Holt Expands Autonomous ARINC 429 Receiver Family Operating with no MCU

Thursday, April 09, 2015

Mission Viejo, CA (April 9, 2015) - Holt Integrated Circuits today added two new devices to its novel ARINC 429 receiver family designed specifically for use without a microprocessor. All configuration and control is programmed using logic input pins, eliminating the need for a microprocessor or software interface and the related costs for software certification. The new devices provide an optional parity check feature, discarding words received with parity errors.

The HI-8477 connects directly to the ARINC 429 bus and makes the data available at 32 digital output pins. The HI-8478 option provides the inverse (compliment) of the HI-8477 outputs. ARINC 429 label filtering is defined by 16 digital input pins, defining a maskable label match to enable reception of a single label or group of labels.

The device supports both high-speed and low-speed ARINC 429 data rates, operating from a 1MHz clock source and a single 3.3V or 5.0V power supply. The receiver inputs are lightning protected to RTCA/DO-160G, Section 22 Level 3 Pin Injection Test Waveform Set A (3 & 4), Set B (3 & 5A) and Set Z (3 & 5B) using only two external resistors.

“Holt’s range of autonomous ARINC 429 line receivers and line drivers operate without the need for a microprocessor or control software,” said Anthony Murray, Director of Marketing Communications at Holt. “This eliminates expensive software certification, providing our customers with smaller, lower cost solutions.”

The devices are available in a 64-pin PQFP package in industrial (−40oC to +85oC) and extended (−55oC to +125oC) temperature ranges.
