This kit demonstrates most features of the HI-8582/8583 5V ARINC 429 Terminal IC. The HI-8582/8583 features a single transmitter with integrated line driver and two receivers. The transmitter and both receivers utilize 32 x 32 FIFOs. A 16-bit parallel data bus is used for interfacing to a microcontroller or FPGA. Note, for 3.3V applications the HI-3582A/3583A is available.
The 2-board Holt evaluation kit uses an Atmel Cortex M3 32-bit microcontroller (MCU) to demonstrate the features of the device. The MCU is located on the lower board and a separate HI-8582/8583 daughter card plugs in on top of the MCU board. The daughter card can be removed from the lower board and used separately with another host FPGA / MCU interface. A serial port in the MCU displays ARINC 429 transmits and receives words on the console when the computer runs a terminal emulation program like HyperTerminal or TeraTerm. The demo program includes a menu of commands entered from the console to alter the configuration of the HI-8582 (or HI-8583) by modifying the Control Word register bits on-the-fly. Using the console commands provide a convenient way to learn the HI-8582 by making changes and seeing the effect on ARINC 429 words displayed on the console or by viewing the transmissions on an oscilloscope.
