Aliso Viejo, CA (March 22, 2022) – Holt Integrated Circuits today announced the release of a new ARINC 429 Development Kit, ADK-35981. The evaluation board demonstrates the operation of Holt's HI-35981, an Octal ARINC 429 Receiver with Label Recognition and a SPI Interface.
The kit is composed of two boards, a lower processor mother board and an upper HI-35981 demonstration board. The 2-board assembly and C project reference design provides a ready-to-run evaluation platform that demonstrates the basic operation of the device. The kit includes full project software and source files and for convenience, the IAR Systems Embedded Workbench® for ARM and a fully integrated debug interface for the ARM Cortex M3 microcontroller. A version of the demonstration software is pre-programmed into the microcontroller flash and the board is operational right out of the box without installing or running the provided software development tools.
The HI-35981 device is an enhanced version of Holt’s well-established HI-35980 (HI-3598) family with additional features and functionality. The user-programmable label filtering capability has been expanded from 16 labels to all 256 labels, and the 4-word deep receive FIFO has been increased to 32 words deep. In addition, a 32-word deep transmit FIFO has been added, significantly increasing the transmit capability from the single-word buffer on the existing device.
Each receiver channel has an integrated line receiver, allowing direct connection to an ARINC 429 bus, and a choice of inputs to enable the use of external resisters for lightning protection.
“This board provides our customers with a comprehensive reference design for ARINC 429 receivers,” said George Noh, Director of Sales and Marketing at Holt. “The kit includes full project software and source files and is operational right out of the box without installing or running the provided software development tools.”
