses to a high-speed Serial Peripheral
Interface (SPI) enabled microcontroller. Each receiver
has user-programmable label recognition for up to 16
labels, a four-word data buffer (FIFO), and an on-chip
analog line receiver. Receive FIFO status can be moni-
tored using the programmable external interrupt pins,
or by polling the status register. Other features include
the ability to switch the bit-signifiance of the ARINC 429
label and to recognize the 32^nd received ARINC bit as
either data or a parity flag. Some versions provide a digi-
tal transmit channel which can be utilized with an exter-
nal line driver such as HI-8570 to relay information from
multiple sources, for example sensors, to a single col-
lection point such as a flight computer and can also be
configured as a loopback test register for each receive
channel. Versions are also available with different input
resistance values to provide flexibility when using exter-
nal lightning protection circuitry. The SPI and all control
signals are CMOS and TTL compatible and support
3.3V or 5V operation.
• 32^nd bit can be data or parity
• Low Power
• Industrial & extended temperature ranges

The HI-3596 and HI-3598 are full featured parts. The
HI-3597 and HI-3599 give the user the option of utilizing
a smaller 24-pin SOIC package with very little trade off in
features. In this case, a global interrupt flag is provided
instead of individual external FIFO interrupt pins. The
HI-3597 is identical to the HI-3599 except that it offers
the digital transmit feature and seven receive channels.
